EA Prerequisite 1: Fundamental Building Systems Commissioning: The documentation for EA Prerequisite 1 may be from the design firm, but the individual acting as the commissioning authority must NOT be responsible for project design, construction management nor supervision. Both the Rating System (p.13) and the Reference Guide (p.95) request that the project "engage a commissioning authority" but does not require an independent firm for the "Fundamental Building Systems Commissioning." However, the Reference Guide elaborates that "This individual must not be responsible for project design or construction management or supervision." (Reference Guide, p.98) EA Credit 3: Additional Commissioning: Tasks 1, 2, and 3 of EA Credit 3 MUST be done by someone representing a firm OTHER than the design firm, while Tasks 4 and 5 may be done by someone from the design firm. The unformated version of the Rating System (p.12) states that "Items 1, 2, and 3 must be performed by someone other than the designer." The formated version of the Rating System (p.18) states that "The above three reviews must be performed by a firm OTHER than the designer." The Reference Guide concurs with the same text and then adds the criteria of "an independent Commissioning Authority" to Tasks 1, 2, and 3 in the submittal language. In the Design Approach section of the Reference Guide (p.146) it elaborates that the intent of the credit is that "The Additional Commissioning Credit ensures peer review through independent, third party verification. There are some provisionary requirements that must be executed by a NON-DESIGN FIRM" Applicable internationally.
