Commercial Energy Saving Tips BUILDING AND DESIGN TIPS General cooling measures. Think carefully about using "green" design features. Use evaporative cooling wherever possible. Attempt to use natural ventilation and light surfaces. Encourage day lighting of interior spaces in the design. Surround all buildings and cover parking lots with trees to reduce local environmental temperatures. Specify light colored aggregates for local access road and sidewalk pavements. Landscaping and use of shade. Combine architectural features and shading so that a minimum of the building envelope is exposed to the sun. Design landscaping around the building and over parking areas so that no parking area is exposed to the sun. This will not only reduce the heat build-up in parked vehicles, but will reduce the temperature of air blowing against the building by 6 to 8 degrees. Combined heat and power systems. Often there is a balance between the heat requirements of an institution and its electrical needs. This energy match means that the waste heat from a small electrical generator can be used to generate electricity. Solar power on rooftops. Consider installing solar electric collectors on the roof. Ensure that the building design includes adequate support for the dead weight load and the wind stress, and all conduits for pipes or wires. Water, gas and ventilation. Design a gray water collection system for irrigating landscaping. If natural gas is unavailable, consider ground source heat pumps. Design public space ventilation to respond to occupancy needs with such features as carbon dioxide detectors. Avoid air curtains that allow air leakage from conditioned spaces. Pressurize and test all ducts for leakage before dropped ceilings are installed. Engineering requirements. Be sure that Performance Assurance or building commissioning is included in the engineering services provided by the engineer. General Tips Commercial Tips EnergySaver™ Conservation Rate
