How to Improve Your Building’s HVAC Efficiency
Energy remains one of the major overheads for commercial properties. According to the U.S. Energy Information Administration (EIA) in 2019, space heating accounted for about 38% of delivered energy in the building sector. With this in mind, regularly reviewing your building’s HVAC efficiency can help save money. Above all, investing in an energy-efficient system will also help fight climate change, create a sustainable future, and improve the building’s IAQ.
5 Ways You Can Enhance HVAC Efficiency
Optimizing your HVAC should start with the measurement and verification (M&V) of its current energy consumption. Measuring the energy input required against the current system’s output offers an accurate baseline of its performance.
Moreover, technology advances used throughout the system allow you to measure current consumption and calculate potential savings. Below are five considerations that can help maximize your energy savings.
1. Install Programmable Control Systems
Every component that makes up the system depends on airflow and temperature controllers. Both of which can fluctuate according to the indoor climate. However, you can now optimize your entire system using real-time data with programmable logic controllers (PLCs). This helps to manage changes automatically. Even more, some estimates suggest that installing an automatic HVAC optimization control system can save 10%- 25% on energy costs.
2. Review the Building’s Envelope and Insulation
HVAC systems perform better when operating in a closed system. Reducing air leaks and preventing thermal bridging between zones will help increase efficiencies exponentially.
If you operate an older building, consider upgrading the building envelope with an exterior insulation and finish system (EIFS). This helps with improving thermal efficiency. All in all, aging buildings are notorious for their poor energy and thermal performance.
3. Perform the Necessary Maintenance for Better HVAC Efficiency
Just like any other integrated system, HVAC systems require regular maintenance to remain efficient. So, arrange for an HVAC expert to inspect and maintain the entire system. And, do this as soon as possible. Especially if the system hasn’t received preventative maintenance in the last few years. Everything from the variable speed drives (VSDs) to the main air-handling units require regular maintenance from qualified technicians.
4. Ensure the HVAC System is Sized Correctly
Sizing the HVAC system’s air-conditioning units is vital to its overall performance. If the AC units are too small, they will run all day and drive up energy costs. Conversely, if the units are too big, they will run in quick bursts that could lead to reliability issues.
Most importantly, make sure to verify that the sizing of your AC plant is correct for your building’s requirements. To do so, consider requesting a professional assessment from a commercial HVAC company.
5. Consider Upgrading the System with New Technologies
You may want to consider commercial HVAC technologies to help offset your system’s operating costs. For example, radiant heating enables you to heat the building’s floors and walls. Thus, reducing the energy demand for your air distribution system.
