Envelope Systems R&D

On this page you'll find information about the Building Technologies Program envelope systems research and development and links to current projects.

Envelope systems R&D focuses on establishing thermal performance measurements of well-characterized wall, roof, and foundation systems exposed to realistic field conditions. These measurements are needed to help building designers, owners, and energy officials see the attainable energy and cost savings and the environmental benefits of efficient building envelopes.

To obtain these measurements, envelope systems research involves testing full-scale systems, both in the laboratory and in the field. Extensive modeling is also an important tool in understanding envelope systems performance. To help disseminate these results, DOE—along with the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and several other organizations—has administered a series of Building Envelope Conferences since 1981.
