REVIEW OF TRAINING MATERIALS Facility staff training represents a critical step between the construction phase and postoccupancy. Before or during occupancy, the CxP must review training material to confirm that the training documents meet the training plan and sufficiently address the OPR and BOD. The CxP must also confirm that training occurred.

PATH 2. ENHANCED COMMISSIONING FOR BUILDING ENCLOSURE

Addressing the performance of the building enclosure (also referred to as the building envelope) is as important as the MEP systems. For certain project types, the building enclosure may be the most important factor for continued building energy performance. The credit requires projects to follow a comprehensive process that includes all tasks referenced in ASTM E2947- 21a, Standard Guide for Building Enclosure Commissioning, except Section 7.2.4 and 7.4.3 ASTM Standard E2974-21a .

Building Enclosure Commissioning Provider (BECxP)

ASTM E2974-21a requires a Building Enclosure Commissioning Provider (BECx) to lead and implement the Building Enclosure Commissioning Process. The entity serving as the BECxP performs each required task or delegates it to the appropriate member. The BECxP must be proficient in core competencies for enclosure-related design, construction, and performance.

The CxP and the BECxP can be the same entity or distinct entities.

TIMING OF BECXP ENGAGEMENT E2947-21a, Section 6 describes the pre-design phase tasks, which require BECxP engagement by pre-design. If the BECxP is engaged after pre-design, take alternative measures ensuring alignment with the intent of E2947-21a timeline.

Examples of acceptable BECxP engagement after pre-design

⚫ Portfolio applications where the OPR and Cx Plan at the predesign phase are like 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.

Minimum field testing

At minimum, field testing must include air leakage testing, water penetration testing, and infrared imaging, if applicable to the project scope:
