Consider this hard fact: We spend more on energy costs for schools in the United States than we do on textbooks and computers combined. Operating costs for energy and water in a green school can be reduced by 20% to 40% each year, allowing more money to be used for teacher salaries, textbooks, and computers. Here's how green schools save money:
Savings on Water Bills
Water is conserved from the use of low-flow aerators on bathroom and kitchen sinks and low-flush functions on toilets and urinals. Regular plumbing repairs and the use of low-water plants in landscaping also contribute to savings.
Savings on Energy Bills
Plans to turn off lights and equipment and to use sleep mode for machines not in use help contribute to lower bills. Energy Star-rated equipment and appliances are used to reduce electricity consumption. The average U.S. school can lower its energy bills by 30% simply through promoting energy-saving behavior.
Savings on Heating and Cooling Bills
Programmable thermostats help keep heating and cooling costs down. Insulation and sealed windows also contribute to savings.
Savings on Lighting Costs
Florescent lighting bulbs do not need to be replaced as frequently as incandescent bulbs. Sensors on lights cut down on use as well. Natural daylighting also reduces the need for artificial light.
Savings on Waste Removal
Reusing and recycling and composting food scraps helps cut down on waste removal costs.
