How to reduce hotels energy bill

Many hotels and motels can benefit from quick low-cost or no-cost solutions for saving energy in various parts of their operations.
Peripheral and back rooms - Make sure that HVAC settings in lobbies, offices, and other such peripheral rooms are at minimum settings during hours of low use.
Laundry - Set laundry hot water temperatures to 120° Fahrenheit. This is a good temperature for all hot water uses outside of the kitchen, where codes are specific about water temperature.
Pools and hot tubs - Make sure that all pools and hot tubs are covered after hours to diminish heat loss. Covering a heated pool can save 50 to 70 percent of the pool’s energy use, 30 to 50 percent of its makeup water, and 35 to 60 percent of its chemicals.
Housekeeping procedures - Encourage housekeepers to turn off all lights and set temperatures to minimum levels after cleaning each room. Closing drapes when a room is unoccupied will reduce heat gain in the summer and heat loss in the winter.
Kitchen and food prep - In the kitchen, food preparation equipment should not be turned on for preheating more than 15 minutes before it is needed; simply reducing the operating time of kitchen appliances can cut cooking-related energy consumption by up to 60 percent.
Bathrooms and fitness rooms - Use automatic faucet shutoff, single-temperature fittings, and low-flow showerheads with pause control to reduce hot water waste in bathrooms and fitness rooms.
Front desk - Teach registration staff that they can help save energy costs by booking rooms in clusters, so that only occupied building areas or wings need to be heated or cooled to guest comfort levels. Rooms on top floors, at building corners, and facing west (in summer) or north (in winter) can be the most energy-intensive to heat or cool; therefore, consider renting them last.
Computers and office equipment - For hotel office spaces, a computer monitor can use two-thirds of the total energy of a desktop system, so it is important to power down monitors whenever they are not in use.
Guest service options - Some lodging facilities offer guests the option of forgoing daily linen changes or nightly turndown service. Some guests may not perceive a need for daily sheet and towel replacement or for lights, radios, or televisions to be turned on for them when they are not in the room.
