A building’s envelope is the exterior surface of a building’s construction. A tighter building envelope lowers energy use, lowers heating and cooling bills, and potentially lowers capital costs related to HVAC systems.

As interfaces between building interiors and the outdoors, building envelopes play an important role in the energy efficiency of a building. By incorporating building envelope improvements into the design or redesign process early on, your team can reduce heating and cooling requirements, reducing energy bills and potentially reducing the high capital costs associated with larger HVAC systems.
Most energy consumed in the United States comes from coal, which contributes to smog, soot, and numerous negative health and ecological impacts, including global warming. In addition, coal mining – especially surface mining and mountaintop removal – is devastating some of the world’s most biologically important habitats. Improving your facility’s building envelope may reduce energy loss and cut energy consumption and related impacts.
