Join the Building Envelope Campaign
A building's envelope (windows, walls, roof) accounts for approximately 30% of the primary energy consumed in commercial buildings; participants in the Building Envelope Campaign work to improve the performance of building envelopes in both new and existing buildings by setting goals for performance, determining available energy savings, and leveraging technical support from DOE.
