What is Commercial HVAC Commissioning and What Does it Involve?
Heating, ventilation and air conditioning systems (HVAC) are responsible for maintaining air quality and regulating temperature in commercial buildings. To do this effectively, they must be designed and installed to an exacting standard. They must also be thoroughly checked and tested post installation through a process known as HVAC commissioning.
This process involves a complex set of activities that must be carried out by qualified professionals.
The purpose of HVAC commissioning is to ensure the system in question functions as its operator intended, and that all components are installed according to both system design and manufacturer instructions. It’s also an obligation for all works approved under UK Building Regulations Part L: Conservation of Fuel and Power.
Types of HVAC Commissioning
Generally speaking, commercial HVAC commissioning takes one of three forms:
Initial Commissioning: this involves the testing of a brand new HVAC system installation. Testing is carried out to ensure the new system meets client requirements and design intent.
Retro-Commissioning: this is what we call the commissioning of an HVAC system installed more than 12 months prior but yet to undergo initial commissioning.
Re-Commissioning: this is the process of testing a previously commissioned HVAC system to check it’s still compliant and still meets owner and design specifications. Depending on the circumstances, repairs or upgrades may be required to bring the system in line with these criteria.
There’s also the process of HVAC decommissioning, which refers to the safe shut down and removal of an existing HVAC system, either to retire or relocate it.
