Building commissioning (Cx) is a method of risk reduction for new construction and major renovation projects to ensure that building systems meet their design intent, operate and interact optimally and provide the owner what he or she expects. This systematic process typically includes building HVAC, controls, lighting, hot water, security, fire, life and safety systems.

Total building commissioning often includes additional essential buildings systems such as the building's exterior wall, plumbing, acoustical and roofing systems. Commissioning these additional systems can reduce moisture penetration, infiltration and noise problems, and contribute to the building's energy and resource efficiency and occupant productivity.

Our commissioning agents and our firm are both Nationally Certified.

Commissioning (Retro)

The commissioning process can be applied to existing buildings that have never been commissioned to restore them to optimal performance. Retro-commissioning (RCx) is a systematic, documented process that identifies low-cost operational and maintenance improvements in existing buildings and brings the buildings up to the design intentions of its current usage.

RCx typically focuses on energy-using equipment such as mechanical equipment, lighting and related controls and usually optimizes existing system performance, rather than relying on major equipment replacement, typically resulting in improved indoor air quality, comfort, controls, energy and resource efficiency.
