Building Envelope

The building envelope, which includes the walls, windows, roof, and foundation, forms the primary thermal barrier between the interior and exterior environments. With envelope technologies accounting for approximately 30% of the primary energy consumed in residential and commercial buildings, it plays a key role in determining levels of comfort, natural lighting, ventilation, and how much energy is required to heat and cool a building. Members of the Building Envelope Technology Research Team collaborate with DOE's national laboratories to deploy high-performance envelope design solutions for space conditioning load reduction and to facilitate the construction of durable and high performing envelope technologies.

Building Envelope Tech Team Kick-Off Meeting and Open House Webinar

This webinar was the inaugural meeting of the new Building Envelope Tech Team.

  • 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.
