ASHRAE publishes first zero energy and zero carbon building evaluation standard
The standard draws from ASHRAE Standard 105, among others
ATLANTA — ASHRAE released a new standard to measure zero net carbon and energy goals in buildings.
ANSI/ASHRAE Standard 228-2023, Standard Method of Evaluating Zero Net Energy and Zero Net Carbon Building Performance, sets requirements for evaluating whether a building or group of buildings meets a definition of “zero net energy” or a definition of “zero net carbon” during building operation. The standard draws from ASHRAE Standard 105, among others, to address energy and carbon flows across a site boundary, their measurements, and their balance.
