CoolSys Energy Design commissioning services ensure that a building’s engineered systems are installed, programmed and operating properly and as specified.

To ensure a new building’s systems are correctly installed a commissioning (Cx) program led by an experienced and certified CoolSys Energy Design Commissioning Agent (CxA) may be incorporated into all building phases, including design, construction and start-up. Likewise, a retro-commissioning process is used to identify and improve less-than-optimal energy performance related to an existing building’s equipment and control systems.

Whether the need is a new building Cx, retro-commissioning, LEED commissioning or a specific discipline such as HVAC or refrigeration system Cx, CoolSys Energy Design certified Commissioning Agents have the engineering know-how and expertise to deliver.


  • Development of commissioning strategy to suit specific building types

  • Proper start-up and functional testing of:
    • HVAC
    • Refrigeration
    • Exhaust and make-up air fans
    • Cooking hoods
    • Air distribution
    • Chilled and condenser fluid pumping networks

Our Energy Performance Monitoring service provides you with a laser focus on equipment and building energy performance, assuring that all of your systems, including the controls, are operating in their optimum mode. Even when everything “seems fine,” the systems may be operating inefficiently attempting to achieve desired set points. We can help identify these, by the application of granular level power metering, to uncover inefficiencies and save thousands of operational dollars.
