HVAC SYSTEMS COMMISSIONING MANUAL - First Edition; Third Printing: April 2004
Year: 1994
Abstract: The HVAC Systems Commissioning Manual is intended to cover the full range of HVAC equipment and systems typically found in commercial and institutional buildings.
The level of commissioning varies to suit the specific requirements of each project as determined by the owner.
The manual describes in detail the commissioning process for three different levels of commissioning. In addition, as an aid to users, it provides examples of pre−start checklists and functional performance test checklists for many types of equipment and systems. These include:
• Hot water and steam boilers; with atmospheric or power burners; gas, oil, or combination gas/oil fired.
• Chillers; with reciprocating, scroll, screw, or centrifugal compressors; air cooled or water− cooled; with or without condensers; and including heat recovery models.
• Cooling towers, closed circuit heat rejectors, and both air cooled and evaporative condensers.
• Hot water, chilled water, and condensing water pumps associated with the preceding.
• Constant volume, single zone air systems (including all components such as fans, coils, furnaces, condensing units, dampers, and controls, as applicable).
• Constant volume, reheat air systems (including all central equipment, zone reheat components, and controls).
• Variable air volume (VAV) systems (including all central equipment, VAV terminals, and controls).
• VAV reheat systems (including all central equipment, VAV reheat terminals, and controls).
• VAV systems with fan powered terminals (including all central equipment, fan powered VAV terminals, and controls).
• Water loop heat pump systems (individual heat pumps and loop pumping, heat rejection, and supplementary heating).
• Fan coil units (including their controls and the systems used to provide them with outside air, heating, and cooling, as applicable).
• Outside air makeup and exhaust systems.
• Pressurization systems, for fire emergency use.
• Smoke control systems.
• Controls integral with any of the preceding equipment and systems.
• Valves, sensors, actuators, and controls external to the equipment, but required for control of fluid flow, temperature, or other parameters.
• In addition to the preceding specific equipment and systems, the manual also covers the commissioning of automatic actuation interfaces between HVAC systems and other building systems. The most common of these are fire alarm systems and sprinkler systems.
PURPOSE
Over the past several years, there has been increasing recognition in the building construction industry of the need for effective building systems commissioning. For a number of reasons, industry commissioning efforts have focussed on heating, ventilating and air conditioning (HVAC) systems. First, HVAC systems are among the most complex and interconnected of building service systems. Second, considerable energy is consumed in HVAC systems. Inefficient operation increases operating cost. Third, occupant comfort demands and concerns about substandard indoor air quality are both increasing. HVAC systems must be designed properly, then installed, operated, maintained, and serviced correctly, if both comfort and indoor air quality are to be attained.
The primary purpose of this manual is to provide guidance to contractors on how an effective HVAC systems commissioning process should be planned and carried out. A second purpose is to provide a clear explanation of the reasons for commissioning to make it understandable for a broad cross section of the industry. Contractors who understand commissioning are in a position to sell its use to owners, designers, and others.
Another purpose of the manual is to provide guidance on recommissioning HVAC systems in existing buildings. Any existing building with poor temperature control, dissatisfied occupants, excessive energy or maintenance costs, or other evidence of improper design or operation is a candidate for recommissioning. Because there are many existing buildings with these characteristics, and owners often contact contractors directly for remedial work on them, provision of recommissioning services is a potentially important field for knowledgeable contractors.
This manual covers commissioning during the construction phase of a project in considerable detail. It puts particular emphasis on the commissioning agent, the commissioning authority, the commissioning plan, communication and coordination during construction, and commissioning documentation. This is to give the clearest possible guidance to contractors and others whose involvement is primarily during the construction phase of a project.
This manual does not provide material specific to any particular building. The material within is intended to cover the entire commissioning process, providing not only organizational and procedural steps, but also the rationale behind them. This assists users of the manual to adapt the information to the successful commissioning of building projects.
