ASHRAE 211-2018 (RA2023)

ASHRAE/ACCA Standard 211 establishes consistent practices for conducting and reporting energy audits for commercial buildings. The standard defines the procedures required to perform Energy Audit Levels 1, 2, and 3; provides a common scope of work for these audit levels for use by building owners and others; establishes consistent methodology and minimum rigor of analysis required; and establishes minimum reporting requirements for the results of energy audits.

 

The 2023 reaffirmation of Standard 211 includes a new Informative Appendix H that establishes consistent practices for conducting and reporting building-level decarbonization assessments for building-related Scope 1 and 2 greenhouse gas (GHG) emissions. The assessment:

 

* Builds on an ASHRAE level 1 or 2 energy audit, with additional evaluation of options to reduce or eliminate on-site fossil fuel emissions, reduce refrigerant emissions, and promote use of on-site renewable energy

 

* Develops a timeline for measure implementation that may consider trigger events such as capital plans for equipment replacement, occupancy turnover, mandated GHG emission limits, market availability of new technologies, and electricity grid improvements
