A National Roadmap for Grid-Interactive Efficient Buildings

Since Thomas Edison threw the switch at the world's first commercial power plant in 1882 to power 400 lamps, buildings have consumed the lion's share of U.S. electricity, and today account for three-fourths of the total and even more at peak. Yet, buildings consume power indifferent to grid conditions, blind to the high costs and threats to reliability posed by high peak demand and grid stress; inflexible to opportunities offered by variable, carbon-free renewable power sources; and senselessly missing the smart and connected technology revolution.

Grid-interactive efficient buildings (GEBs) can remake buildings into a major new clean and flexible energy resource. GEBs combine energy efficiency and demand flexibility with smart technologies and communications to inexpensively deliver greater affordability, comfort, productivity and high performance to America's homes and commercial buildings.

DOE'S NATIONAL GOAL FOR GEBs

Triple the energy efficiency and demand flexibility of the buildings sector by 2030 relative to 2020 levels.

Overview of The Roadmap

  • Buildings account for over 70% of U.S. electricity consumption and power sector CO2 emissions.
  • By combining energy efficiency and demand flexibility, grid-interactive efficient buildings (GEBs) can remake buildings into a clean and flexible resource.
  • Achievable national adoption of GEBs could save hundreds of billions of dollars in power system costs, reduce carbon emissions, and relieve stress on the grid.
  • DOE has established a goal of tripling energy efficiency and demand flexibility in residential and commercial buildings by 2030, relative to 2020 levels.
  • To achieve this goal, this Roadmap includes 14 recommendations in the following areas:
    • Advancing GEBs through R&D and data
    • Enhancing and communicating the value proposition of GEBs
    • Empowering users and operators by developing new tools and training workers
    • Using federal, state and local government action to support GEB deployment

The power system value of GEBs was quantified using a sophisticated suite of modeling tools developed by DOE, LBNL, NREL, and Brattle

Buildings account for more than 70% of U.S. electricity use, and a comparable share of power sector CO2 emissions. Improving the way electricity is consumed and reducing the overall amount of electricity consumed in buildings would significantly reduce energy costs to consumers and facilitate the transition to a decarbonized economy.
