HVAC Energy Efficiency
Since your HVAC system can account for up to 30% of your energy usage, it pays to improve its efficiency.
Before you consider buying a new HVAC system or making elaborate renovations, consider the following five simple ways to cut your system’s operating costs.
- Turn it off. Experiment to determine how long it takes for your space to heat up or cool down. Time your thermostat to turn on shortly before occupants arrive and to shut off one half-hour before they leave, so you keep your space temperate only when it’s full of employees. You’ll save money by only using your HVAC system when you need it.
- Manage the building envelope. Let in only the air you want, and don’t let the tempered air escape.
- Draw in outside air .Outside air is a natural and efficient coolant, especially at night. Let in cool night air to pre-cool your building for the next day. To flush warm air out, vent the cool side of the building or operate attic vents and fans on that side.
- Adjust air duct registers. Adjust vents to manage the flow of tempered air and increase your employees’ overall comfort level.
- Use exhaust fans sparingly. Save energy and money by using sensors or timers to ensure your exhaust fans run only when needed.
- Keep your HVAC system clean. Careful maintenance improves efficiency, reduces waste, and lowers costs.
If your HVAC system is particularly old or inefficient, serious renovations or an entirely new system will enable you to take full advantage of the newest heating and cooling technologies. This will improve the performance of your HVAC system — and will lower your bottom line – considerably.
