Your HVAC system uses a substantial amount of energy

HVAC stands for heating, ventilation and air conditioning systems, which are responsible for the majority of energy use in most commercial buildings. Taking proper care of your system keeps it running more efficiently, so you can save money on energy use and avoid the emissions associated with replacing it with a new one.

57% of the energy used in commercial and institutional buildings is used for heating.1
 $2.2 billion in energy costs has already been saved since 2000 in the commercial and institutional sector through energy efficicency improvements.1

On average, SMEs that optimized their HVAC system took 22 months to recoup their investment.

Roadmap to HVAC optimization

HVAC systems work continuously almost all year long, which exposes them to potential malfunction or breakdown. Scheduling regular maintenance at least once a year is a good way to prevent issues, or at least reduce their frequency and complexity. Also, keep an eye out for leaks or visual signs of wear and listen for any unusual noises coming from your system.

Modern HVAC systems are highly complex and calling on an HVAC specialist is often the best way to manage a system effectively. Still, there are some general things you can do without an expert:

  • Change air filters regularly
  • Improve your building’s insulation
  • Keep indoor vents clear and make sure nothing is blocking the vents (like pieces of furniture)
  • Clean around the condenser unit (keep the surroundings free of debris, bushes, etc.)

Keep an eye on your utility bills or install sensors or smart thermostats to monitor the energy use of various system components. Spikes or other significant changes in energy use should be investigated and addressed as soon as possible. For example, if your monitoring shows a surge in energy use overnight, check your settings to make sure you’re not running the system unnecessarily when no one’s in the building. On top of that, behaviour changes such as lowering the heat by 1 degree Celsius in winter can reduce your heating costs.

If you find yourself calling in repair technicians too often, or you just can’t get the performance you’re looking for from your system, it might be time to consider a replacement.

Choosing an energy efficient option can result in a higher cost upfront but can be offset many times over by the lower cost of operating it over the long term.

Look around for the most energy efficient solution that suits your needs. For example, a heat pump is an efficient electrical device that moves heat around your home and can be used in both summer and winter.

When buying new equipment, look for an ENERGY STAR® certified product to make sure you’ll reduce your energy bills as much as possible.

Besides choosing an energy efficient system, ask your HVAC technician about the type of gas used to run the compressor. Some gases contribute more to climate change than others and will therefore increase your GHG emissions.
