ASHRAE Standard 90.1–Energy Standard for Buildings Except Low-Rise Residential Buildings–was recently overhauled to clarify commissioning requirements for the 2019 edition. An important expansion of typical commissioning work is a review of the design for compliance with 90.1 requirements. The boundaries between a full commissioning project and items required in 90.1 will be explicated. The approach, requirements, and informative material included will be reviewed, along with the cost-effectiveness summary used to support the committee approval. In addition, comparisons to the current version of the International Energy Efficiency Code will be made.

Learning Objectives:

  1. Describe the commissioning requirements in ASHRAE Standard 90.1.
  2. List additional Cx items required by 90.1 not typically included in the Cx process.
  3. Note the differences between Standard 90.1 and the IECC relative to Commissioning required by energy codes.
  4. Describe the difference between normative requirements and informative information in energy codes.
