Building Performance

Definition: Building performance is the cumulative energy performance and physical and operational characteristics of commercial and residential buildings that include cost effectiveness, safety and security, sustainability, accessibility, functionality, and productivity. Building performance is determined using basic energy consumption benchmarking, engineering audits and analysis, as well as sophisticated computer modeling and simulation. Typically, a comprehensive, whole-building approach is used to identify and fix comfort and energy efficiency problems in a building. Building science is usually applied to building performance to improve energy efficiency, durability, health & safety, indoor air quality, thermal comfort, and indoor moisture sources and solutions - and the systems that are designed to provide these features.
