ASHRAE STANDARD 202-2024

ASHRAE Standard 202- 2024 outlines the Commissioning Process for mechanical, electrical, plumbing, control, data center, process, building monitoring, and renewable energy systems in the project scope. It is a systematic process that begins in the early design phase and continues through the warranty or post-occupancy phase. Along with the ASHRAE Standard 202-2024 requirements, teams must also comply with incremental LEED AP ID+C requirements.

EAp3: Fundamental Commissioning, Table 1 provides a detailed comparison of the ASHRAE Standard 90.1 commissioning requirements for the prerequisite and the ASHRAE Standard 202 requirements for Enhanced Commissioning of MEP systems. The table also provides timing for each task.

TIMING OF CXP ENGAGEMENT

ASHRAE 202 requires CxP review of the OPR, and initial development of the Commissioning Plan during pre-design, necessitating very early engagement of the CxP in the design process. If the CxP is engaged after pre-design, alternative measures must be taken to ensure alignment with the intent of the Standard 202 timeline.

Examples of acceptable CxP engagement after pre-design

• Portfolio applications where the OPR and Cx Plan at the predesign phase are similar to other projects.

• A qualified employee of the owner provides the initial review of the OPR and initial draft of the Cx Plan and CxP is designated early in design development to continue the analysis.

COMMISSIONING SCOPE

The enhanced MEP commissioning scope must comprehensively address alignment with the OPR, expanding the focus beyond energy and GHG emissions to address water efficiency, air quality, and thermal comfort. Commissioned systems must address all the following systems or components in the project scope of work and any interconnection with base building systems.

• Mechanical . HVAC and refrigeration, including any process heating or cooling systems in the project

• Electrical . Lighting, receptacle power

• Plumbing . Indoor fixtures, SWH, pool equipment, etc.

• Data center . Electrical, cooling, humidity. Identify a mechanism for evaluating whether server equipment efficiency targets are met.

• Building monitoring . Include all monitoring systems required by ASHRAE 90.1, as well as any EIS and Fault Detection and Diagnostic (FDD) systems referenced in Option 2.
