ASHRAE publishes zero energy and zero carbon building evaluation standard
May 2, 2023 | By HPAC Magazine
Standard 228 provides a consistent method for determining whether new and existing sites have reached zero energy.
ASHRAE has released a new standard to measure zero net carbon and energy goals in buildings.
The new 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.
“Achieving a zero energy building has been viewed by many as a difficult goal to meet, with unforeseeable roadblocks and differing guidance,” said Keith Emerson, P.E., chair of the Standards Project Committee 228.
“Standard 228 provides a consistent method for determining whether new and existing sites have reached zero energy. We hope this standard will become a helpful resource for building professionals in strategic decarbonization planning.”
