Standard 90.2 Performance and Flexibility

This presentation describes the performance approach which is the core of 90.2. Performance‐based energy calculation tools have long been elements of building code compliance and beyond code programs. However, these building energy modeling tools have often been varied and inconsistent in their default assumptions, modeling rule sets and calculation approaches. To address these concerns, the SSPC 90.2 has developed very detailed rules governing the energy modeling and analyses necessary to determine compliance. More importantly, 90.2 provides a mechanism by which any residential building design can be easily evaluated against these performance objectives.
