- Replace light bulbs with ENERGY STAR qualified fluorescent lamps (CFLs). CFLs cost about 75 percent less to operate and last about 10 times longer.
- Switch to T8 fluorescent lamp tubes with solid-state electronic ballasts that are more efficient than older T12 tubes with magnetic ballasts.
- Turn off lights and other electronics when not in use.
- Install switch plate occupancy sensors to automatically turn off lighting if there’s not someone in the room.
- Install ENERGY STAR qualified exit signs.
Heating & Air Conditioning
- Change HVAC filters monthly during peak cooling or heating seasons. New filters usually only cost a few dollars. Dirty filters are more costly to use and overexert the equipment.
- Tune-up your HVAC systems with an annual maintenance contract. A contract ensures that your HVAC contractor will provide tune-ups before each cooling and heating season.
- Install an ENERGY STAR qualified programmable thermostat to automate your HVAC system. This solid-state, electronic device optimizes HVAC operation "24/7" based on your schedule and can be "overridden" as needed for unscheduled events.
- Plug leaks with weather stripping and caulking, which lets you manage your ventilation.
Food Service Equipment
- Purchase ENERGY STAR qualified commercial food service equipment. They can save over 45 percent of the energy used by conventional models, which equals about $140 annually for refrigerators and $100 for freezers; deep fryers can save up to $180 per year; hot food holding cabinets can save up to $280 per year; and steam cookers can save up to $820 per year.
- Service walk-in refrigeration systems once a year. That includes cleaning, refrigerant top off, lubrication of moving parts and adjustment of belts.
- Buy ENERGY STAR qualified products, which are the most efficient computers, printers, copiers, refrigerators, televisions, windows, thermostats, ceiling fans and other appliances and equipment.
- Turn off machines when they are not in use. Automatic switching to sleep mode or turning computer off is a great energy-saving strategy.
- To maximize savings with a laptop, put the AC adapter on a power strip that can be turned off (or will turn off automatically).
- Use a laptop; they use less energy than desktop computers.
- Unplug battery chargers once the batteries are fully charged.
