Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. With tighter budgets and increased demand, you need innovative solutions to reduce energy costs and improve efficiency in your building. The buildings sector accounts for about 76%* of electricity use and 40% of all U.S. primary energy use making it essential to reduce energy consumption in buildings in order to meet national energy and environmental challenges and to reduce costs to building owners.
