Whole Building Design Guide Federal Green Construction Guide for Specifiers 01810 - 1 http://fedgreenspecs.wbdg.org 11/02/05 Commissioning This is a guidance document with sample specification language intended to be inserted into project specifications on this subject as appropriate to the agency's environmental goals. Certain provisions, where indicated, are required for U.S. federal agency projects. Sample specification language is numbered to clearly distinguish it from advisory or discussion material. Each sample is preceded by identification of the typical location in a specification section where it would appear using the SectionFormatTM of the Construction Specifications Institute. SECTION 01810 - COMMISSIONING SPECIFIER NOTE: This Section includes requirements for commissioning of facilities and facility systems to verify compliance with design, including optimum energy efficient operations. This Section includes requirements for commissioning activities and documentation in compliance with the green building rating system used. For the US Green Building Council (USGBC), edit as per USGBC - LEED™ rating program, including: commissioning activities and documentation for the LEED™ section on “Energy and Atmosphere” prerequisite of “Fundamental Building Systems Commissioning” and commissioning activities and documentation for the LEED™ section on “Additional Commissioning.” For Green Globes – US rating system, edit to include Commissioning Plan – Documentation for Green Globes - US. Other options for systems commissioning may be added as appropriate to Owner’s needs. For example, systems commissioning may address: fire and life safety systems, process chillers, rainwater harvesting, and detailed building control systems. Edit to suit project. PART 1 GENERAL 1.1 SUMMARY A. Section includes: 1. Building commissioning of the following systems: a. HVAC components and equipment. b. HVAC system: interaction of cooling, heating, and comfort delivery systems. c. Building Automation System (BAS): control hardware and software, sequence of operations, and integration of factory controls with BAS. d. Lighting Control System and interface with daylighting. 2. Building commissioning activities and documentation in support of the U.S. Green Building Council (USGBC) LEED™ rating program. a. Commissioning activities and documentation for the LEED™ section on “Energy and Atmosphere” prerequisite of “Fundamental Building Systems Commissioning.” b. Commissioning activities and documentation for the LEED™ section on “Additional Commissioning.” 3. Building commissioning activities and documentation in support of the Building Research Establishment (BRE) Green Globes - US rating system. a. Commissioning activities and documentation for the Green Globes Commissioning Plan – Documentation. B. The Owner, Green Consultant, Architect/Engineer, and Commissioning Agent are not responsible for construction means, methods, job safety, or management function related to commissioning on the job site.

Basis of Design - The basis of design is the documentation of the primary thought processes and assumptions behind design decisions that were made to meet the design intent. The basis of design describes the systems, components, conditions and methods chosen to meet the intent. Some reiterating of the design intent may be included. B. Commissioning – Commissioning is a comprehensive and systematic process to verify that the building systems perform as designed to meet the Owner’s requirements. Commissioning during the construction, acceptance, and warranty phases is intended to achieve the following specific objectives: • Verify and document that equipment is installed and started per manufacturer’s recommendations, industry accepted minimum standards, and the Contract Documents. • Verify and document that equipment and systems receive complete operational checkout by installing contractors. • Verify and document equipment and system performance. • Verify the completeness of operations and maintenance materials. • Ensure that the Owner’s operating personnel are adequately trained on the operation and maintenance of building equipment. The commissioning process does not take away from or reduce the responsibility of the system designers or installing contractors to provide a finished and fully functioning product. C. Commissioning Plan - an overall plan that provides the structure, schedule and coordination planning for the commissioning process. D. Deficiency - a condition in the installation or function of a component, piece of equipment or system that is not in compliance with the Contract Documents, does not perform properly or is not complying with the design intent. E. Design Intent - a dynamic document that provides the explanation of the ideas, concepts and criteria that are considered to be very important to the Owner. It is initially the outcome of the programming and conceptual design phases. F. Functional Performance Test - test of the dynamic function and operation of equipment and systems using manual (direct observation) or monitoring methods. Functional testing is the dynamic testing of systems (rather than just components) under full operation (e.g., the chiller pump is tested interactively with the chiller functions to see if the pump ramps up and down to maintain the differential pressure setpoint). Systems are tested under various modes, such as during low cooling or heating loads, high loads, component failures, unoccupied, varying outside air temperatures, fire alarm, power failure, etc. The systems are run through all the control system’s sequences of operation and components are verified to be responding as the sequences state. Traditional air or water test and balancing (TAB) is not functional testing, in the commissioning sense of the word.
