The I/UCRC for Building Performance and Diagnostics at Carnegie Mellon University (EEC-9713936) has developed award-winning “Guidelines for High-Performance Buildings” that permit significantly reduced energy and environmental impact in building construction and operation (by a factor of five compared to best current-day practices) while at the same time dramatically improving indoor environmental quality (air quality, thermal quality, visual quality, acoustic quality and spatial/ergonomic quality), also by a factor of five or more. These guidelines have been applied, with the active participation of the Center as systems integrator, in many government and commercial building projects around the world, including not only the United States but also buildings in Korea, Germany, France, and China. The work has proved that both saving energy and improving environmental quality can be accomplished.
