1.   Energy efficiency goals;

2.   Ventilation requirements;

3.   Project documentation requirements, including facility functions and hours of operation, and need for after hours operation;

4.   Equipment and systems expectations; and

5.   Building envelope performance expectations.

(c)        Basis of Design (BOD).



A written explanation of how the design of the building systems and components meets the OPR shall be completed at the design phase of the building project, and updated as necessary during the design and construction phases. The Basis of Design document shall cover the following systems and components:

1.   Heating, ventilation, air conditioning (HVAC) systems and controls;

2.   Indoor lighting system and controls;

3.   Water heating systems and controls; and

4.   Any building envelope component considered in the OPR

(d)       Design Phase Design Review.

2.   Design Review Kickoff. During the schematic design phase of the building project, the owner or owner’s representative, design team and design reviewer must meet to discuss the project scope, schedule and how the design reviewer will coordinate with the project team. The building owner or owner's representative shall include the Design Review Kickoff Certificate of Compliance form in the Certificate of Compliance documentation (as specified in Part 1 Section 10-103.

3.   Construction Documents Design Review. The Construction Document Design Review Checklist Certificate of Compliance shall list the items checked by the design reviewer during the construction document review. The completed form shall be returned to the owner and design team for review and sign-off. The building owner or owner's representative shall include this form in the Certificate of Compliance documentation as specified in Part 1 Section 10-103.

(e)        Commissioning measures shown in the construction documents.



Complete descriptions of all measures or requirements necessary for commissioning shall be included in the construction documents (plans and specifications). Commissioning measures or requirements shall be clear, detailed and complete to clarify the commissioning process.

(f)        Commissioning Plan.



Prior to permit issuance a commissioning plan shall be completed to document how the project will be commissioned and shall be started during the design phase of the building project. The Commissioning Plan shall include the following:

1.   General project information; and

2.   Commissioning goals; and

3.   Systems to be commissioned; and

4.   Plans to test systems and components, which shall include:

A.   An explanation of the original design intent; and

B.   Equipment and systems to be tested, including the extent of tests; and

C.   Functions to be tested; and

D.   Conditions under which the test shall be performed; and

E.   Measurable criteria for acceptable performance; and

F.   Commissioning team information; and

G.   Commissioning process activities, schedules and responsibilities. Plans for the completion of commissioning requirements 'listed in Sections 120.8(g) through 120.8(i) shall be included.

(g)       Functional performance testing.



Functional performance tests shall demonstrate the correct installation and operation of each component, system and system-to-system interface in accordance with the acceptance test requirements in Sections 120.5 130.4 and 140.9.Functional performance testing reports shall contain information addressing each of the building components tested, the testing methods utilized, and include any readings and adjustments made.

EXCEPTION to Section 120.8(g): Healthcare facilities.

(h)       Documentation and training.



A Systems Manual and Systems Operations Training shall be completed.
