The Building Technologies Office research is helping make buildings become smarter about the amount and timing of energy use through the Grid-interactive Efficient Buildings (GEB) Initiative. In addition to improving the energy efficiency of the overall building, this research focuses on making equipment more intelligent through next-generation sensors, controls, connectivity and communication. These capabilities give building occupants more control in managing building comfort and productivity while saving money on energy bills, plus they can benefit the electric grid by enhancing grid reliability and resilience, deferring capital expenditures, and helping balance the supply of renewable generation.

In direct support of the GEB Initiative and Energy Storage Grand Challenge (ESGC), the Building Technologies Office is focused on thermal storage research, development and field validation, seeking to accelerate the commercialization and utilization of next-generation energy storage technologies and sustain American global leadership in energy storage.
