The purpose of this guideline is to describe the commissioning process that will ensure heating, ventilating, and air-conditioning (HVAC) systems perform in conformity with design intent. The procedures, methods, and documentation requirements in this guideline cover each phase of the commissioning process for all types and sizes of HVAC systems, from pre-design through final acceptance and post-occupancy, including changes in building and occupancy requirements after initial occupancy. This guideline provides procedures for the preparation of documentation of

• owner's assumptions and requirements;
• design intent, Basis of Design, and expected performance;
• verification and functional performance testing; and
• operation and maintenance criteria.

This guideline specifically details the process for

• conducting verification and functional performance testing and
• maintaining system performance to meet the current design intent after initial occupancy.

This guideline also includes a program for training of operation and maintenance personnel.
