Building Envelope

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 Solutions 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.

Partner List

Through the Better Buildings Alliance, over 200 public and private sector organizations across the country are working together to share and replicate positive gains in energy efficiency. 

Featured Solutions

Recent advances in window technologies for both reductions in conduction loses and solar gains can help in tremendous energy savings in commercial buildings.
Exterior walls are the major components of the building envelope. By being a barrier between the interior and the exterior environments, walls need to have features that minimize the energy losses while maintaining durability.
Roofs are another source of building energy loss, but roofing design and materials can help to reduce the amount of cooling required in certain climates by reflecting solar heat rather than absorbing it.
This webinar was the inaugural meeting of the new Building Envelope Tech Team.
