ASHRAE Publishes First Zero Energy and Zero Carbon Building Evaluation Standard

ATLANTA (April 27, 2023) – ASHRAE has 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 measurement, and their balance.
