To Decarbonize Buildings, Think Like An Entrepreneur

This article by IMPEL Program Director Reshma Singh was published in Smart Cities Dive.

Cities, states, labor and industry recently announced that they’re teaming up with the Biden administration to launch the Building Performance Standards Coalition, a first-of-its-kind partnership dedicated to slashing the building sector’s energy use and greenhouse gas emissions to create healthier, cleaner, more affordable buildings and jobs that pay well.

In this decisive decade for climate action, the effort couldn’t be more timely. It’s critical to remember that even our best, most innovative ideas won’t have any impact if they never reach the market. 

Buildings and construction have immediate climate impacts as well as lasting market and societal implications. They’re responsible for about 40% of energy-related global greenhouse gas emissions, with operations accounting for 28% and embodied emissions from construction and materials like steel and cement accounting for 11%. Thus, well-funded building innovation supported by smart climate policy is critical for the transformation of the built environment.

IMPEL Announces New Mentor Advisory Panel, Moves COP26 Mid-Century Climate Goals to This Decisive Decade 

The policies and politics of climate change are at stake at the COP26 Summit this week, with global leaders committing to net zero by mid-century.  At IMPEL, we believe that this decade is critical for climate action. This can be done in part by accelerating building technologies that are ripe for near-term impact. 


To guide IMPEL’s  building Innovators who can make an impact in this decisive decade, we are proud to announce the IMPEL Mentor Advisory Panel that adds a new depth of expertise to our program. These industry leaders bring a broad base of tech-to-market knowledge to IMPEL, and will help Innovators navigate over the “Valleys of Death” as often experienced on the path to commercialization. Mentor learning forums include group and one-and-one mentoring sessions, IMPEL’s Reverse Pitch event, and potential access to the Mentors’ powerful pipelines and networks. 


The twenty mentors joining IMPEL this year come from boutique and global investment groups, government agencies like the Department of Energy (DOE), Department of Defense (DOD), and the National Lab network, and the private sector.

IMPEL Your Building Solutions to Scale

World-class leaders from the worlds of investing, technology, the public sector, and business are lending their expertise to the Department of Energy’s 2022 IMPEL accelerator, with a mission to speed commercialization of technologies that slash buildings’ carbon footprint — an essential and urgent aspect of curbing climate change. 

“In the U.S., buildings are responsible for 40% of greenhouse gas emissions – more than any other sector,” said Dr. Carolyn Snyder, Deputy Assistant Secretary for Energy Efficiency at DOE. “President Biden has set a goal of cutting U.S. emissions in half by 2030 compared to a 2005 baseline, and meeting that target will require dramatic improvements in building energy efficiency and rapid deployment of grid-integration and clean-energy technologies for buildings. IMPEL is helping some of the most exciting, advanced building technologies get into the marketplace, where they can help slash emissions.”  Read the entire article at the DOE's site here!

IMPEL Webinar 2: Delivering on the Promise of Healthy, Energy Efficient Buildings

Since the early 2000s, the drive for improved energy efficiency, sustainability, survivability and occupant health has caused forward-thinkers to question “How we can deliver on the promise of healthy, affordable, energy efficient buildings without changing the way we build?” It was then that the industry began experimenting with designs for continuously insulated, modular, prefabricated building panels. This deep dive into the many challenges that prefabricators must overcome if they are to succeed in transforming the way we build. David shares many lessons learned and identifies some remaining obstacles. This webinar is especially relevant for the two IMPEL teams focused on building materials.

IMPEL Elevator Pitch Session

Developing a succinct pitch seems simple but actually takes a lot of brainpower and is best done with outside feedback. In this video, Berkeley Lab and Cyclotron Road researchers practice pitches for promising technologies with coaching from experienced entrepreneur Christina Ellwood. The intent of the IMPEL channel is to foster a culture of market awareness within DOE labs to help direct future research, and develop innovative lab ideas into teams, assets, and source funding. This can help to drive high impact, industry-relevant technologies from early stage R&D to private sector uptake. This work is supported by the U.S. Department of Energy.
