Building Enclosure Technology and Environment Council

About the Council

The Building Enclosure Technology and Environment Council (BETEC) is celebrating its 30th anniversary. Join us in January for Fenestration: A World of Change, BETEC's Annual Symposium.

BETEC is a voluntary membership council of the National Institute of Building Sciences. BETEC is charged with encouraging optimum energy use of buildings through a better understanding of how overall, complex building components interact with each other and with the environment.


  • To develop a sound technical and economic foundation for optimum energy efficiency in the design, construction, operation, and modification of new and existing buildings through the coordination of research, development, and verification programs;
  • To expedite the use of existing and new technologies in building practice through improved coordination of the activities of the various components of the building community; and
  • To integrate technical programs on fire safety and thermal comfort with the thermal performance of building envelopes.


BETEC brings together a cross-section of public and private building community leaders to solve major energy-related regulatory and technical issues. Its membership is comprised of:

  • Material Suppliers
  • Trade Associations
  • Builders/Building Contractors
  • Code and Standards Organizations
  • Academic Institutions
  • Product Manufacturers
  • Labor Organizations
  • Professional Societies
  • Federal, State, Local Government Agencies/Officials
  • Consumer/Public Interest Groups

Most of BETEC's work is accomplished through its Research Coordinating Committees (RCCs) and Operational Committees. These committees meet on a regular basis to perform studies, develop research, and conduct workshops. Members are encouraged to participate in any of the following:


  • Heat Air and Moisture
