Building envelope

A building’s envelope is its exterior surface. Building envelopes play an important role in determining a structure’s energy efficiency.  By incorporating building envelope improvements into the design or redesign process early on, your company can reduce heating and cooling bills, and potentially reduce or avoid the capital costs associated with new HVAC systems.

For a list of energy efficiency incentives and rebates in your state, visit the State Database of Renewables and Efficiency.
