Commercial HVAC systems have become increasingly complicated and difficult to implement. Verification has similarly become complex as a result. From LEED requirements to the various local, national, and international building construction codes, all of which can sometimes conflict, the level of complexity increases almost daily. One important aspect of a modern temperature control strategy is commercial HVAC commissioning.
What Is Commercial HVAC Commissioning?
Commissioning, in plain English, is the process of checking and verifying that all systems are properly installed and functioning according to their official specifications. This process should be performed when the equipment is installed. It may be performed again as needed should the system experience any performance issues. It also may be revisited over time if the building’s energy, air quality, or thermal comfort performance is not meeting expectations.
Why Is Commercial HVAC Commissioning Important?
There are several reasons commercial HVAC commissioning is essential. First of all, building owners, contractors, and engineers are legally required to maintain proper documentation on their HVAC systems and their performance.
HVAC commissioning also allows the early identification and resolution of issues, which can reduce callbacks and repairs over time. Periodic HVAC commissioning also leads to a general improvement in system performance and efficiency.
What Is Done When a Commercial HVAC System Is Commissioned?
Here is an example of items that usually appear on an HVAC commissioning checklist.
- Test for Air Leakage. As your grandmother might say, don’t air condition the outdoors.
- Test for Duct Leakage. This maintains energy efficiency.
- Pressure Mapping. Pressure imbalances can cause more air leakage.
- Total External Static Pressure. Poorly installed ducts can create high static pressure that resists the blower.
- Outside Air Flow Measurement. This involved making sure the amount of air the system brings in doesn’t overwhelm your heating and cooling system.
- Temperature Drop. A properly working air conditioner should have a temperature drop of 20° F. This is an easy way to find problems.
- Exhaust Fan Air Flow Measurement. Most restroom fans are poorly installed and only get about half their rated airflow.
