HVAC, Envelope and Whole Building Commissioning

Commissioning is a third-party quality assurance process that starts at design and continues through warranty to ensure that building systems are installed and operate as intended. Essentially, these services afford a thorough “debugging” of a facility’s systems. Commissioning validates the owner’s project requirements and ensures that the basis of design has been met and the building will operate properly. Commissioning provides added value to the owner/user of the facility, including:

  • Indoor air quality, temperature and humidity are “as designed” when the owner moves in
  • Systems are operating at the designed efficiency in all operational modes
  • Potentially disruptive post-occupancy troubleshooting and correctional work is minimized

Commissioning involves a systematic validation process of ensuring that new building systems perform interactively according to the documented design intent and the owner’s operational needs, and that specified system documentation and training are provided to the facility staff. Application of this process enables our clients to analyze their capital budgeted costs in concert with their operations budget to allow for the optimal ‘life cycle’ cost of the building systems.

HVAC Commissioning is defined by ASHRAE Guideline 1.1-2007, and can include the following building systems:

  • Primary heating, ventilating, air-conditioning and refrigeration (HVAC&R) equipment and systems (including components such as boilers, water-cooled chillers, steam generators, cooling towers, roof-mounted air-handling units, energy recovery units and pumps)
  • HVAC&R piping systems (heating hot water, chilled water, refrigerant, steam, etc.) and ductwork
  • Terminal equipment (such as cabinet unit heaters, fin tube radiation, exhaust fans, fume hoods, unit ventilators, etc.)
  • Building automation system (BAS) or automatic temperature control (ATC) systems

Building Envelope Commissioning is performed on new construction or large additions and addresses the exterior shell of the building. Building envelope commissioning ensures the integrity of architectural systems (such as window systems, wall systems and roof systems). Building envelope commissioning is typically performed to complement HVAC system commissioning, fundamental commissioning or enhanced commissioning.

Whole Building Commissioning is a term used in the industry to describe the application of HVAC&R commissioning and building envelope commissioning along with commissioning of any or all of the following building systems, including:

  • Electrical systems
  • Emergency power systems
  • Fire protection/detection systems
  • Data/technology/security systems

The commissioning process must begin early in the design phase of a project for owners seeking LEED certification of their facility. For non-LEED certified buildings, the commissioning process can be limited to the construction phase only.
