Top 10 Energy Efficiency Tips
- Turn off computers and other office equipment when they're not being used, especially overnight and weekends. Cost: Nothing! Savings potential: As much as $44 per year, per computer, depending on what you pay per kilowatt-hour.
- Install an occupancy sensor in hallways, bathrooms and other areas where lights can be left off most of the time. Cost: Between $25 and $80. Savings potential: About $40 per year depending on where the sensor is installed.
- Lower the thermostat on your water heater. Cost: Nothing! Savings potential: About $24 per year, if the setting is reduced by 10 degrees F, and operates at the lowest allowable temperature for normal use.
- Turn off your water heater overnight and on weekends. Cost: Nothing, or $30 if you buy an automatic timer to do it for you. Savings potential: As much as $54 per year depending on how much hot water you use.
- Set back your thermostats at night and on weekends. Cost: Nothing! Savings potential: About $1,800 per year for a 33,000-sq. ft. office building with a thermostat set at 75 degrees F, 24 hours per day during the heating months.
- Close drapes or blinds in warmer months to keep the sunshine from overheating your house. Just do the opposite in the colder months to give your thermostat a break. Cost: Nothing! Savings potential: About $5 per window depending on location and time of year.
- Clean all air filters monthly. Cost: Nothing to clean, and about $2 if you need to replace one. Savings potential: As much as $60 per filter, depending on the size of your HVAC system.
- Check for drafts coming from doors and windows, then caulk and weather-strip them as necessary. Cost: $5 or less. Savings potential: About $2 per fixed draft.
- Adjust your thermostats for colder weather. Simply set them at the lowest temperature allowable that keeps employees and customers comfortable. A setting of 70-75 degrees Fahrenheit (F) is the standard industry recommendation. Cost: Nothing! Savings potential: About $1,000 per year for a small office building open Mon.-Fri., 7am to 7pm.
- Install LED exit signs. They're 100% longer lasting than conventional exit signs and the most energy efficient of their kind! Cost: About $70 to retrofit. Savings potential: About $24 per year, per sign, not to mention the maintenance savings.
