Investment Tips
- Retrofit lighting. Convert T12 lights and magnetic ballast to T8 lights and electronic ballast. Install occupancy sensors, which can reduce lighting costs by up to 40%. Convert hallway and non-public security lighting to energy saving 25-watt T12 bulbs. Convert TV surveillance cameras to newer equipment, which may not require floodlighting.
- Weatherize buildings. Install awnings, solar shade screens or sun-control film for windows, and apply a heat-blocking coating to your roof.
- Install an Energy Management System. An EMS will control heating, ventilation, and air conditioning equipment and lighting systems automatically to maximize efficiency and savings.
- Buy ENERGY STAR products
ENERGY STAR certified equipment and products use less energy than other products, save money on utility bills, and help protect the environment. Establish a policy of only buying ENERGY STAR certified equipment such as computers, monitors, and printers.
Special Tips for Schools and Large Facilities
Schools
- Sensors, timers, and control mechanisms can increase efficiency by responding to occupancy patterns that may vary dramatically during the day. These can be used for lighting, appliances, and temperature controls for air and water.
- Choose an energy monitor for your classroom every week who will make sure that energy is being used properly.
- Start an "Energy Patrol" at school and at home.
Hospitals
- Combined Heat and Power (CHP) systems are a viable option for reliable energy and hot water. An Energy Management System (EMS) can accommodate changes in ventilation needs and increase efficiency. The HVAC system should be able to respond to occupancy changes and not waste energy when rooms are empty.
Museums, Libraries, and Other Public Facilities
- An Energy Management System is a viable option in buildings with regular hours. Timers and sensors can respond to occupancy as needed. HVAC systems, too, can respond to occupancy with carbon dioxide sensors to increase efficiency.
