In summer, energy costs for cooling often rise along with the thermometer. Peak demand charges also become a significant issue in many homes and farm operations. The following energy-saving guidelines will help keep your energy budget from slipping into the red as summer heats up.
Cooling systems
Although it's essential for comfort, air conditioning is a substantial summertime operating cost for most facilities. Use these cost-saving tips to help cool off your energy bills:
Verify all maintenance has been performed on your air conditioning equipment and change filters regularly according to manufacturer's guidelines.
Raise thermostat settings by a few degrees during times of day when you are away from the home.
Check and update HVAC control settings on your home or building automation system to account for the changing season and your schedule.
Use window treatments to prevent unwanted solar heat gain from entering your home.
Install window film, solar screens, or awnings on south- and west-facing windows to provide cooling shade on hot summer afternoons.
If your air conditioning system is 10 years old or older, or in regular need of repair, consider installing a new, energy-efficient system. Work with a qualified HVAC professional to properly size the system for your needs.
Reducing demand
Demand charges can make up a significant portion of your energy bills during the hot summer months. The following strategies will help you level off your peak demand:
Operate large appliances and equipment during off-peak hours in the evening or early morning.
Close window coverings and blinds to keep summer sun and heat at bay.
Consider setting your thermostat at 78 degrees from noon to approximately 8 p.m.
