Building Envelope Commissioning and LEEDv4

The Commissioning process has historically attached itself to the active systems, leaving the primarily passive envelope systems undefined and unchecked. However, due to the significant changes in City and State Energy Codes across the US which are addressing envelope design requirements to meet air leakage control and thermal performance targets, a new light has been directed at the importance of commissioning the passive systems. The code changes are requiring designers and contractors to deliver higher performance of their buildings, especially from the building envelope. Building Envelope Commissioning (BECx) is a topic that will enable designers to be prepared for not only the new changes being implemented in LEED v4, but also to stay current on how certain building envelope assemblies perform related to energy performance while ensuring long term durability. Commissioning the building envelope is progressively recognized as an important element in achieving optimal building performance.

Learning Objectives:

1. Understand what Building Envelope commissioning entails – especially related to the requirements in LEED v4
2. Understand the importance of documenting the Building Envelope performance requirements in the Owner’s Project Requirements
3. Understand the impact that building envelope commissioning can have on the energy performance of a building
4. Be able to select appropriate envelope assemblies for commissioning.
