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.

The committee is seeking comments on proposed revisions to the standard’s title, purpose and scope as well as the remaining content being proposed in the document. Specific questions are included in the document for stakeholder input.

Exam development and form creation will begin in the summer 2023 and updated exams will launch in the first quarter of 2024.

The two highest-ranking project teams are invited to present their projects during the Student Program at the 2024 ASHRAE Winter Conference, taking place Jan. 20-24, 2024 in Chicago.

The 2024 Winter Conference will take place Jan. 20 – 24, and the AHR Expo, Jan. 22 – 24, in Chicago.

The ASHRAE Task Force For Building Decarbonization (TFBD) webpage includes technical resources, information, videos and publications to expedite the adoption of climate change mitigation policies.

Dubbed the largest HVACR event of the year, the 2023 AHR Expo returns to Atlanta Feb. 6-8, while the co-located 2023 ASHRAE Winter Conference will take place Feb. 4-8 at the Omni Hotel at CNN Center and Building A of the Georgia World Congress Center.

ASHRAE will set up a balanced team of internationally recognized experts to work on an accelerated timeline to develop the standard.

The conference includes both in-person and virtual options for attendees. 

ASHRAE, along with 24 of the world’s leading building industry organizations issued a statement to government representatives attending the United Nations Climate Change Conference of the Parties (COP 27) pledging to assume a leadership role in decarbonization efforts in the built environment.
