Performance Anxiety: Confessions from the Building Envelope

How does the design of the building envelope actually perform? This presentation will explore this question and show a comprehensive depiction of building performance as it relates to the building envelope. The innovative strategies presented will analyze the relationship between building envelope assembly, materials, and detailing and the actual performance of the envelope assemblies observed from in-field observations and performance testing. The performance aspects related to the building envelope will address water penetration, condensation, thermal performance, and air leakage.

This will help designers make informed decisions as well as identify and assess areas of high priority earlier in the design process when it comes to meeting project performance goals. With experience working on hundreds of Building Envelope Commissioning (BECx) and envelope testing projects over the last decade, we have seen what works and what doesn’t. Our in-depth discussion of recent architectural concepts will compare design/details versus actual field performance.
