HVAC Savings Easy Savings
Turn heating and air-conditioning systems down or off when not in use (weekends/nights). This will contribute to energy savings of 10-30%. Use “auto” setting instead of “on” setting. “On” means the system runs 24/7; “auto” means a fan will cycle only when it is heating or cooling a space Change your temperature settings. Lower thermostat to 68 degrees in winter; raise thermostat to 78 or higher in the summer. Gradually get to these levels so employees have time to adjust. Employees may not even notice if you change your thermostat just one degree each week. Plus each degree of a higher temperature setting can save about 3% on cooling costs. Replace air filters at least quarterly, and once a month in peak heating and cooling months. Air will be cleaner and systems will perform better. Plug or fill any cracks or leaks (around windows, doors, outlets/switches) with weather stripping and caulking Install ceiling fans. In summer, they’ll allow AC to work less at higher, more efficient temperatures and they’ll circulate cool air; in winter, the fans will help pull warm air down and the heating system will be able to operate well at lower temperatures Open windows in the spring and fall to bring cool air in and let warm air out
Hiring an Expert
Inspect your thermostat. It may be overworking and costing you extra money. Have a technician recalibrate or replace it if this is the case Get a programmable thermostat: automatically controlled HVAC systems are more efficient and more dependable. Available for $50-$200, you can establish set points and cutoff times for a week and if you need to change it for an employee working overtime or when the facility is closed, you can use the manual override features. If your facility uses large, central systems (boilers/chillers), consider getting an energy management system (EMS). They reduce energy costs by nearly 20% with a payback period of less than 4 years.
Maintenance for Your HVAC System Purchase a semi-annual service maintenance agreement (SMA) with a licensed HVAC contractor to ensure your system lasts and performs well. It’s as important as an oil change for your car! The SMA should include:
Checking the system’s connections Adjusting temperature and humidity set points Inspecting and oiling fan motors Checking for proper airflow at the unit and each zone Checking for proper control settings and safety shut-down functions Inspecting and repairing duct leaks and insulation gaps
