Grid-Interactive Efficient Buildings (GEBs)

GEB = Energy Efficiency + Demand Flexibility

The U.S. electric power sector is changing in both challenging and exciting ways. Among the factors influencing this evolution are:

  • The growth of renewable energy sources, and the decentralization of power generation into more distributed energy resources;
  • Technological improvements in energy storage, communications, sensors and controls;
  • Clean energy and climate goals driving efficiency improvements as well as renewables adoption
  • Increasing need for resilience, from climate change, terrorism, etc.;
  • Changes in electric rate structures opening the door– and increasing the imperative – to find new ways for building owners and operators to save money.

All of these factors are driving interest in building and grid integration, a set of strategies, practices and technologies to dynamically shape energy loads, help agencies meet their missions, provide resilience and valuable services to the power grid while saving money for building owners and operators and the taxpayer.

GSA, in partnership with the U.S. Department of Energy (DOE) Commercial Buildings Integration program, released a Request for Information in 2019 seeking technology providers to partner on GEB demonstration projects. In 2020, these two programs selected four Grid-interactive Efficient Building (GEB) technology solutions to be validated in both private sector and GSA facilities.
