Energy costs typically account for 15 percent of a warehouse’s operating budget. To better manage your building’s energy costs, ENERGY STAR has developed a checklist to help you identify simple, low-cost operations and maintenance practices that will increase energy efficiency and reduce electric bills in your warehouse. The practices cover several areas.


Restaurants are extremely energy intensive, using about 5 to 7 times more energy per square foot than other commercial buildings, such as office buildings and retail stores. High-volume quick-service restaurants (QSRs) may even use up to 10 times more energy per square foot than other commercial buildings. Most commercial kitchen appliances are also very energy intensive.


Most commercial kitchen appliances are energy intensive. Did you know restaurants use 5 to 7 times more energy per square foot than other commercial buildings and ENERGY STAR-certified equipment can save 10-70 percent more energy than standard models? Simple steps such as cutting idle time and repairing leaks in kitchens can heavily reduce energy use.


Leaks are a major source of wasted energy, usually squandering 20-30 percent of a compressor’s output. Compressed air leaks can also contribute to problems with system operations. Although leaks can occur in any part of the system, the most common problem areas are: couplings, hoses, tubes, fittings, pipe joints, quick disconnects, FRLs (filter, regulator, and lubricator), condensate traps, valves, flanges, packings, thread sealants, and point of use devices.


Known in the industry as the “Fourth Utility,” compressed air is one of the most expensive power sources in a plant. Even within the most efficient compressed air systems, only a small fraction of the energy required for the process – 10-15 percent – is ultimately delivered as compressed air. This quick guide from ENERGY STAR contains formulas, charts and suggested actions, that can help you determine your production costs for compressed air.
