The Zero Tool – an Architecture 2030 project – was developed for building sector professionals to establish energy reduction baselines and targets, compare a building’s energy performance with similar buildings and to codes, and understand how a building achieved its current energy performance.
Architecture 2030, in offering the Zero Tool, accepts no responsibility or liability for the accuracy of the baseline and target data estimated by the Zero Tool, or for the design of buildings utilizing Zero Tool baselines and targets. The underlying assumptions and methodologies of the Zero Tool are based on those developed by EPA’s ENERGY STAR program, and are intended to serve as guidelines when setting performance targets and understanding (relative) building performance.
