9 Ways 9 WAYS TO SLASH YOUR BUILDING'S ENERGY CONSUMPTION We’re getting better at saving energy. But, when it comes to efficiency, the job is never done. Here are nine ways you can slash those costs even further. 9. Roofs The color of your roof can help cut energy costs and even avoid the need to air condition. TIP Install a white or cool-colored roof. 8. Insulation The building envelope is responsible for 25% of building energy, but impacts up to 57% of commercial use. TIP Boost savings with efficient building envelope surfaces and coatings. 7. HVAC Space heating consumed 25% of a building’s overall energy use in 2012. Ventilation consumed 10% and cooling, 9%. TIP Dial down energy use with regular HVAC maintenance. 6. Daylighting Expanding the use of natural light (“daylighting”) can save up to 60% in lighting energy in many commercial buildings. TIP Add a window or skylight for maximum southern exposure. 5. Water 46k large buildings used about 980 MM gallons of water per day in 2012, ~2.3% of the total U.S. public water supply. TIP Update restrooms with water-saving faucets and toilets. 4. Lights Lighting energy use declined by 46% from 2003 to 2012 in commercial buildings, consuming about 10% of a building’s overall energy use. TIP Use CFL or LED bulbs wherever possible. 3. Shades or Awnings Solar heat gain through windows affects the cooling load of many commercial buildings. Shades or awnings make a big difference. TIP Opt for windows with low-E coatings and tints. 2. Building Automation Ineffective controls can result in significant energy waste, but only 10% of U.S. buildings have a building automation system. TIP Install intelligent controls to automate key building functions. 1. Doors & Windows From direct conduction to air leakage, your doors and windows can gain and lose heat in so many ways. The fight for efficiency starts here. TIP Choose windows and doors with low air-leakage ratings.
