Research in the Building Envelopes Program (BEP) focuses on improving not only the systems that make up the roofs, walls and foundations of buildings, but also the insulating materials that these systems contain.  We are interested in the ways that heat, air, and moisture travel through the building envelope and the effects that various building materials have on energy consumption.  The goal of this research is to identify energy-efficient building materials and envelope systems that will be adopted by the U.S. building industry.
