A building’s HVAC system is rarely thought about unless something goes wrong with it. If the system is working as intended, most building managers and owners don’t even give them a second thought. It’s only when something goes wrong or breaks that help is called in to repair any part of the system. While this seems like a logical route to take—don’t fix what isn’t broken—building owners and businesses are losing out on billions of dollars in excess energy costs due to the inefficiencies of their HVAC systems.
HVAC systems are a series of machines and other operational components. Like any other machine, they require maintenance to continue to operate at peak efficiency. Your HVAC system uses about 35% of the total energy in your building, so enhancing its efficiency can save you a lot of money over time.
There are many causes of HVAC inefficiency in commercial buildings. These include:
Many of these issues lead to an HVAC system becoming imbalanced, which can result in negative building pressure, among other issues. Negative building pressure can be recognized by these signs:
It's also possible to measure the building’s air pressure and changes in air pressure using an HVAC monitor.
Even well-maintained HVAC systems can be inefficient if they were not designed and/or installed properly. Some newly constructed buildings have subpar HVAC systems that result in inefficient use of energy, poor air quality, and building pressure issues. That’s why building commissioning services are so crucial to HVAC optimization. These services start in the design phase of the building, helping to map out HVAC systems and ensure all the necessary components are included and installed properly.
Commissioning services can also be done to existing buildings. Known as retro-commissioning, this process allows HVAC experts to improve HVAC performance and energy efficiency by analyzing building systems and correcting existing issues, whether large or small. This process can be repeated on a continual basis, ensuring the building’s HVAC system continues to efficiently use energy and cut down on HVAC utility costs.
