Implementing some of the below recommendations can save you 10% to 25% off your annual energy bill without negatively impacting comfort or productivity.

1. Your staff and students are the key to savings. Educate the students and staff on the why of energy saving - costs and environmental impacts. Encouraging them to actively participate in energy reduction is also important. Post reminders at exit doors and bulletin boards about energy conservation. Simple tips include:

a. Turn it down (lights, heating & cooling),

b. Turn it off (lights, computers, other equipment),

c. Keep it tight (close doors and windows, use window blinds)

2. Operations and Maintenance: Educate the O&M staff on the why of energy saving -costs and environmental impacts. Simple tips include:

a. Make sure that the Operations and Maintenance staff is properly trained for the equipment they operate.

b. Tune and clean HVAC: Perform seasonal cleanups on air conditioners, boilers and furnaces, and regularly clean cooling coils and drain pans. Get rooftop or outdoor condenser coils cleaned and maintain an appropriate filter changing schedule.

c. Check (or ask your HVAC contractor to check) your outside air dampers or economizers to verify proper ventilation. Make sure economizer controls function properly. Make sure automatic dampers close during unoccupied periods.

d. Restore automatic control: When troubleshooting a system, take time to figure out and repair the automatic controls. Today's quick fix is tomorrow's bad idea.

e. Reasonable set points: Try 69°F to 71°F in the heating season and 75°F to 77°F in the cooling season.

f. Schedule HVAC equipment and lighting: (weekdays, weekends, holidays, off-season). Make sure equipment runs only when it is needed and the buildings are occupied. When buildings are vacant (i.e. dormitories during the day with students in class), make sure all the lights in the building are off.

g. Seasonal (resets, schedules, and shutoffs): As the seasons change, adjust set points and schedules to match the system's response to the weather.

h. Lighting: Invest in an inexpensive light level meter to measure the foot-candles in spaces to determine whether or not they are over lit and lamps can be safely removed. Where four-lamp fixtures are in use, two lamps can usually be removed from every fixture or every other fixture. After lamps are removed, disconnect ballasts. Contact the Energy team at PBDewberry for suggested light levels for individual space types. Cleaning fixtures regularly increases light levels.

i. Utilize power management features for all computers and monitors to shut them off when idle for more than 15 minutes.

j. Have your vending machine suppliers turn off or remove light tubes from the advertising lighting in the machine. This will save about $50 per year per vending machine.

k. Save water with low flow sink aerators (0.5gpm) and low flow shower heads (1.5gpm - 2.0gpm). This will also reduce water heating energy consumption.

l. Set your water heater to 120°F. Verify by measuring at the tap. Never go below 115°F.

m. For water heaters installed in unconditioned spaces, add insulation blankets making sure that access covers, electric connection areas, and pressure relief valves are left uncovered.

n. Caulk and fill cracks around doors and windows to reduce costly air leaks.

o. When replacing broken glass, use high transmittance, low heat gain windows.

p. Make sure automatic door closers are functioning properly to avoid drafts.

3. Buy energy efficient, buy EnergyStar (www.energystar.gov).

a. Buy EnergyStar appliances and equipment.

b. Replace burned out lightbulbs with EnergyStar labeled compact fluorescent lightbulbs (CFLs).

c. Replace broken thermostats with EnergyStar labeled programmable products.

d. Replace broken exit signs with EnergyStar LED exit signs.
