Funding Type: Scaling Up the Next Generation of Building Efficiency Packages Funding Opportunity Announcement (DE-FOA-0001518)

Project Objective

This project will validate the heating and occupant-based savings in existing multifamily units using “smart” and connected terminal unit controls, such as wireless thermostatic radiator valves, as part of an integrated energy management system.

Project Impact

This technology works across two building systems to improve the building’s energy efficiency. If widely adopted, the radiator valves and energy management system demonstrated in this project could achieve savings up to 190 TBtu per year, representing a 50% reduction across the multifamily and multitenant building sector.
