The proposed ASHRAE/ICC Standard 240P – “Evaluating Greenhouse Gas (GHG) and Carbon Emissions in Building Design, Construction and Operation” is open for comment from April 21 to May 21.
The committee is seeking comments on proposed revisions to the standard’s title, purpose and scope, and the remaining content being proposed in the document.
Standard 240P was created to provide a methodology to quantify and document GHG emissions associated with buildings, building systems, and equipment over their lifecycle.
The standard covers the following:
- Existing buildings, new buildings, groups of buildings, or portions of buildings.
- Determination, including calculation methodology and expression of the building(s)
zero net GHG and zero net carbon dioxide emissions status for building operation.
- GHG emissions associated with flows across the site boundary and off-site credited flows.
- Embodied GHG emissions of building materials and systems.
“The accelerated pace in which a draft of Standard 240P was developed speaks to the extraordinary technical knowledge and leadership of the committee and its chairs. ASHRAE remains committed to advancing effective building decarbonization strategies and was pleased to partner with the code council to develop this much-needed resource,” said Farooq Mehboob, ASHRAE president.
Standard 240P also offers procedures and minimum requirements for quantifying embodied and operational GHG emissions, including reporting and documenting.
ASHRAE and the ICC approved a joint committee to develop the standard on Dec. 8, 2022. The committee developed a draft for Standard 240P in four months, a task that typically takes six to 12 months.
