Core Performance

Core Performance®, the cornerstone of the Advanced Buildings® suite of technical tools and resources, is a direct, simplified approach to achieve predictable energy savings in small- to medium-sized buildings without the need for modeling.

The nationally recognized, easy-to-use, Core Performance Guide brings together over 30 criteria defining high performance in building envelope, lighting, HVAC, power systems and controls. When applied together in an integrated design process, these measures result in buildings that are 30% more energy efficient than model building standards.
