HVAC Commissioning: Definition, qualified personnel and tips!

Definition of HVAC commissioning

Commissioning is defined as the process of assuring that all systems and components of a building are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client. Commissioning ensures optimised performance and efficiency of the HVAC system.

Commissioning consists of: commissioning, testing, balancing, troubleshooting, functional check of a system. All this should be documented and documentation handed-over to the client/owner.

Qualified personnel for commissioning

Only qualified personnel should carry out installation, configuration and commissioning. Majority of manufacturers of ventilation components require that the installation work, entering of settings and commissioning should be carried out by qualified personnel only.

Many of the manufacturers offer their own service, commissioning and maintenance personnel. When all is serviced by a professional serviceman, usually a better warranty is provided.

The pertinent national standards and regulations dealing with installation, configuration and commissioning must be followed if the equipment is to operate correctly. Check the EN (reference) CEN 13141 “Ventilation for Buildings – Performance Testing of Components / Products for Residential Ventilation and CEN 14134:2004 “Ventilation for Buildings – Performance Testing and Installation Checks of Residential Ventilation Systems”.

Important tips!

  • Do not commission the ventilation unit until all carpentry work that produces large quantities of sanding dust or other impurities has been completed.
  • The duct connection spigots of the ventilation unit must be covered by lids while the unit is being transported, kept in storage and mounted at its final location.
  • Make sure that the ventilation unit, filters and ducts are clean and that there are no loose objects in them before you commission the ventilation system.
