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