Heating, Ventilation, and Air Conditioning (HVAC)
- Adjust your thermostat settings. We recommend 76°F - 78°F during cooling months and 66°F - 68°F during heating months.
- Check thermostats for accuracy.
- Reduce HVAC run time. Unless it's against your specific business/company regulations, turn off the system 30 minutes before closing time. The residual heat/cool will keep people comfortable.
- Contrary to popular belief, turning off HVAC and allowing a building to heat up or cool down does save energy dollars. Turn off HVAC when the building is unoccupied.
- Install a 7-day programmable thermostat for complete system control.
- Regularly clean or replace all filters and the coil (for outside units).
- Hire an expert to service your HVAC units on an annual basis.
- Install ceiling fans. They use very little energy and can significantly reduce AC demand.
Maximizing Windows, Doors, and More
- Windows and doors can settle and loosen, causing spaces that let in summer heat or winter cold. Caulk or weatherstrip gaps to eliminate drafts and air loss.
- Identify and fix doors and windows that don't close completely.
- Replace broken glass.
- Add blinds, shades, or curtains.
- Check the building's insulation. Not sure if it's insulated? Ask your landlord, if you rent, or request a free inspection from an insulation contractor.
- Turn off lights in unoccupied areas. Install switches with photosensors or occupancy sensors.
- Use timers to control lights' "on times;" regularly check automatic controls and replace them when they're not working properly.
- Use partial lighting before and after "public" hours.
- Reduce outside lighting. Consider using instant-on lighting that uses motion sensors. Use high intensity discharge (HID) lights, which are long-lived and efficient.
- Retrofit EXIT signs with compact fluorescent or LED bulbs. You'll add up to 100,000 hours of life!
- Remove incandescent lamps and replace them with more efficient, compact, low-wattage fluorescent lamps.
- Dust, grease, and other dirt that accumulates on lamps, lenses, globes, and reflecting surfaces can reduce light output as much as 30%! Professionals recommend cleaning light fixtures every other year.
- Have recessed lights? Install low-wattage reflector lamps which project the same amount of light as a higher wattage standard bulb.
- Need a tighter beam for displays? Switch to halogen lamps.
- Insulate the hot water storage tank or distribution pipes. If the tank feels hot or warm to your hand, it needs insulation.
- Clean out sediment that accumulates in the bottom of a tank water heater. Flush the water tank every six months by opening the drain valve near the bottom.
- Install a 7-day timer that controls water heater operation.
- Set your water heater to 105° if your company only needs hot water for hand washing or showers.
Machines and Equipment
- Check the NEMA ratings when you're buying a motor or equipment that needs a motor to operate.
- Buy high-efficiency equipment that is properly sized; consider a variable speed drive.
- Turn off machines when they're not needed. Install machines that have "energy saver" or "sleep" modes.
- Adjust controls to temperatures, speeds, or other settings that use less energy but still do the job properly.
- Regularly service energy-using equipment to maintain peak operational efficiency.
