While commissioning of MEP building systems has been around for many years, Building Enclosure Commissioning (BECx) is relatively new to the construction industry. This presentation will provide an outline on the practice of BECx and its benefits with real world case studies. It will begin by walking through the fundamental building science principles pertaining to heat and moisture movement through building enclosure assemblies, as well as describe the function and order of importance of the primary environmental control layers (water, air, vapor and thermal).
The building science principles will serve as foundation for understanding anticipated building performance and what is expected for high performance buildings today while comparing to what was required historically. The presentation will then dive further into the various approaches in the industry today like LEED v4.1 and ASTM E2813, focusing on the key activities performed during each construction phase. Each stage of the BECx process will be thoroughly described including the typical deliverables (e.g., BECx Plan/Record, BECx specifications examples, design peer reviews, construction observation, item tracking log, functional performance testing, etc.).
Learning objectives:
- Explore building enclosure history and design principles.
- Explain BECx requirements.
- Summarize BECx deliverables.
- Describe BECx functional performance testing.
