|
|
|
Chairman Bowman. Good afternoon, everyone. Welcome to our |
|
hearing entitled ``Building Technologies Research for a |
|
Sustainable Future.'' This hearing will come to order. Without |
|
objection, the Chairman is authorized to declare recess at any |
|
time. |
|
Before I deliver my opening remarks, I wanted to note |
|
that, today, the Committee is meeting today virtually. I want |
|
to announce a couple of reminders to the Members about the |
|
conduct of this hearing. First, Members should keep their video |
|
feed on as long as they are present in the hearing. Members are |
|
responsible for their own microphones. Please also keep your |
|
microphones muted unless you are speaking. Finally, if Members |
|
have documents they wish to submit for the record, please email |
|
them to the Committee Clerk, whose email address was circulated |
|
prior to the hearing. |
|
I now recognize myself for an opening statement. |
|
Good afternoon, and thank you to all of our witnesses who |
|
are joining us virtually today to discuss the importance of |
|
sustainable buildings research. This is a critical component of |
|
fighting the climate crisis. |
|
In my State of New York, we have some of the most densely |
|
populated cities in the country. We also have some of the most |
|
aggressive climate goals in the world. Thanks to a broad |
|
coalition of social movements, New York State passed the |
|
Climate Leadership and Community Protection Act in 2019. Part |
|
of this law was the inspiration for President Biden's Justice40 |
|
Initiative, which will channel 40 percent of the Federal |
|
Government's climate investments into marginalized communities. |
|
Also in 2019, New York City passed a first-of-its-kind law to |
|
cut greenhouse gas emissions from buildings. Now, we need to |
|
come together as a nation and build on these victories at the |
|
Federal level. |
|
When we think of reducing emissions, we often think of |
|
renewable power or electrifying our transportation sector. But |
|
another large source of emissions, especially in New York, is |
|
buildings. Currently, about 40 percent of our country's carbon |
|
dioxide emissions comes from the structures that we live, work, |
|
and sleep in, and that we depend on for life-sustaining care. |
|
This goes to the heart of why we need to address climate |
|
change, inequality, and racism together. |
|
As we have been discussing on this Committee, when climate |
|
disasters strike, redlined communities of color and low-income |
|
people are hit hardest. They're the first to lose power when |
|
the electricity grid is strained, as we saw in Texas. And these |
|
are the same communities that struggle with housing and utility |
|
costs. They face health risks from toxic materials in |
|
buildings, including in public housing that we have allowed to |
|
fall into a state of disrepair. In my district and around the |
|
country, the people who live in these buildings have been dying |
|
at higher rates from COVID, partly because of co-morbidities |
|
caused by the fossil fuel economy. We need sustainable |
|
buildings now, and we need to rebuild our communities from the |
|
ground up. |
|
The Department of Energy (DOE) invests millions of dollars |
|
every year in improving building technologies in a variety of |
|
ways. DOE, along with other Federal science agencies, plays a |
|
role in making buildings more resilient to extreme weather. DOE |
|
also researches energy efficiency and increased electrification |
|
in buildings, with an emphasis on ensuring the equitable |
|
distribution of the effects of this clean energy research. |
|
Let's also think about how Federal research can become |
|
more interdisciplinary. Social scientists, for example, have |
|
started exploring how green investments in neighborhoods can |
|
lead to gentrification. This process is not only unjust but can |
|
undermine climate goals. Instead of cutting emissions for |
|
everyone, this can create a low-carbon economy for people with |
|
privilege, while displacing communities of color and other low- |
|
income people out of dense, walkable neighborhoods. We need a |
|
combination of natural science, engineering, and social science |
|
to guide equitable and effective green investments for |
|
everyone. |
|
And research alone won't be enough. The other work that |
|
DOE must continue to focus on is how to get the results of this |
|
research into the hands of the communities that need it most. A |
|
week ago, I released a proposal to heal our K-12 school system |
|
from the impacts of climate change and the pandemic, and from |
|
decades of disinvestment. A huge part of this plan is focused |
|
on retrofitting public school buildings and removing toxic |
|
materials, beginning in the highest-need districts. Schools can |
|
become living laboratories for the energy transition, putting |
|
students and young people at the center of the Green New Deal, |
|
and launching STEM (science, technology, engineering, and |
|
mathematics) careers across the country. |
|
Big problems require big solutions, and that is exactly |
|
what we will be pursuing together on this Committee. I am |
|
excited to chair the Energy Subcommittee this Congress and to |
|
hold this first Subcommittee hearing on such an important |
|
topic. Investing in building technologies means investing in a |
|
safe, healthy future for our country and for the entire world. |
|
I want to thank our excellent panel of witnesses assembled |
|
today, and I look forward to hearing your testimony. With that, |
|
I yield back. |

|
I want to again thank our excellent panel of witnesses |

assembled today, and I look forward to hearing your testimony. |
|
With that, I yield back. |
|
|
|
Chairman Bowman. The Chair now recognizes Mr. Weber for an |
|
opening statement. |
|
Mr. Weber. Well, thank you, Mr. Chairman, and welcome to |
|
the Committee. We're going to have a little fun. We're going to |
|
be a lighthearted Committee, and we're going to be very serious |
|
about our work, serious about what we do with energy and for |
|
our country, so I appreciate you being here Chairman Bowman. |
|
All of my thanks I want to add to all the witnesses for being |
|
with us here virtually this afternoon. |
|
I will tell you that, today, we're going to discuss |
|
building technology research and development (R&D) needs. And |
|
while I'm excited to hear about the critical work being |
|
performed by the Department of Energy's Building Technologies |
|
Office and, quite frankly, all across DOE, I want us all to be |
|
mindful of the role that industry can and should play in this |
|
area, especially where there is a clear incentive and an |
|
ability to take up mature technologies. |
|
I say this as someone who knows the building industry |
|
firsthand. In the 1970's, I couldn't even spell air |
|
conditioning or what we call AC in Texas, but by the mid-'90's |
|
I was actually running my own AC company. And I can tell you |
|
this: Whether it's through regulation, taxation, mandates, |
|
businesses suffer when the government gets heavy handed and |
|
intervenes, so we have to take a very careful approach. |
|
Today, we must also remember that we have limited Federal |
|
research and development dollars. The Department of Energy |
|
mainly supports building technology research and development |
|
through their Office of Energy Efficiency and Renewable Energy, |
|
which I am inclined to mention is the highest funded applied |
|
energy office at the Department with a budget this past year |
|
alone of $2.8 billion with a B. That's why I have long |
|
prioritized investment in basic and early stage research that |
|
will drive innovation into the next century and not just for |
|
building technologies but across our entire energy and |
|
efficiency portfolio. |
|
DOE's world-leading national laboratories support that |
|
type of cutting-edge research that we're talking about here |
|
today. National labs around the country, from Oak Ridge and |
|
NREL (National Renewable Energy Laboratory) to Argonne and |
|
Lawrence Berkeley National Lab, are leveraging DOE's unique |
|
capabilities and user facilities to support critical |
|
discoveries in innovative material science, data analytics, and |
|
advanced sensors and controls. And private-public partnerships |
|
with these labs are exactly how we get the most bang for our |
|
taxpayers' buck when investing taxpayers' dollars in this |
|
research. DOE partnerships with industry and academia enable |
|
the development of new technologies that can increase the |
|
energy efficiency of building envelopes, improve construction |
|
practices, and meet the demand for greater energy generation |
|
capacity. |
|
Today, we will hear from Dr. Jim Tour of Rice University |
|
in my home State of Texas, who will give us his perspective as |
|
one of those partners. As a professor of chemistry along with |
|
materials science and nanoengineering, Dr. Tour's research |
|
focuses on advanced building materials like, for example, |
|
lighter, stronger concrete that is a result of turning waste |
|
into a manufacturing additive called graphene. I look forward |
|
to hearing his testimony on how fundamental materials research |
|
can transform building technologies and at the same time how |
|
successful public-private partnerships have supported these |
|
innovations. |
|
And just like Dr. Tour's example of turning trash into |
|
treasure, we can support a future that protects our environment |
|
for the next generation and is affordable for all Americans. |
|
But we won't necessarily accomplish this by doing what we call |
|
in Texas, just throwing in the kitchen sink and billions of |
|
dollars at a broad, unspecified portfolio. Instead, we should |
|
make our clean technology affordable through significant |
|
investment in fundamental research paired with targeted and |
|
responsible investments in applied energy R&D. |
|
That is why, this week, I was proud to sign on as one of |
|
the original cosponsors of Ranking Member Lucas' Securing |
|
American Leadership in Science and Technology Act. This |
|
legislation supports a diverse, all-of-the-above clean energy |
|
strategy and prioritizes critical research to establish U.S. |
|
leadership in industries of the future, like advanced materials |
|
and manufacturing. This long-term strategy for investment in |
|
basic research and infrastructure is how we in Congress should |
|
support innovative building technologies. It creates a pipeline |
|
from lab to market and is the most direct and efficient path to |
|
a more sustainable future for both new and current buildings. |
|
Thanks to the witnesses. Thank you, Mr. Chairman. I yield |
|
back. |
|
[The prepared statement of Mr. Weber follows:] |
|
|
|
Thank you, Chairman Bowman, for hosting this hearing, and |
|
thank you to all our witnesses for being with us virtually this |
|
afternoon. Today is the first Energy Subcommittee hearing of |
|
the 117th Congress and I'm looking forward to continuing the |
|
bipartisan successes that have marked my time here. |
|

|
[The prepared statement of Chairwoman Johnson follows:] |
|
|
|
Good Afternoon and thank you Chairman Bowman for holding |
|
this hearing today, as well as to all of our witnesses for |
|
being here. |
|
The sustainability of our buildings is a topic that touches |
|
on every American across the country. |
|
Buildings make up almost 40% percent of the total energy |
|
consumption in the United States, and reducing that consumption |
|
can not only decrease our electric bills, but also |
|
significantly reduce our greenhouse gas emissions. |
|
My own city of Dallas, Texas is the fastest growing |
|
metropolitan area in the U.S. Our growing population supports a |
|
growing economy, but we must ensure that new infrastructure to |
|
meet these needs is built with the most up-to-date technologies |
|
to provide efficiency, comfort, and resilience. |
|
Existing buildings are another key component of federal |
|
research, development, and demonstration activities. Many of |
|
the advancements that have been made on improving heating, |
|
cooling, windows, and lighting can be more easily applied to |
|
new construction projects, but our existing buildings are not |
|
going away any time soon. Retrofit technologies can help to |
|
equitably distribute local and federal resources, as some of |
|
the communities that could most use healthier, cleaner, and |
|
more resilient buildings have aging infrastructure. |
|
As we have seen with recent, devasting events in my home |
|
state of Texas, ensuring the resilience of our grid is |
|
paramount. When constructing new buildings, grid connectivity |
|
could be a key element in alleviating energy demand and |
|
improving reliability through next-generation sensors, |
|
controls, and communication technologies. I look forward to |
|
hearing how our national labs and the Building Technologies |
|
Office within the Department of Energy can help us achieve |
|
these goals. |
|
Buildings affect all aspects of our daily lives, and we |
|
should be doing everything we can to ensure that we are laying |
|

TESTIMONY OF DR. NORA ESRAM, SENIOR DIRECTOR |
|
|
|
FOR RESEARCH AT AMERICAN COUNCIL |
|
|
|
FOR AN ENERGY-EFFICIENT ECONOMY |
|
|
|
Dr. Esram. Thank you. Chairman Bowman, Ranking Member |
|
Weber, and Members of the Committee, thank you for inviting me |
|
to testify on the topic of building technologies research and |
|
development. I bring with me today my 20 years of knowledge and |
|
experience as an architect, an educator, a lab scientist, and |
|
now as a Research Director at American Council for an Energy- |
|
Efficient Economy. |
|
Building efficient technologies are known to lower energy |
|
costs and create local jobs, but the biggest opportunities are |
|
still ahead. Improving efficiency of buildings has the |
|
potential to reduce U.S. greenhouse gas emissions by 20 |
|
percent. The industry needs help from the Federal Government |
|
and science community to develop integrated solutions and |
|
productive processes to upgrade existing buildings faster. |
|
Building retrofits also improve occupants' health, |
|
comfort, productivity, and community resilience. Today, many of |
|
our buildings don't serve us well. For instance, when COVID-19 |
|
hit, public health experts suggested increasing indoor |
|
ventilation and filtration to lower this ease of transmission |
|
risk, but many legacy building systems can't handle that. When |
|
offices were sitting empty during the lockdown, they still |
|
consumed 40 to 100 percent of their usual energy. That's a huge |
|
waste. When the power went out across much of Texas, many |
|
poorly insulated homes quickly dropped to near freezing |
|
temperature. Imagine if these houses could have been kept warm |
|
with a heating device as small as a hairdryer. That's not a |
|
dream. That's efficiency building technologies. |
|
Thanks to decades of Federal investment in research, we |
|
have many technologies to make buildings efficient, healthier, |
|
and resilient for everyone. But we don't know yet how to |
|
expeditiously deliver these technologies to existing buildings. |
|
Improving construction productivity offers a path. If |
|
construction labor productivity were to catch up with the |
|
progress made by other sectors, we will gain $1.6 trillion |
|
economic growth globally. A third of that is in the United |
|
States. |
|
Many countries are moving onsite construction toward a |
|
manufacturing inspired mass production platform. We'll lose our |
|
competitive edge if we don't take bold actions. Transforming |
|
the building industry would also provide an opportune time to |
|
reduce embodied carbon in building materials and products. |
|
I also believe a strong and a creative workforce is key to |
|
success. We need to equip the building contractors and |
|
specialized trades with knowledge and skills to adapt to new |
|
technologies. We need to educate and attract a new generation |
|
of innovators and entrepreneurs. Buildings of the future are |
|
machines that interact with the grid and transportation |
|
systems. Workforce development is a creative and interactive |
|
process. Therefore, we need Federal R&D support to grow |
|
tomorrow's building leaders outside the classroom. |
|
I urge Congress and DOE to take bold actions to lay a |
|
solid foundation for a successful transmission of the building |
|
sector. First, spur modernized approaches to accelerate deep |
|
energy retrofits and create local jobs. Second, train and |
|
diversify our workforce and inspire a new generation of |
|
leaders. Third, drive enduring market transformation through |
|
integration of efficiency with health, resilience, and other |
|
societal goals. Last but not least, collaborate with local and |
|
State governments and community-based organizations to create |
|
proactive, replicable solutions for all. |
|
I truly believe that we are facing a paradigm shift. |
|
Together, we can both create and witness history. Thank you |
|
again for the opportunity to testify, and I look forward to |
|
your questions. |

TESTIMONY OF DR. RODERICK JACKSON, |
|
|
|
LABORATORY PROGRAM MANAGER |
|
|
|
FOR BUILDINGS RESEARCH |
|
|
|
AT NATIONAL RENEWABLE ENERGY LABORATORY |
|
|
|
Dr. Jackson. Thank you to the Subcommittee for giving me |
|
this opportunity today to provide a testimony on a topic of |
|
critical national importance and deep personal passion. So my |
|
bio is included in the written testimony for reference, so I |
|
won't get into those details, but I wanted to provide a |
|
personal perspective of who I am and my passion. |
|
So my father, Louis C. Jackson, was one of 16 children, |
|
and out of 16--and out of 11 boys, they all built houses. So |
|
construction was a deep passion for my dad, so much so that he |
|
first introduced it to me when I was only 3 years old. I think |
|
my first job was to go out on the jobsite and pick up all the |
|
straight nails. |
|
A little after finishing my undergraduate degree, he and I |
|
formed L&R Jackson Construction back in my hometown of Canton, |
|
Mississippi. However, my personal passion for science and |
|
engineering drew me back to Georgia Tech to complete my Ph.D., |
|
but the legacy my dad and my brothers, [inaudible] was never |
|
far from my heart. |
|
I have since been able to marry my love for science with |
|
family legacy, and that brings me here today. Unfortunately, my |
|
dad passed away on January 19th, 2021, but the opportunity to |
|
provide testimony on the future of the industry he so--he loved |
|
so dearly is immensely fulfilling. |
|
So let's talk science. Because buildings consume about 3/4 |
|
of our current electricity demand, they can be a large part of |
|
the sustainable energy solution. By leveraging energy |
|
efficiency, greater connectivity, advanced data science and |
|
analytics, along with next-generation materials, sensors, and |
|
controls, buildings can be designed to synergistically interact |
|
in real-time with the electric grid to provide demand |
|
flexibility, all while not compromising comfort, health, or |
|
productivity. |
|
DOE is leading the charge in this new vision for the |
|
pivotal role that buildings can play and has appropriately |
|
titled this initiative Grid-Interactive Efficient Buildings. In |
|
my written testimony I highlighted how modeling, sensors, and |
|
controls enable this future of Grid-Interactive Efficient |
|
Buildings by providing a platform to understand, plan, and |
|
optimize the performance of buildings in varying scenarios. I |
|
provided ResStock as an example of an idea first cultivated by |
|
laboratory directed R&D funds and developed by DOE funding and |
|
support. It is now currently being used by multiple research |
|
activities, as well as private-sector use cases. |
|
In my written testimony I also highlighted the need for |
|
thermal energy storage because thermal end uses like space |
|
conditioning, water heating, and refrigeration represent |
|
roughly half of our building energy demand. Thermal energy |
|
could be stored as a complement as well as an alternative to |
|
battery energy storage to balance supply and demand. |
|
Now, I'm particularly excited about a publication--NREL |
|
publication in this month's Nature Energy journal. It presented |
|
an analogous adaptation of the energy/power tradeoff curve that |
|
has been foundational in the design and advancement of battery |
|
systems. This and others are really just some of the examples |
|
of opportunities that we can use to further accelerate the |
|
deployment of thermal storage as a viable energy storage |
|
solution. |
|
So as we continue to advance the science of--science and |
|
engineering of individual Grid-Interactive Efficient Buildings, |
|
there are actually new possibilities that emerge to aggregate a |
|
collection of buildings with other local distributed resources |
|
into connected communities. So not only can we then see |
|
optimized solutions where the total is indeed greater than the |
|
sum of the individual parts, we can also enable innovation at |
|
the intersection of these diverse and distinct technology |
|
domains. |
|
However, unfortunately, according to a recent McKinsey |
|
study, labor productivity in the United States has remained |
|
stagnant over the last 80 years, approximately marking the time |
|
when the first Jacksons began to master the carpentry trade. So |
|
this reality not only hinders U.S. competitiveness, it limits |
|
the transition to a sustainable energy future with affordable |
|
building construction and retrofit costs. The DOE's Advanced |
|
Building Construction (ABC) Initiative targets this opportunity |
|
with a vision to integrate higher levels of energy efficiency |
|
into new construction and retrofits. |
|
But--so as we transition to a sustainable energy future, |
|
we have to ensure the benefits as well as the costs are more |
|
equitably distributed. Our examples of centering equity in |
|
energy technology innovation and energy transition are most |
|
often focused on the deployment phase of the research, |
|
development, demonstration, and deployment spectrum. However, |
|
while this is important and essential, deployment is the final |
|
stage of that technology spectrum I just described. And so as a |
|
result, in many cases, it actually may be more difficult to |
|
equitably deploy technology that was developed without regard |
|
to equity. In other words, this approach could be akin to |
|
attempting to force a square peg into a round hole. So, as an |
|
alternative, the R&D community, the community to which I |
|
belong, should take the additional step of centering equity |
|
into the early stages of the technology development pipeline. |
|
And then also due to historical under-investments, the |
|
solutions faced by low-income communities are actually |
|
different and actually distinctly more difficult to overcome in |
|
many cases, hence the need for science, engineering, and |
|
innovation are even more pressing. |
|
So in summary, thank you for this opportunity. And to meet |
|
our Nation's goal and continue our American leadership in |
|
energy innovation, we should continue to prioritize the R&D |
|
investments in building technologies. I look forward to any |
|
other questions you may have. Thank you. |

TESTIMONY OF DR. JAMES TOUR, |
|
|
|
T.T. AND W. F. CHAO PROFESSOR OF CHEMISTRY |
|
|
|
AT RICE UNIVERSITY |
|
|
|
Dr. Tour. Thank you, Mr. Chairman. I'm a professor of |
|
chemistry, material science, and nanoengineering at Rice |
|
University and part of the Welch Institute for Advanced |
|
Materials. I have 730 research publications, 234 of those on |
|
the topic of graphene. I have over 50 U.S. patents plus 90 |
|
international patents on graphene. In the past 6 years alone, |
|
my academic research has led to the formation of 14 companies, |
|
eight of those in nanomaterials, and two of them now public |
|
companies. |
|
On March 15, 2017, I gave testimony before the Energy and |
|
Commerce's Subcommittee on Digital Commerce and Consumer |
|
Protection on the topic of graphene and attaining U.S. |
|
preeminence. Four years later, I'm here to report that the |
|
future has arrived. |
|
What is graphene? Think of it as carbon chicken wire. |
|
That's what it looks like, chicken wire in its atomic |
|
arrangement but on the one-atom-thick scale. Graphene is a non- |
|
toxic, naturally occurring carbon material, and it's a |
|
glomerate to the natural mineral graphite. It is very slow to |
|
enter the carbon dioxide cycle, and hence it can be considered |
|
a terminal carbon sink with near zero contribution to |
|
greenhouse gas emissions. |
|
Graphene is a revolutionary material for building |
|
construction, but until recently, affordability and access to |
|
sufficient quantities made it only a dream for those |
|
applications. In 2018, a graduate student in my laboratory Duy |
|
Luong, working under funding from the Air Force Office of |
|
Scientific Research, discovered a process that we call flash |
|
graphene. We immediately filed patents to protect the |
|
technology, and companies were formed 1 year later, Universal |
|
Matter Inc. and Universal Matter Limited. |
|
The process can take any carbon material, any carbon |
|
material and convert it into graphene in less than 1 second |
|
using only electricity, no water, no solvents, no additives |
|
other than carbon itself. This new graphene manufacturing |
|
process will lower the cost by a factor of 10, therefore making |
|
it economically viable for use in building materials. |
|
The majority of waste products generated by human beings |
|
are carbon-based. If it's not rocks or water, it's probably |
|
carbon. We can take coal, petroleum coke, unsorted plastic |
|
waste, discarded food, mixed household waste, any other carbon |
|
source and convert it into graphene. Our production rate is |
|
doubling every 9 weeks, thereby projecting to hundreds-of-tons- |
|
per-day scale within 3 years. With grants from the Department |
|
of Energy and Department of Defense in collaborations with the |
|
Army Corps of Engineers, ERDC (Engineer Research and |
|
Development Center), Argonne National Laboratory, and several |
|
large automotive, concrete, asphalt, and wood manufacturers, |
|
we're developing graphene for concrete, asphalt, aluminum, |
|
plastics, polymer foams, lubricants, rubber, wood, fabric, and |
|
paint composites. By adding just .1 weight percent, that's 0.1 |
|
weight percent to cement, we get a 35 percent enhancement in |
|
compressive strength. It means we could use 1/3 less cement for |
|
construction. And since cement and concrete constitute 8 |
|
percent of all worldwide carbon dioxide emissions, that could |
|
translate into a remarkable diminution of emissions. |
|
Concrete alone is a $30 billion new market opportunity for |
|
graphene. Zero-point-five weight percent addition of graphene |
|
to asphalt will triple the life of the road. Zero-point-zero- |
|
five weight percent of graphene to carbon fiber composites will |
|
lower the weight of an aircraft by 20 percent, translating into |
|
enormous fuel and carbon dioxide reductions, all made possible |
|
by this U.S. invention. |
|
Through Rice University's carbon hub, we're developing |
|
methods to convert natural gas into hydrogen and graphene with |
|
near zero carbon dioxide emissions. That's clean hydrogen fuel |
|
from natural gas. The next step is developed--is to develop |
|
entirely new classes of graphene composites that can substitute |
|
for the energy-intensive 2,500-year-old materials that we use |
|
today like concrete and steel while providing a non-toxic |
|
carbon sink for most human waste products. |
|
The takeaway from my testimony is this: First, continue to |
|
foster basic support of basic and applied research directed |
|
toward advancement and deployment of new materials. A few years |
|
ago, graphene was only viewed as appropriate for ultrahigh-end |
|
aerospace and device applications but not anymore. The |
|
bipartisan Endless Frontier Act could embody an interesting |
|
approach to achieve the requisite research and translational |
|
goals. |
|
Second, it remains challenging to go from the lab bench to |
|
the build site with market profitability. Congress has immense |
|
power and influence over tax policy and administrative and |
|
regulatory burdens that can make or break our startup |
|
companies. |
|
Third and finally, streamlining the green card process for |
|
scientists and engineers that have received their Ph.D.'s in |
|
the United States so that people like Duy Luong, the Vietnamese |
|
graduate student that discovered the flash graphene process in |
|
my laboratory, can stay to develop their discoveries in our |
|
Nation's companies. We just need to do it right, safeguarding |
|
U.S. intellectual property through background checks and |
|
security oversight. Thank you. |

TESTIMONY OF MS. JACQUELINE PATTERSON, |
|
|
|
DIRECTOR OF ENVIRONMENTAL |
|
|
|
AND CLIMATE JUSTICE PROGRAM, NAACP |
|
|
|
Ms. Patterson. Thank you so much. It's an honor to be here |
|
with you all. And I appreciate being--having the opportunity to |
|
share these brief remarks. |
|
So the NAACP, when we first started doing this work, |
|
people were surprised that we were working on energy, much less |
|
the sustainable building sector. However, as one considers the |
|
extreme disparities in equality, safety, and health of the |
|
places where African American communities especially live, |
|
learn, and work, play, and worship, for us the historic social, |
|
political, and economic disenfranchisement has been detrimental |
|
to generational well-being. |
|
In 1861 and 1862 the United States Government passed the |
|
Morrill and Homestead Acts, which were intended to give land |
|
grants to White Americans for colleges and those seeking land |
|
to farm. These acts were also accompanied by offers of |
|
subsidies to facilitate the acquisition and use of the land. As |
|
slavery was not abolished in the United States until 1865, many |
|
enslaved and freed African Americans were unable to benefit |
|
from these acts, and a lack of legal services meant that |
|
African Americans who managed to acquire land couldn't even |
|
write legally binding wills that would facilitate legalized |
|
inheritance of property. |
|
This is all tied to the fact that overall economic |
|
insecurity has resulted in extreme income and wealth |
|
differentials that persist over centuries. Even now at $171,000 |
|
in net worth of a typical White American family is nearly 10 |
|
times greater than that of a Black American family at $17,150. |
|
And for Black American single women-headed households, the |
|
average family net worth is only $5. At 44 percent, African |
|
Americans are least likely to be homeowners, whereas it's 75 |
|
percent of White Americans and overall 65 percent for the |
|
Nation. |
|
Historic and modern-day redlining practices impact |
|
everything from whether we own homes, where we own homes, and |
|
the quality of the homes and other resources to which we have |
|
access. Also impacting is the quality of the infrastructure in |
|
our communities such as levees that protect our homes, and |
|
property values that finance our schools are also--also affects |
|
the quality of the buildings in which our schools are housed. |
|
Subpar quality of the buildings and structures in our |
|
communities means that we are inundated by energy burden, which |
|
challenges our finances, indoor air pollution which sickens our |
|
family, and poor housing stock, which renders us vulnerable |
|
when disaster impacts. |
|
African Americans have the highest energy burden, which |
|
means that the amount of income that goes toward energy in the |
|
buildings we occupy is the highest of any other racial and |
|
ethnic group. African Americans are also more likely to have |
|
our energy shut off for nonpayment, too often with fatal |
|
impacts as we pay the price of poverty and racism with our very |
|
lives when a candle or a space heater or carbon monoxide has |
|
taken the lives of too many seeking to heat or light our homes |
|
when our finances can't meet the demands of our bills. |
|
Yet we're more likely to suffer from the pollution being |
|
emitted from energy production as we are more likely to live |
|
near coal-fired power plants, oil and gas refineries, waste-to- |
|
energy incinerators, et cetera, and we pay the price with our |
|
health. We are more likely to bear the impacts of climate |
|
change that results from emissions from buildings. |
|
We also know that energy improvements, whether it's |
|
weatherization, retrofits, and clean energy like solar are tied |
|
to homeownership and credit ratings, which are compromised by |
|
the historic and current factors I've already described. |
|
COVID-19 means that we are in buildings more due to remote |
|
working and due to the need for isolation, which means we are |
|
using more energy and also are more exposed to indoor air |
|
pollution. |
|
With 2020 being the hottest year on record as part of the |
|
progression of increasingly hotter years, as well as greater |
|
weather extremes, our ability to cool and heat our homes |
|
reliably and affordably becomes increasingly more critical. Yet |
|
communities and populations most impacted by these disparities |
|
are underrepresented in the building sector and professions, |
|
including those working on building standards in terms of |
|
organizations, architects, and beyond. For example, just .03 |
|
percent of certified architects are Black women, while, again, |
|
$5 is the average wealth of a single Black woman-led household, |
|
thereby arguably rendering us as Black women as the No. 1 |
|
critical stakeholder in the future of buildings. |
|
Key steps to right the wrong--right the historic and |
|
present-day wrongs include campaign-finance reform so that |
|
money interests don't have their thumb on the scale of the |
|
change we need to have in advancing energy justice for all. |
|
Dismantling the weapons of mass distraction, including the |
|
formulas that tie property values with quality of |
|
infrastructure and services at the local level, increasing |
|
investments in BIPOC, Black, indigenous, and people of color in |
|
education and leadership in STEM, increasing resources for job |
|
and business opportunities for BIPOC communities, and shifting |
|
wealth to community-led endeavors to develop sustainable, |
|
affordable, safe, and healthy infrastructure, including |
|
buildings. |

TESTIMONY OF MR. JOSEPH HAGERMAN, GROUP LEADER |
|
|
|
FOR BUILDING INTEGRATION AND CONTROLS |
|
|
|
AT OAK RIDGE NATIONAL LABORATORY |
|
|
|
Mr. Hagerman. Thank you. Chairman Bowman, Ranking Member |
|
Weber, and distinguished Members of the Subcommittee, thank you |
|
for the opportunity to virtually appear before you today. My |
|
name is Joe Hagerman. I lead the Building Technologies Research |
|
Section at the U.S. Department of Energy's Oak Ridge National |
|
Lab in Oak Ridge, Tennessee. I'm a building technologies |
|
researcher by education and training. |
|
I'm not going to take our time today to discuss how much |
|
energy is consumed in buildings. We all pay energy bills at the |
|
end of the month. In fact, last year, buildings used 74 percent |
|
of all the electricity in the Nation at a cost of over $332 |
|
billion. I think we can all agree that's a big bill. |
|
I want to focus today on the impact that Oak Ridge has |
|
made with the support of DOE Building Technologies Office. It |
|
is our thesis that when our Nation's buildings are cleaner and |
|
more efficient and--the effect can be profound, improving |
|
comfort, safety, productivity, and it will take American labor |
|
and American jobs to realize these benefits. |
|
So what's Oak Ridge doing? Staff at the lab are |
|
accelerating clean energy innovation throughout the buildings' |
|
ecosystem. Our Nation's fastest supercomputer at Oak Ridge's |
|
speeds modeling and simulations to analyze the potential for |
|
retrofits down to the neighborhood level for every building in |
|
America. Our nanomaterials science leads to new building |
|
materials with extraordinary insulation and self-healing |
|
properties. And our engineering expertise continues to drive |
|
breakthroughs for new energy-efficient equipment like cold |
|
climate heat pumps, climate-friendly refrigerants, and advanced |
|
next-generation appliances. A lot of this sounds like science |
|
fiction, but it's not. It's science fact, and that's the |
|
current seat of the lab, transformational science. |
|
The cornerstone for our research is of course our |
|
facilities, particularly the Building Technologies Research and |
|
Integration Center or BTRIC. BTRIC is DOE's only user facility |
|
dedicated to accelerating breakthroughs for clean energy- |
|
efficient buildings. But the largest contributor to our work is |
|
our partnerships. We partner with industries, universities, and |
|
communities, and we make good partners because success to my |
|
staff is clear: make positive, practical impact. |
|
Let me share with you about working with the lab. The |
|
sheer volumes of connections, interactions, and collaborations |
|
are what make Oak Ridge a special place to work. We foster |
|
great science because we invest in great diverse people, |
|
expertise, and skills. And equally important we have clear |
|
goals. Our first goal is that Oak Ridge will continue to lead |
|
the building energy efficiency research for the Nation. One |
|
example is how Viral Patel and his team at Oak Ridge developed |
|
piezoelectric drying science that mechanically shakes and |
|
vibrates fabric at a high frequency to remove moisture. They |
|
demonstrated a faster drying time with five times less energy |
|
that will one day reshape conventional residential dryers. To |
|
me that's transformative. |
|
But let's transform it again here today by recognizing |
|
that these innovations can also provide a solution to the hard- |
|
to-decarbonize industrial sector. This is another important |
|
thesis to the lab's research and science. Our advancements can |
|
apply to other processes, and it's my hope that American |
|
companies engage with us to decarbonize all sectors. |
|
Our second goal, Oak Ridge will continue to pioneer |
|
connected smart communities for grid resilience, benefiting |
|
consumers and the grid equally. Group leader Heather Buckberry |
|
worked with Southern Company, Alabama Power, and Georgia Power |
|
to provide and prove that homes and businesses can provide a |
|
central stability to the grid. Heather and her team |
|
demonstrated that more than 30 percent decreased overall energy |
|
consumption and an approximately 35 percent lower demand during |
|
peak winter, all with no impacts to comfort. More importantly, |
|
residents engage with their buildings and controls in no |
|
different way than normal, and that's Heather's thesis: Control |
|
science can be done behind the scenes, and with Oak Ridge's |
|
deep bench in cybersecurity, we can guard the associated data |
|
and control actions. |
|
Goal No. 3, Oak Ridge will help lead the Nation in meeting |
|
our decarbonization goals. Another group leader Kashif Nawaz is |
|
developing direct air carbon capture solutions with building |
|
equipment technologies. Looking forward, Kashif hopes to |
|
develop concepts and methods for net negative carbon buildings |
|
where equipment can efficiently heat, cool, dehumidify the air |
|
while capturing CO<INF>2</INF>, all possible by relying on |
|
transformative science, not science fiction. |
|
In closing, Oak Ridge is a foundational partner that can |
|
accelerate the clean energy transition across the Nation to all |
|
communities, and the challenges ahead to the Nation are great. |
|
I believe they are bigger than one person, one team, or one lab |
|
alone. It's going to take all of us, not some of us, to achieve |
|
our goals, but from great challenges, great opportunities |
|
emerge, opportunities for equities, collaboration, and allies |
|
across the sciences, and opportunities to create good-paying |
|
American jobs while we're at it. |
|
I'm proud to work for my staff every day and honored to |
|
work at Oak Ridge National Laboratory. Thank you. |
|
[The prepared statement of Mr. Hagerman follows:] |
|
[GRAPHICS NOT AVAILABLE IN TIFF FORMAT] |
|
|
|
Chairman Bowman. Thank you, Mr. Hagerman. |
|
At this point we will begin our first round of questions. |
|
The Chairman recognizes himself for 5 minutes. |
|
Dr. Esram, thank you for your testimony. I appreciated |
|
your emphasis on the need to align carbon reduction with other |
|
social goals such as health and equity. I want to zero in on |
|
the health piece. We know that redline communities and poor |
|
people in this country face multiple health threats from |
|
buildings. Our public school and public housing infrastructure, |
|
for example, has major issues with mold, asbestos, and other |
|
toxins. |
|
What do we know about the health benefits of deep energy |
|
retrofits at this point, and what do we still have to learn? |
|
Can you paint a picture for us for how life could be better in |
|
a highly efficient, zero-carbon home or workplace? |
|
Dr. Esram. Well, thank you for the question, Chairman |
|
Bowman. What we know, decades of scientific research have |
|
proven the impact of a built environment on the human circadian |
|
rhythm, immune system, cognitive function, and task |
|
performance. There are plenty of literature. But what we don't |
|
know is how to fully integrate these nonenergy benefits with |
|
technology and strategy development that speaks to the |
|
consumers and the investors. And there are no standard methods |
|
to quantify and monetize these benefits in a trustworthy way |
|
for consumers. |
|
A quick example is when we buy organic food, we trust USDA |
|
(United States Department of Agriculture) organic stamps. |
|
There's a standard way to measure these nonenergy benefits for |
|
organic food and procedure, but we don't have those for |
|
buildings, for healthy buildings. |
|
Just to--yes, that's my answer in a simple way. Thank you. |
|
Chairman Bowman. Thank you. Thank you very much. |
|
Ms. Patterson, thank you for being with us today. Can you |
|
speak more to the challenges involved in bringing sustainable |
|
building technologies to redlined and low-income communities? |
|
I'm wondering what the CESBS (Centering Equity in the |
|
Sustainable Building Sector) program has learned about what the |
|
main barriers are and what we need to do to surmount those |
|
barriers. How can we scale up weatherization, energy |
|
efficiency, and electrification efforts in low-income and |
|
affordable housing, for example? What do you see as some of the |
|
research and policy needs here? |
|
Ms. Patterson. Thank you so much. So--yes, so there are a |
|
lot of questions in that one question. But--so first definitely |
|
some of the barriers are really just lack of investment in |
|
these communities both in--not only in terms of homes but also |
|
in terms of various structures and communities. And so whether |
|
we have--the challenge I spoke of before with housing in terms |
|
of the historic challenges that resulted in people in the |
|
disproportionate homeownership and so much in terms of these |
|
kind of weatherization, retrofitting, clean energy. All of that |
|
is tied to homeownerships and being able to be--get financing |
|
mechanisms to--equity in one's home. And so that's definitely a |
|
barrier. |
|
In terms of ways that we can shift this is everything from |
|
making sure that there are economic opportunities to bring up |
|
the economic well-being of people so that they can make those |
|
investments and the homeowners themselves but then also |
|
shifting--and so that's from an individual standpoint, but also |
|
shifting as well to communities that have been under-invested |
|
in historically over time, shifting away from this notion that |
|
all of the--what's available in terms of public financing |
|
through property values, which we know just kind of continues |
|
to have the same communities not having the types of resources |
|
that are needed and really thinking about new and innovative |
|
economic ways of lifting all boats because we know that there's |
|
been attempts through--whether it's the opportunity zones or |
|
other types of mechanisms but that have not necessarily been |
|
successful in actually lifting the well-being and the economic |
|
status and what's available in terms of finance for those |
|
communities. So we're actually advancing this transformational |
|
climate finance initiative to significantly invest in these |
|
communities and making sure that, whether it's social impact |
|
investing or municipal bonds or other finance mechanisms, that |
|
they're being brought into communities in ways that aren't |
|
extractive or that actually put communities in the driver's |
|
seat so that these actually work for them. And the Centering |
|
Equity in the Sustainable Building Sector Initiative is a |
|
multi-sector initiative that pushes policies, and that's |
|
everything from renewable portfolio standards to making sure |
|
that building codes are also tied to the economic engine to be |
|
able to ensure that people can be up to the standards we're |
|
putting forward in building codes. So I don't know how much |
|
longer I have to respond, but I'll pause there [inaudible]. |
|
Thank you. |
|
Chairman Bowman. That was perfect. Thank you so much. I |
|
now recognize Mr. Weber for 5 minutes. |
|
Mr. Weber. Thank you, Mr. Chairman. I want to go to you, |
|
Dr. Tour. I want to make sure that what I think I heard, I |
|
heard. Are you with us, Dr. Tour? |
|
Dr. Tour. I am. |
|
Mr. Weber. OK, good. You've got 730 publications, 230 of |
|
those are on graphene, and there was how many patents and how |
|
many companies formed as a result? |
|
Dr. Tour. I have over 150 patent families, but 50 U.S. on |
|
graphene and 90 international on graphene, started 14 |
|
companies, eight of those in nanomaterials. |
|
Mr. Weber. Thank you for that. You said a decade ago your |
|
program was supported 90 percent by Federal funds and then 10 |
|
percent by industry and that that was normal for many research |
|
groups. Then, due to a number of factors, you started appealing |
|
to industry and showing them how your fundamental research in |
|
nanoscience could address some of their technical needs. And |
|
boy, the numbers you just reiterated for us, if they don't |
|
prove you were successful, I don't know what does. |
|
Dr. Tour. Yes. |
|
Mr. Weber. This might surprise some people who think |
|
industry only wants applied research. So, Dr. Tour, can you |
|
talk more about basic research, how it can deliver applications |
|
for industry, and specifically in the building technology |
|
sector, please? |
|
Dr. Tour. Right. So thank you for that, Representative |
|
Weber. I--so what happens is I do basic research. I'm a |
|
scientist primarily. And--but the transition is something that |
|
we need to look for. How do I transition this into something |
|
that can be applied and utilized? And when we make discoveries, |
|
right away, we need to be thinking how can I apply this? And if |
|
we just publish a paper and just think somebody else will apply |
|
it, it just doesn't work. We need to carry that banner several |
|
more steps forward to show them how it might work. I don't have |
|
to bring it all the way to the building, but I have to bring it |
|
to a point where some company is really interested. |
|
So for many years we would license our technology to big |
|
companies, and for one reason or another it would stall in |
|
those big companies. So about 6 years ago I made a categoric |
|
decision we are going to start our own companies, and we're |
|
going to start our own companies and build upon those because |
|
then we can control the technology and push it forward. |
|
And success breeds success. After we were successful with |
|
one or two, then investors started coming and wanting to fund |
|
more and more. And part of that, as I say, you've got to |
|
continue to fund some of the basic work in my laboratory that |
|
will broaden the applications of these, and that then spawns |
|
new companies. So that's basically how we've done it. |
|
Mr. Weber. Well, and that's a great segue because when you |
|
talk about broadening and spawning new companies--as you know, |
|
as a Texan, Houston is an active hub for the oil and gas |
|
industry and also the aerospace industry, and so these large |
|
industries have become interested in your work. And can you |
|
explain that why many of the, quote, building technologies, end |
|
quote, research projects have applicability actually to more |
|
than just the skyscraper construction business? What other |
|
applicabilities does it have? |
|
Dr. Tour. Well, it has to do with roads, as well as |
|
concrete for building, with paints, for wood composites. |
|
Everything is about light-weighting and using---- |
|
Mr. Weber. Right. |
|
Dr. Tour [continuing]. Less materials. And when we use |
|
less materials, there's less carbon dioxide emissions, less |
|
energy put into them, and the processes that we've come up |
|
with--so, for example, just plastics, high density polyethylene |
|
is $2,000 a ton. We put in $30 a ton to convert waste plastic |
|
into graphene that can strengthen a huge amount of plastic with |
|
that. So these innovations have great implications for the |
|
energy industry and for lowering carbon emissions. |
|
Mr. Weber. Sure. Well, I'm just about out of time, so I |
|
will go ahead and yield back, Mr. Chairman, and thank you for |
|
your indulgence. |
|
Staff. Mr. Casten is next. |
|
Mr. Casten. Thank you so much. Always a pleasure in this |
|
panel, Mr. Chairman and to our witnesses. This is a hugely |
|
timely hearing not least because as we sail into thinking about |
|
infrastructure bills, we have some real opportunities I think |
|
to modernize our Federal building stock, public housing, |
|
Federal buildings, the whole scope of that. It's going to be |
|
real important to understand as we are prudent stewards of |
|
taxpayer capital where the biggest bang for the buck is. |
|
So I want to start, Dr. Esram, I wonder in the work you've |
|
done or your colleagues have done at ACEEE, as you're looking |
|
at building efficiency technologies, not the ones of the future |
|
but the ones we can deploy today, what kind of simple payback |
|
can owners realize on these technologies? And if you had to |
|
pick sort of your top three absolute no-brainers that every |
|
building owner should do, what would they be? |
|
Dr. Esram. That's not a very easy to answer question. I |
|
would pick lighting and water heater and probably, you know, |
|
some HVAC (heating, ventilation, and air conditioning) systems |
|
depending on the home location, the building types. Yes, that |
|
is usually--we have done a lot of research. For most of the new |
|
technologies, they pay for themselves. However, they may not |
|
pay fast enough to speak to the consumer's needs. There are |
|
additional benefits as we discussed in the health, resilience, |
|
and productivity. They haven't been really translated in a way |
|
that the consumer will value more with energy efficiency. If |
|
there were a way to quantify, monetize those, I think we can do |
|
retrofitting much faster than we're doing now. |
|
Mr. Casten. OK. Well, would that be a good area for |
|
further research then to try to figure out how to monetize and |
|
understand those benefits? |
|
Dr. Esram. Yes, definitely. |
|
Mr. Casten. OK. |
|
Dr. Esram. We have a lot of pieces of technologies. We |
|
don't know how to build efficient, affordable, healthy |
|
resilient building at the same time. We--they haven't been put |
|
together yet. |
|
Mr. Casten. OK. Well, part of the reason that I started by |
|
asking about proven technologies is that a number of years ago |
|
I had the pleasure of touring the Bullitt Center in Seattle, |
|
Washington, that my friend Denis Hayes has been responsible |
|
for. Many folks on this Committee know Denis is one of the co- |
|
founders of Earth Day. That building uses about 10,000 BTUs per |
|
square foot in a city that averages 90,000, so almost 1/10 of |
|
the energy use with no compromise on the--it's a beautiful |
|
building. It's a wonderfully comfortable place to work, and |
|
they've done it with some low-tech stuff like natural lighting, |
|
with some high-tech stuff like continuous commissioning, and |
|
then really interestingly with the regulatory reforms that they |
|
actually had to work to get the local utility to pay them for |
|
the benefit they provided the utility for reducing peak energy |
|
demand in the city of Seattle. And that building was |
|
commissioned in 2013. There's no reason that technology |
|
couldn't be widely deployed other than perhaps people having |
|
access to capital and what those returns are. Can you tell us a |
|
little bit about the split incentive problem in buildings? Are |
|
you familiar with that term? |
|
Dr. Esram. Yeah, of course. The split incentive meaning if |
|
the landlord is paying for the retrofits and the saving will be |
|
from the tenants because, you know, they are getting the saving |
|
on their utility bills. |
|
Mr. Casten. So when you say that the analysis of some of |
|
the benefits is--some of the--and I'm going to misquote you |
|
here, but some of them have a good payback, some of them don't. |
|
How much would that move if we solve the split incentive? So if |
|
we took a holistic approach, how many of these problems you--or |
|
the challenges you described would go away if we said what is |
|
the total societal savings that would come from these |
|
investments? If we frame it that way, what are--do you have-- |
|
does it change your answer at all? |
|
Dr. Esram. Yeah, absolutely. You know, in the commercial |
|
real estate there's like a 3, 30, 300 rules that on average you |
|
pay $3 dollars per square foot for utilities, $30 for rent, and |
|
$300 for your personnel, your salaries. So if we're able to |
|
quantify all the non-energy benefits and pick a package and the |
|
investors, the building owners, the business owners, the |
|
tenants all have more incentives to work together to upgrade |
|
the buildings. |
|
Mr. Casten. Well, thank you. And I see I'm about out of |
|
time, but perhaps we can follow up afterwards because I think, |
|
again, as we think about making significant investments in our |
|
Federal building stock, we've got a real incentive to save a |
|
lot of money for future generations. But as we think about how |
|
much money we're willing to spend and how to finance that, it's |
|
going to be important that we quantify those things as much as |
|
we can and would welcome the opportunity to work with you and |
|
your colleagues to quantify that as we move forward. Thank you, |
|
and I yield back. |
|
Staff. Ranking Member Lucas is next. |
|
Mr. Lucas. Thank you, Mr. Chairman. I want to thank you |
|
and the Ranking Member. This is a fascinating hearing, and some |
|
really impressive witnesses today. |
|
With that, Dr. Tour, I'd like to turn to you and note that |
|
the Securing American Leadership in Science and Technology Act, |
|
SALSTA as a lot of us like to refer to it, creates a long-term |
|
strategy for investment in basic research and infrastructure to |
|
ensure American competitiveness in industries of the future. |
|
So with that, I turn to you. In your testimony you noted |
|
that you or your companies have received grants from both the |
|
Department of Energy and the Department of Defense and you've |
|
also collaborated with the Army Corps of Engineers. Having |
|
worked with different agencies, do you think a more coherent, |
|
governmentwide strategy on Federal science and research efforts |
|
could assist Federal agencies and the national laboratories in |
|
being a more effective partner to researchers? |
|
Dr. Tour. Yes, absolutely. Anything that can be done to |
|
assist these interactions were we can work across because the |
|
national labs have tremendous facilities, facilities that we at |
|
universities would love to be able to access. And working with |
|
the national labs has been terrific. I mean, we have |
|
representatives here today from Oak Ridge. We've published |
|
papers just recently with Oak Ridge, and we're doing more. And |
|
so to facilitate this and then it's not just--then it goes from |
|
me to then the companies. The companies are able to work, and |
|
so we have both me at Rice University and the companies working |
|
with the Army Corps of Engineers, the companies doing much |
|
bigger projects. We're doing the nano-sized projects, they're |
|
doing the macroscopic projects, but all working toward the same |
|
direction. So whatever Congress could do to streamline that |
|
would be terrific. |
|
Mr. Lucas. And how do you think such a strategy would |
|
impact international competitiveness in next-generation |
|
technologies like building efficiency? |
|
Dr. Tour. Yes, so one of the things that we have done in |
|
the past because we didn't have access in the university to |
|
certain equipment is we've established collaborations with |
|
overseas universities, and that's a shame. I mean, if we could |
|
keep it all here in the United States, that would be much |
|
better. And this has to do with the nanomaterials that are |
|
going to go into making building materials with a lot less |
|
footprint of energy. Like I said, concrete and cement, 8 |
|
percent of all CO<INF>2</INF> emissions. If we could lower |
|
that, it is tremendous. And then the jobs then it all effects |
|
right here. So it would be very good if we could streamline |
|
that and have to be less dependent on the excellent access to |
|
equipment, particularly in Asia. |
|
Mr. Lucas. Dr. Tour, our legislation I mentioned, SALSTA, |
|
also aims to expand our American STEM workforce pipeline and |
|
its investment in infrastructure needed to maintain domestic |
|
research facilities. So I'd ask you the following. What role |
|
does infrastructure--and by that I mean world-class |
|
laboratories, top-notch instruments, collaboration, |
|
collaborative user facilities--have in attracting and keeping |
|
researchers here in the United States? |
|
Dr. Tour. This is a very big deal. We have a brain drain |
|
going on right now because students are going back to their |
|
home countries rather than becoming professors in the United |
|
States, which they have traditionally done, because of the lack |
|
of equipment and the lack of deep support from government |
|
agencies toward academic research. And they are going home |
|
because the packages they can get are much better. I've |
|
testified to Congress before on this same issue, that the brain |
|
drain that is currently happening in the United States is |
|
frightening. Many of these people would have stayed in the |
|
United States had the packages been here, had the equipment |
|
been here. So if we want to keep the first-class people here, |
|
we've got to have the infrastructure to maintain this. |
|
Mr. Lucas. Let me conclude by saying, Ms. Patterson, I |
|
very much appreciate your comments about the Morrill Act of |
|
1862. Hopefully, with time and generational societal change we |
|
are overcoming those deficiencies. |
|
I'm very proud of the efforts made by Congress in 1890 to |
|
create the 1890 land-grant universities and the 1994s. At some |
|
point this is not the right venue we should discuss how we |
|
address the proper funding of the 1890's. I have one of those |
|
in my district, Langston University, an outstanding facility, |
|
but making sure the necessary resources are there so that they |
|
can be fully utilized by people. |
|
With that, I yield back the balance of my time, Mr. Chair. |
|
Staff. Ms. Stevens is next. |
|
Ms. Stevens. OK, great. Well, thank you all so much, and |
|
thanks to our Chairman. And congratulations to him on his first |
|
hearing on a critical topic with some great witnesses. |
|
So our energy efficiency sector employees, you know, just |
|
shy of 2.5 million people according to the latest data that we |
|
have from 2019, and it's projected to grow at about, you know, |
|
3.4 percent year-over-year, and that's according to the |
|
National Association of State Energy Officials and Energy--our |
|
Energy Futures Initiative, yet 91 percent of construction |
|
employers in energy efficiency reported difficulty in hiring |
|
experienced, trained workers. And we certainly hear from our |
|
construction and building trade stakeholders here in Michigan |
|
about our critical workforce shortage, which has been obviously |
|
exacerbated by COVID-19. |
|
And energy efficiency in buildings, as we've been talking |
|
about, has an enormous potential to be a job creator, and we |
|
want to have equity, we want to have inclusion, we want to |
|
target the needs, as our Chairman was discussing. |
|
So, Mr. Hagerman, you discussed the need for workforce |
|
development and training in the energy efficiency sector. You |
|
touched on that. Can we shed some light on the role that the |
|
Federal Government can maintain to help fill this gap, and |
|
could you also comment on programs at Oak Ridge National Lab |
|
that are working to address this need? |
|
Mr. Hagerman. Absolutely. So, first, thank you for that |
|
wonderful question. And as I said in my--with my written and my |
|
oral testimony, jobs are--American jobs are so critical as we |
|
start to decarbonize all the sectors and we actually achieve |
|
energy efficiency savings for the Nation particularly because |
|
these are jobs that are--should be un-outsourceable, right? We |
|
need real people to go in buildings and make them more |
|
efficient. |
|
So let me first to speak to what Oak Ridge is doing. And |
|
of course I think we need to do more. We always need to do more |
|
to train the available workforce that are actually going to |
|
make good on the retrofits and all the other activities that |
|
American companies want to pursue. But we do three main things. |
|
One, we have the Oak Ridge Institute, which is a collaboration |
|
with University of Tennessee, where we're trying to grow the |
|
talent population and pool, pipeline to actually train and |
|
educate the workforce of the future. In one example, a |
|
colleague of mine works in the power electronic space. That's a |
|
space where I think that we need to spend a little bit more |
|
time and focus on actually making sure that Americans lead the |
|
intellectual pursuits in power electronics and advanced power |
|
electronics. It was a little concerning in the renewable space |
|
we saw Huawei as the No. 1 seller of solar---- |
|
Ms. Stevens. Right. |
|
Mr. Hagerman [continuing]. At one point in time, right? So |
|
we need to---- |
|
Ms. Stevens. Yes, we need this to be American jobs. No, |
|
and, Ms. Patterson, thank you so much for your testimony. I |
|
wanted to give you back some of your time because I know 5 |
|
minutes goes quick. But you say the lack of representation in |
|
certain energy efficiency fields specifically that only .3 |
|
percent of architects are Black women. So let's talk about this |
|
a little bit more. What are some ways--and, you know, I've been |
|
working on this in my career before I got to Congress, very |
|
focused on this now, but what are ways in which we can target |
|
and train workers particularly in communities of color in an |
|
appropriate and significant way? |
|
Ms. Patterson. Thank you so much for that question. Yes, |
|
so we have been working with Department of Energy specifically |
|
and through the Solar in Your Community Initiative and also |
|
through their Solar Energy Technology Office around how do we |
|
start to deploy both kind of the skills and resources to |
|
support kind of skills building, as well as providing resources |
|
for entrepreneurs and vendors so they can be competitive in |
|
this market. |
|
So one of the--so everything from policymaking like local- |
|
hire provisions and disadvantaged business enterprise |
|
provisions that are tied directly to these contracts I think is |
|
critical so that [inaudible]--and then also ways that we can |
|
look at the investments in--I think, as we talked before, in |
|
terms of the HBCUs (Historically Black Colleges and |
|
Universities) and other educational institutions to ensure that |
|
we have a pipeline, the good kind of pipeline in terms of |
|
pathways for folks to enter into these professions are critical |
|
as well and really working closely with those institutions to |
|
help to build. And then also the skills training in terms of |
|
vocational training but it's not necessarily through the |
|
university, but those--making pathways like we--we're working-- |
|
we're starting a Solar Vets Initiative to help to train--that's |
|
just--that's tied to the solar that's resources that are |
|
available that we'd love to see--I think they've cut back on |
|
their funding. We'd love to see that reignited and fully funded |
|
in terms of the Solar Vets Initiative, as well as really some |
|
funding that would target women. We did a project that was |
|
doing---- |
|
Chairman Bowman. Ms. Patterson, just finish up your last |
|
thoughts. Sorry about that. |
|
Ms. Patterson. Yes, it's no problem. So working with |
|
things like grid alternatives [inaudible] and others that were |
|
specifically trying to train women and making sure that we have |
|
funding [inaudible]--thank you. |
|
Ms. Stevens. Thanks. I yield back, Mr. Chair. Thank you. |
|
Staff. Mr. Baird is next if he's available. |
|
Mr. Baird. I am. |
|
Staff. OK. You may proceed. |
|
Mr. Baird. Thank you, sir. You know, I really appreciate |
|
your having this hearing, Mr. Chairman and Ranking Member |
|
Weber. Now, I see our Ranking Member Lucas is on here, too, and |
|
he's always got an interesting perspective. |
|
But the thing that I was very interested in, Dr. Tour, I'm |
|
going to start with you because I found this carbon sink and |
|
the materials you mentioned kind of fascinating. And you know |
|
we have a tremendous capability at DOE with the computer |
|
capacity that we have to be able to advance this kind of |
|
technology. So I hope we can see a strong future partnership |
|
between the industry and our national labs and all this kind of |
|
research. But I would just like for you to elaborate on using |
|
the material to make cement, airplanes, building materials, and |
|
how we get that to our rural communities and some of our more |
|
remote situations. So that's the question. |
|
Dr. Tour. Yes, so thank you, Representative Baird. This is |
|
a real material that is transforming right now. So, like I |
|
said, our production rate is doubling every 9 weeks, so a |
|
single factory within 3 years will be able to produce hundreds |
|
of tons of this per day in about 3 years, and that's the |
|
projection rate. This--the collaborations right now are |
|
happening with companies that are testing these in concrete and |
|
asphalt, and one of those entities is the Army Corps of |
|
Engineers, ERDC, in Mississippi because they have the |
|
capability to do this, and then there's agreements with |
|
companies. We are working with big auto manufacturers taking |
|
their waste plastic because they're responsible now at least |
|
overseas--they're responsible--the American companies that sell |
|
overseas are responsible for their plastic in the E.U. now from |
|
every vehicle, and it's almost 200 kilograms of plastic in a |
|
car. We've converted that into graphene, we've given it back to |
|
them to put it into new plastic that goes into cars, so it's |
|
really a wonderful cycle here. |
|
And the energy savings are real material. This is real |
|
material going into then construction, concrete, wood |
|
composites with wood manufacturers, so this is really beginning |
|
to transform this. And this is one of the things that's been |
|
permitted by keeping this in a small company where I can help |
|
to control this and say, no, we got to get this into these |
|
products, as well as small companies contacting me that want to |
|
deploy this. I say, OK, we're not in the big scale deploying |
|
right now, but that's going to come within a few years and we |
|
marked down their names and we want to see this deployed. |
|
Mr. Baird. Fantastic. I find that extremely interesting. |
|
And with the ag background, some of the materials that you |
|
could have access to, including forest products that can be |
|
converted into this kind of material is of great interest to |
|
me, so I'm glad to see the research that we do, the research |
|
that you've done making that kind of progress. |
|
If any of the other witnesses would like to or care to |
|
make a comment, feel free to do so at this time. I got about a |
|
minute and 25 seconds left. |
|
Mr. Hagerman. I--so this is Joe Hagerman with Oak Ridge |
|
National Lab and, you know, partnerships are a key to our |
|
science, right? They are one of the fuels for our science. In |
|
our BTRIC user facility we have 19 active CRADAs (cooperative |
|
research and development agreements) where we're actively |
|
working with companies, and companies seek us out. And DOE has |
|
just announced or has announced a technical collaboration |
|
program that companies can use and leverage Oak Ridge to solve |
|
their problems, and I think that's a wonderful way that we can |
|
augment U.S. companies and make them get to the results that we |
|
know they can have. |
|
Mr. Baird. Yes, I think it's important, too, that our |
|
national labs--I'm very pleased that they're able to do some of |
|
the basic research sometimes that the industry cannot really |
|
justify, that that then leads into the kinds of things we're |
|
talking about here, so thank you very much. And I yield back. |
|
Dr. Jackson. Can I add as well? |
|
Mr. Baird. Sure. |
|
Dr. Jackson. Yes, so I'd like to add as well, coming from |
|
a background of being a general contractor before going into |
|
the national lab, really understanding that most general |
|
contractors are small and don't have the research budgets, and |
|
so the role of DOE and a national lab being able to provide |
|
research and through programs such as Building America where |
|
Building America is actually taking technologies that are |
|
developed in the lab and working with builders boots on the |
|
ground to actually deploy this, as well as retrofit |
|
contractors, and so that's just one example. Better Building is |
|
another. And then the ABC, Advanced Building Construction, is |
|
yet another initiative that is intending to do that, to be that |
|
venue, and now we can develop science, take science, develop it |
|
into products and bridge that gap, so those contractors like |
|
myself back in the day could help get technologies developed |
|
and deployed. |
|
Mr. Baird. Excellent point, excellent point. I yield back. |
|
Thank you. |
|
Staff. Ms. Bonamici is next. |
|
Ms. Bonamici. Thank you, Chair Bowman and Ranking Member |
|
Weber. Thank you to all of our witnesses for joining us today |
|
and for your expertise. |
|
I know that residential and commercial buildings--we know |
|
this--are notoriously challenging to decarbonize. But to |
|
address the climate crisis, we need to meaningfully repair and |
|
rebuild our Nation's infrastructure in a resilient and |
|
sustainable manner. So last year I joined my colleagues on the |
|
Select Committee on the Climate Crisis. We released a bold, |
|
comprehensive, science-based climate action plan to reach net |
|
zero emissions no later than midcentury and net negative |
|
thereafter. Our plan includes many policies to eliminate |
|
emissions from new buildings by 2030, increased homeowner |
|
incentives for energy-efficient affordable housing. And I look |
|
forward to working with my colleagues on this Subcommittee and |
|
the Full Committee to advance these policies. |
|
Dr. Esram, I represent a district in northwest Oregon. I |
|
know you're in the Pacific Northwest as well. In the district I |
|
represent, the Orchards, which is--was completed in June of |
|
2015, at the time was the largest certified multifamily Passive |
|
House building in North America. They anticipated in its 57 |
|
units to have a 90 percent energy reduction for heating and 60 |
|
to 70 percent overall savings in energy use compared to a |
|
typical building of its size. Not far from the Orchards is the |
|
headquarters of the First Tech Federal Credit Union, which is a |
|
five-story 156,000 square-foot building built of cross- |
|
laminated timber (CLT). |
|
So in northwest Oregon the industrial sector is turning to |
|
mass timber as an alternative to steel and concrete, and cross- |
|
laminated timber, when harvested using sustainable forest |
|
management practices, can sequester and store massive amounts |
|
of carbon dioxide. There are still questions about the |
|
lifecycle assessments of CLT, but the material raises the |
|
possibility of storing massive amounts of carbon in buildings |
|
for decades or perhaps in perpetuity. |
|
So, Dr. Esram, in your testimony you noted that the R&D |
|
gap in our understanding of lifecycle carbon--that there is an |
|
R&D gap. So what initiatives could the Department of Energy's |
|
Building Technologies Office advance to better address embodied |
|
carbon and operational carbon emissions in building materials, |
|
equipment, and construction processes? |
|
Dr. Esram. Well, thanks for the question, Congresswoman. |
|
The most-needed R&D gap is a standardized way to calculate the |
|
lifecycle impact of all these materials and also from a |
|
holistic perspective to consider building as an integrated |
|
entity, not just pieces, you know, the concrete [inaudible]. I |
|
think we need to think about what is a target, how to |
|
standardize it, and also give innovation or freedom to the |
|
architect, to the builders to create low-embodied carbon |
|
buildings and not just really at a surface level and go one |
|
step deeper, standardization, and the most holistic view of |
|
looking at embodied carbon buildings. |
|
Ms. Bonamici. And what difference would it make if we had |
|
those standards? |
|
Dr. Esram. I think that will make the industry being more |
|
innovative to actively think about how can they create building |
|
products that--increase--include multiple benefits for the |
|
society and for the building owners and for the building |
|
occupants because currently our so-called lifecycle analysis is |
|
too narrowly defined on the economic payback of certain |
|
technologies or constructions. It's just---- |
|
Ms. Bonamici. That's helpful. And I don't want to cut you |
|
off, but I really want to get a question in to Ms. Patterson. |
|
And, Ms. Patterson, Portland State University recently released |
|
a study demonstrating how historically racist redlining housing |
|
policies in northeast Portland have exacerbated the effects of |
|
warming temperatures and poor air quality and we--for Black |
|
people and people of color. Extreme heat events are expected to |
|
increase in frequency and intensity because of the climate |
|
crisis and, as a result, these same historically underserved |
|
neighborhoods will face health risks of increasing |
|
temperatures, higher energy bills, and inequitable access to |
|
green spaces. |
|
And we know that many Federal programs like the DOE's |
|
Weatherization Assistance Program can't meet current demands. |
|
So what does this mean for our BIPOC communities and how can |
|
Congress better support innovative residential weatherization |
|
and energy practices, particularly for frontline households? |
|
Ms. Patterson. Thank you so much. Yes. So I think one key |
|
strategy is to really think about spending priorities across |
|
the board and think about models that are multi-solving so that |
|
we don't just think about energy retrofits that are just |
|
focused on energy reference retrofits through the Department of |
|
Energy but we think about how we do energy retrofits that are |
|
tied to other--you know, that are financed through health |
|
funding because we know that having better indoor air quality |
|
and better temperature moderation and so forth are better for |
|
multiple reasons and also tied to resources from Department of |
|
Labor. So we've put together kind of cross-sector packages in |
|
order to be able to truly fund these and recognize that it's |
|
not just about providing one single thing, but it's about |
|
lifting the quality of housing and the quality of health and |
|
well-being and think about how each of these sectors contribute |
|
to that goal. So I think really multi-solving is the key--key |
|
term here and therefore multisector or multi-funding |
|
approaches. |
|
Ms. Bonamici. Great, thank you. And I see my time is |
|
expired. I yield back. Thank you, Mr. Chairman. |
|
Staff. Mr. Garcia is next. |
|
Mr. Garcia. Thank you, Mr. Chairman. Chair Bowman and |
|
Ranking Member Weber, thanks for pulling this together. This is |
|
actually very interesting discussions here. I want to thank all |
|
of our guests and actually congratulate you all for your |
|
achievements and your successes in being leaders in your |
|
respective fields. |
|
I've got two questions. The first is for Dr. Tour and the |
|
second is for Dr. Jackson. Dr. Tour, this graphene discussion |
|
is very interesting. When I saw the writeups for this, I was |
|
doing some homework yesterday in preparation for today, and |
|
what I was looking at initially was whether or not the use of |
|
graphene would become a potential environmental risk like what |
|
we've seen with PFAS creeping into our water tables. I'm sure |
|
you're familiar with what PFAS is, the polyfluoroalkyl |
|
substances. We have a contamination problem in California with |
|
PFAS getting into our waters. And while I was doing that |
|
research, I was reading that graphene is actually as it is |
|
effectively an allotrope of carbon, right? It's a derivative of |
|
sort of an activated carbon. And I was reading articles where |
|
graphene may actually be used to remove PFAS as a potential |
|
filtrate opportunity. Have you seen any research or done any |
|
research to where the use of graphene within water filtration |
|
systems can help mitigate our PFAS problems that we're seeing |
|
in some of our local communities? |
|
Dr. Tour. Yes, I don't know particularly with PFAS, but I |
|
know that graphene, these carbon materials are indeed being |
|
used for water filtration. In fact, I have a company that's |
|
actually doing that, using graphene in water filtration |
|
systems. And so--and the thing about graphene is it's already |
|
naturally occurring. If you have graphite in a riverbed, it's |
|
shearing off slices of graphene. It's already naturally |
|
occurring, and that's what makes it all the more attractive in |
|
that it's a naturally occurring material, hard to access, but |
|
for water filtration, the PFAS problem, there are other ways |
|
that we're addressing that. And actually my group is addressing |
|
particularly that problem, so I know something about that. And |
|
we've just recently gotten some grant money to do that through |
|
the Department of Defense to try to address specifically that |
|
PFAS problem. |
|
Mr. Garcia. If it's OK, maybe you and I can take it |
|
offline, but I'd love to connect you with our local water |
|
districts here in my district in southern California. They're |
|
struggling with this right now, as many are, but they're on the |
|
precipice of making very significant investments, and I just |
|
want to ensure they're looking at all options before we go too |
|
far downrange. A lot of Federal assistance going into those |
|
types of programs as well, as you know, so I would love to be |
|
able to connect you offline if we can with some of our folks on |
|
our end. |
|
Dr. Tour. I would be glad to. |
|
Mr. Garcia. Thank you, sir. Dr. Jackson, it's hard to |
|
believe that solar power for residential applications has been |
|
around for, what, 30 years now, maybe even a little bit longer. |
|
Can you talk to us a little bit about the generational shifts |
|
in solar power? I know the cost curve is coming down. You know, |
|
it's Moore's law really, right? It's double-capacity, half- |
|
price every, what, 5 or 6 years. We're seeing that real-time. |
|
Is it just an improvement in efficiencies and costs, or are |
|
there other sort of revolutionary increments in terms of the |
|
technology? I know the integration of solar into roof tiles now |
|
is a new thing, but can you talk to us about how the solar |
|
industry is actually--what is the state-of-the-art and why is |
|
that so important right now? |
|
Dr. Jackson. So I think that's a great question. I think |
|
we've seen some of the trends because of multiple things. I |
|
think it's a multifold, one being the materials. We have been |
|
able to go from some of the traditional semiconductor-type |
|
materials that we used 30, 40 years ago, and now we're actually |
|
using even some of organics so even one of the things that's |
|
been--really NREL has been leading on is perovskites (PV) is |
|
one where you can basically paint it on. There's YouTube videos |
|
of painting on of PV device. |
|
And so one of the things--then the next step is what we do |
|
as we continue to advance the curve is the soft costs, the cost |
|
of integration, because if you make a supercheap material but |
|
it takes a lot integrate it, then the overall effective cost is |
|
still high. So that's been coming down as well. |
|
Then finally where I see this going is now what we're |
|
seeing--actually, it was a Nature Communications paper last |
|
year where we took those advances in perovskites and other |
|
types of materials and said what if you actually integrated |
|
those into your window--into your building facade? So now you |
|
can see that window that actually is glazing. You can see out |
|
of it, but by innovating some technology that we have, you can |
|
make it where it switches, where it's a clear window when it's |
|
kind of the light it isn't as clear, but then when the sun is |
|
readily available, it can actually serve as a glaze to help |
|
with glare while also collecting solar. So you have a--so it's |
|
taking that perovskites, those types of innovations and |
|
incorporating into traditional facade and windows to be able to |
|
take solar innovation to the building envelope to the next |
|
level. |
|
Mr. Garcia. That's fantastic. I can go on for hours on |
|
this stuff. Thanks, guys, for sharing, very interesting |
|
technologies. And I yield back. I'm out of time. Thanks, guys. |
|
Staff. Ms. Ross is next. |
|
Ms. Ross. Thank you, Mr. Chairman, and thank you for |
|
having this be our first hearing. It's really fascinating. |
|
I want to talk a little bit about your initial theme for |
|
the hearing, and so--which is how do we get some of these |
|
technologies that are good for our environment and good for |
|
people's health in affordable housing. And right now in my |
|
district I have a--I'm from the Research Triangle area. It's a |
|
growing area. And we are coming up against a real battle to get |
|
more affordable housing. At the same time, old--what used to be |
|
called housing projects are being torn down because they are-- |
|
they're past their useful lives and the living conditions are |
|
not as good, and we're replacing them. |
|
And so I'd love to know from any of the panelists where |
|
there are good examples of sustainable, healthy, affordable |
|
housing projects in this country or in other countries so that |
|
when we build again, we build in a way that all residents get |
|
the health benefits, get the energy-efficiency benefits, and we |
|
get the environmental benefits. So to anybody, it looks like we |
|
have a few people who want to jump in. Yes. |
|
Mr. Hagerman. So this is Joe Hagerman with Oak Ridge. I |
|
can talk a little bit about our work with Clayton Homes, so |
|
Clayton Homes is the largest affordable housing manufacturer I |
|
think in the Nation. We're working with them to apply some of |
|
the connected-community principles into their manufactured |
|
housing and make those homes safer, more efficient, and |
|
healthier in terms of indoor air quality. And this is really |
|
about adding controls into their normal product and making |
|
those things world-class and really taking the lessons learned |
|
from our previous projects in Alabama, Georgia, and with EPRI, |
|
the Electric Power Research Institute. |
|
Ms. Ross. And as a follow-up, how can we in Congress |
|
create incentives to do that? So, you know, some people who are |
|
in the affordable housing business are in it as a business. |
|
Other people are in it because they really care about the |
|
residents. Are there any triggers or incentives that we in |
|
Congress could provide to have that--these practices--best |
|
practices be more widespread? |
|
Mr. Hagerman. Oh, absolutely. So another project we have |
|
with the Knoxville Community Development Corporation, they're |
|
actually actively decarbonizing their buildings, and they-- |
|
those are actually their words, right? And so I think we as a |
|
lab have really learned a lot from that in terms of seeing |
|
retrofits, and as you talk about best practices for retrofits, |
|
they need to pivot to see those as decarbonization events |
|
because it would make the house healthier for the homeowner and |
|
they'd pay one less bill at the end of the day as well. So I |
|
think those incentives to really kind rethink retrofits is a |
|
whole--and incentives to help decarbonize or make the |
|
justification to decarbonize would help. |
|
Ms. Ross. Thank you. Does anybody else know of examples |
|
around the country or around the world, any of the other |
|
panelists? |
|
Dr. Jackson. I'll give some--I'll give an example |
|
[inaudible] because I think one of the things we have to be |
|
[inaudible] to ensure that we approach the affordable housing |
|
challenge particularly with retrofits. Those are distinctly |
|
harder. As the Chairman mentioned, in--because--in New York |
|
we've seen--the New York Times, we've talked about like some of |
|
the urban heat island effects, and so a lot of times in |
|
projects you see the actual temperature change--the temperature |
|
dynamics in those environments are different, so we have to |
|
think through them differently to make sure that we have the |
|
right solution for the right application. |
|
And so a--we've seen in Europe--some of the things they've |
|
done in Europe is they use modular construction and actually |
|
replace the whole building facade. Now, those are some of the |
|
things that the Advanced Building Construction Initiative |
|
through the DOE's funding were actually trying to say how can |
|
we take the best from those things like we--in Energiesprong |
|
that's done in Europe and say what does that look like or what |
|
is a modular-type approach that can be used here or a panelized |
|
approach and say for these types of affordable construction, |
|
how do we do the best thing for that? Because just because it |
|
worked in a market rate or advance market community doesn't |
|
mean it's going to work in an affordable community. And I think |
|
that's the--that's the challenge that we face is if we do that, |
|
we have--we end up with a less optimal or a less correct |
|
solution for those communities that actually need more |
|
investment. |
|
So to your question of what we can do, I think we need to |
|
have a very focused effort on the affordable community so that |
|
we can make sure we're developing the right solutions for those |
|
challenges. |
|
Ms. Ross. Thank you, Mr. Chairman, and I yield back. |
|
Staff. Mr. Feenstra is next. |
|
Mr. Feenstra. Thank you, Mr. Chair and Ranking Member |
|
Lucas. |
|
Before I start, I just want to thank each of the witnesses |
|
for their testimony and sharing their extensive research and |
|
opinions with us. Iowa's 4th District, where I'm from, is no |
|
stranger to leading an energy and environmental design. With |
|
over 65 LEED (Leadership in Energy and Environmental Design)- |
|
certified buildings in my district, northwest Iowa takes its |
|
sustainable buildings very seriously. |
|
Additionally, I'm an original cosponsor on Ranking Member |
|
Lucas's SALSTA's Act that includes an increase in the |
|
investment in the DOE's Office of Science. Their research can |
|
help support the next generation of clean energy and efficiency |
|
and technology. |
|
Dr. Jackson and Dr. Hagerman, I got a question. |
|
Retrofitting existing buildings, which we have a lot of here in |
|
the 4th District, is one way to avoid the embodied carbon and |
|
cost produced from the building and construction process. What |
|
are some of the most cost-effective and carbon-reducing |
|
retrofitting techniques that can be utilized today? |
|
Dr. Jackson. So I'll start. I think the most cost--one of |
|
the things is it's kind of--you know, as an engineer, it |
|
depends. It depends on the application in many instances. So |
|
for the climate, one of the things that you would do is the |
|
building facade to ensure that you get the biggest bang for |
|
your buck because that helps you with resilience, particularly |
|
as we look forward with climate change and making sure that the |
|
building works today but it also works 50 years from now. So |
|
the best you can do is a building facade. |
|
And so now going back to the question Dr. Esram mentioned |
|
before, we need to ensure that we understand the embodied |
|
impact of the materials that go into that facade, and so that's |
|
why we need to continue to advance the research in what--in |
|
embodied energy so that as we do those facade retrofits that |
|
can be done today, they can use the least-embodied energy |
|
approach. So those are--that's one of the most readily |
|
available. |
|
Mr. Hagerman. So this is Joe Hagerman from Oak Ridge, and |
|
I would answer controls and retuning, so controls, if you can |
|
get your controls right, tune up the equipment, you can save a |
|
lot of money, and then once we have controls available, we can |
|
make the schedules fit people's active lives. And then we can |
|
also expose those controls to the utilities so we can start |
|
using and leveraging those buildings as a resource of the grid |
|
to make the grid more resilient, just as we're making your |
|
house more resilient. |
|
Mr. Feenstra. That's very good. This is for anybody. So my |
|
district, we're very high into agriculture production, and so |
|
we maximize the use of our bio-based materials. As an example, |
|
Iowa State Centers for Crop Utilization has worked on projects |
|
like creating adhesives and insulation from crops and crop |
|
byproducts. These can provide a cost-effective alternative |
|
instead of petroleum-based products. Is there a way--or how do |
|
we see that we could expand this research or do you think this |
|
is a good method that we should be spending our time on in |
|
future research? |
|
Mr. Hagerman. So if I could answer that, yes, and, right, |
|
we see a lot of those types of cellular materials going into |
|
the feedstock for our additive manufacturing machines, so I |
|
would encourage you to explore, you know, other uses of those |
|
materials, too, especially in the advanced construction kind of |
|
industry and this 3-D printed world we're about to live in. |
|
Mr. Feenstra. All right. Well, thank you so much, Doctors. |
|
Mr. Chair, thank you, and I yield back. |
|
Chairman Bowman. Thank you very much. Before we bring the |
|
hearing to a close, I want to thank our witnesses for |
|
testifying before the Committee today. The record will remain |
|
open for 2 weeks for additional statements from the Members and |
|
for any additional questions the Committee may ask of the |
|
witnesses. |
|
The witnesses are excused, and the hearing is now brought |
|
to a close. We are adjourned. |
|
[Whereupon, at 2:35 p.m., the Subcommittee was adjourned.] |
