29 projects to receive $46 million from DOE’s 2022/23 BENEFIT funding opportunity to explore building technologies and retrofit practices to reduce energy waste

On Aug. 7, the U.S. Department of Energy (DOE) today announced $46 million for 29 projects across 15 states to develop advanced building technologies and retrofit practices that enable healthier households and communities and reduce energy waste. The Buildings Energy Efficiency Frontiers and Innovation Technologies (BENEFIT) funding opportunity will help advance cost-effective solutions to successfully electrify buildings across the nation while also improving their energy efficiency and demand flexibility. These projects support innovative decarbonization strategies that, when deployed widely and properly, significantly reduce the building sector’s greenhouse gas emissions, eliminate unnecessary or wasteful energy consumption, and reduce strain on the nation’s electric grid.

“Exploring new ways to build and operate America’s buildings is key to cutting harmful emissions and combatting the climate crisis,” said U.S. Secretary of Energy Jennifer M. Granholm in the press release. “With this funding, the Department is providing critical new resources to teams from across the nation to transform game-changing ideas into innovative solutions, creating safer and healthier homes and buildings while cutting energy costs.”

Residential and commercial buildings are the largest energy consuming sector of the U.S. economy, responsible for approximately 40% of the nation’s energy consumption, 74% of its electricity use, and 35% of its total carbon emissions. Estimates indicate roughly one-third, or more, of the energy used by buildings is wasted at a cost of $150 billion annually. Utilizing current technologies and developing new innovations are essential to ensuring buildings across America can quickly and more effectively improve their energy efficiency and decarbonize their on-site processes while advancing environmental and energy justice priorities.

The 29 projects were chosen through a competitive selection process that evaluated their technical merit and likelihood of achieving the DOE’s Building Technologies Office’s objectives. More than half of the 29 projects selected will pursue advancements to improve space conditioning and water heating, which accounts for just over half of all energy use in American homes. The remaining projects will help advance other components affecting residential commercial buildings.

Several of the projects are listed below. For the more information on the projects, visit the DOE announcement “Meet DOE’s Newest Research Projects from BENEFIT 22–23.”
