Energy Saving Lowering the lid and covering braising pans and steam kettles saves up to 40%. Every 1 o F of cooling equals a 3% increase. Compact fluorescent lights (CFL) consume 75-80% less energy than incandescent lights. Strip curtains on walk-in refrigerators and freezers save four times more on energy. 5
Energy Saving Strategies Annual Servicing of Equipment Shut It Off Turn It Down Keep It Clean 6
Shut It Off Implement an equipment start-up & shut- down schedule ($1000/yr) Turn off exhaust fans ($600/yr) Install occupancy sensor or timer switches ($100/year) Install temperature control occupancy sensor walk-ins ($150/yr) 7
Turn It Down Reduce hot water usage ($800/yr) Install low-flow rinse spray nozzle ($450/yr) Preheat according to manufacturer specifications ($500/yr) Retrofit with energy-efficient lighting ($220/yr) 8
Keep It Clean Repair or replace broken control panels on ovens, steamers, and other appliances that feature control panels Clean condenser and evaporator coil and check pilot lights (US $500/year) Change air filters regularly (US $100/year) Replace worn door gasket (US $100/year) 9

Composition of School Food Service Waste By Weight 61-74% food waste By Volume 71-88% packaging 11
Waste by Volume Calculation 100 student/adult x 0.50 gallon per student/adult x 5 days of school per week = 250 gallons Waste hauler charges by volume number of gallons x = cubic yards 250 gallons x = 1.25 cubic yard dumpster 12
Food Waste Alternatives Food recovery programs Composting Vermicomposting (worm composting) Garbage disposal Dumpster/landfill 13
Water Usage School nutrition gal/student/day Restaurants gal/meal Nursing home15.7 gal/resident/day 14
Water Use by Individuals How many gallons of drinking (potable) water are used per day per person?
