The process of ensuring that the HVAC (Heating, Ventilation, and Air conditioning) systems of buildings operate correctly and serve their intended purpose, HVAC commissioning is considered to be a vital part of the overall construction process—from designing, building, managing, and maintaining an HVAC system. Typically, HVAC commissioning is applied to the two most common examples which are commercial and residential. In the general context of commercial buildings, HVAC systems are usually one of the biggest energy consumers. If the installation doesn’t operate correctly, it can affect the overall performance of the system and further increase energy consumption.
