Energy Efficiency Ratings— Benchmarks that Drive Excellence in Building Design and Operations
Various rating systems for green buildings—LEED, Energy Star, NABERS, and Green Star—are expanding in scope, depth, and precision, and have been established in more than 100 countries. The rating systems bring meaning and professional integrity to energy-efficient design and operation to buildings, as well as products and appliances. The rating systems afford easy comparison among cohorts ("like" buildings), and serves as a competitive stimulus to drive progress in building operation and design.
