Americans spend nearly 90% of their time indoors—at the office, out for dinner at a favorite restaurant, in school, or simply living
their everyday lives at home.
But did you know that these same buildings where we live, work, and play consume roughly
40% of America’s total energy use to keep occupants comfortable and productive?
Buildings researchers at the National Renewable Energy Laboratory (NREL) are committed
to transforming America’s homes, offices, businesses, and other buildings into more
efficient, affordable, healthy, and resilient places.
And they are expanding the team to make that shift a reality.
A career in building science at NREL means rethinking the way buildings are designed
and used to lessen the impact on our energy system, without sacrificing affordability,
comfort, or safety. NREL is leading impactful buildings solution at all stages—from
research, development, demonstration, and deployment (RDD&D)—to deliver scalable solutions
for a clean energy economy.
Buildings Researchers Share Their Experience

and said he did not always know his path would lead to a career in buildings research
but recalls there were subtle signs.

“When I was little kid, I liked building things with Brain Flakes and building blocks,”
Jin said.
Stemming from childhood playtime interests, Jin went on to earn a Ph.D. in mechanical
engineering and found applications of his knowledge in control systems in buildings
research. Since joining NREL in 2012, he has contributed to many high-impact projects
in buildings research and innovations.
Jin said his favorite project so far at NREL has been development of the R&D 100 Award-winning smart-home software, foreseeTM. The software can predict future energy consumption in homes, enabling highly accurate
predictions of comfort needs, energy costs, environmental impacts, and grid service
availability by leveraging machine-learning algorithms, advanced data analytics, and
physics-based modeling and simulations to derive data-driven appliance models and
usage patterns.
“The software can provide demand response to the utility and help the homeowner save
energy and utility bills, and also make their home more resilient during an outage,”
Jin explained.
Jin and his team have taken foresee to the affordable housing sector, expanding the
benefits of home automation technology, such as cost savings and convenience, to low-income
residents. As an example, through a partnership with Holy Cross Energy in Colorado, NREL’s foresee technology was used in homes at Basalt Vista, an affordable housing community near
the upscale resort town of Aspen, to house the community’s teachers and county workers.
NREL places energy equity at the center of its mission-driven work, including in buildings
research and deployment. Jin said partnerships and collaboration are essential to
delivering more affordable housing to ensure an equitable and inclusive future of
the buildings industry.
“There’s a housing crisis everywhere in the U.S. right now, and I think the best solution
is to find ways to build homes in a more inexpensive way and make them more efficient
so we can provide more housing to people who need it,” Jin said.

as a nuclear physicist to an expert in equitable buildings design and modeling at
NREL.

With experience in physics modeling and complex data analysis, Clarke sought out NREL
as a place she could transfer her skills into the expanding field of renewable energy
and support the emerging needs for big data and modern modeling solutions.
“My passion is helping people, but in my own nerding-out way,” Clarke said. “Leveraging
a systematic approach gained from my physics background, my research applies a tailored,
holistic approach to truly learn about people’s needs and offset existing injustices
to develop equitable building technology solutions.”
Clarke was selected in the 2016 GEM Fellowship Program, which aims to increase the participation of underrepresented groups at the master’s
and doctoral levels in engineering and science. Since joining NREL in 2019, Clarke
has focused much of her work on equitable building design and deployment for the benefit
of underserved communities.
Clarke said her favorite project so far has been the publication Centering Energy and Environmental Justice in the Buildings Energy Sector, which catalyzed additional work in equity-centric buildings solutions for underserved
communities.
“It allowed me to take a deep dive at understanding how the building energy sector
intersects with environmental justice,” Clarke said.
This approach ensures community members are engaged and involved as experts in every
step of the project, allowing NREL to learn from lived experiences of local community
experts. This allows NREL researchers to incorporate additional equity considerations
and make adjustments in the modeling process to account for actual experiences and
needs.
“Doing this ensures the way in which we’re quantifying [data] and making decisions
using modeling outcomes resonates not only from the technical side but also from the
community’s perspective to meet their needs.”
Clarke has contributed to many equitable, community-centric energy projects at NREL,
including a collaboration with the Black Farmers’ Collaborative where NREL supported planning to incorporate solar panels at Florida farms and churches.
Join NREL’s Buildings Researchers
NREL is transforming energy through integrated building science by leveraging world-class
facilities, unique partnerships, and integrated research capabilities. NREL’s buildings
research is focused across five distinct yet integrated areas to accelerate market
transformation, including energy modeling and analysis; technology innovation; validation,
verification, and de-risking; workforce development; and technical assistance.
Buildings researchers at NREL comes from a wide array of science-based expertise and
experience sectors, bringing diverse perspectives and expertise, to push technology
and innovation to the next level.
To solve the building decarbonization challenge, people of all backgrounds, disciplines,
and perspectives are needed in order to equitably reach a 100% clean energy economy.
“There is nobody who’s not needed in this kind of transition,” Clarke said. “We need
people of every walk of life to be included to help develop and deliver tailored and
equitable solutions.”
Jin echoed this experience, recognizing that his unique skill set and experience in
system automation and control transferred perfectly into his role at NREL.
“I didn’t have much background in buildings, so, when I think about building control
problems, it’s more like thinking outside the box,” Jin explained. “I hope the next
generation of buildings scientists will have an open mind and think outside the box
to help find new solutions and leverage emerging technology, like artificial intelligence,
to help solve building decarbonization challenges.”
Clarke encourages anyone intrigued by renewable energy with a passion to learn something
new to consider a career in the buildings industry.
“Thinking that this kind of work is not part of your skill set is natural but, by
taking that leap of faith, you might find the best outcomes occur when you experience
and challenge the unknown.”
