Building Enclosure Commissioning Checklist White Paper

As the need for sustainable, energy-efficient structures continues to increase so do the performance requirements for these buildings. Building Enclosure Commissioning, or BECx, is a data-driven, quality assurance process that helps building owners meet or exceed these performance requirements.

BECx consists of a systematic process that utilizes standardized methods for performance tests as set forth by ASTM International and the Fenestration and Glazing Industry Alliance (FGIA; formerly AAMA).

While BECx is often performed on new construction, retro-commissioning offers the opportunity to increase the energy efficiency in existing buildings.
