IAPMO and ASHRAE to co-publish water efficiency standard
March 23, 2021 By Anthony Capkun
March 23, 2021 – The International Association of Plumbing & Mechanical Officials (IAPMO) and ASHRAE will co-publish a document to address water efficiency in buildings.
“Water efficiency and energy conservation are major considerations in the design and operation of HVAC systems in high-performance buildings,” said Charles E. Gulledge III, PE, ASHRAE president. “Escalating costs and concerns regarding availability have brought much-needed attention to the issue of water use in the built environment.”
The document will combine ASHRAE 191P “Standard for the efficient use of water in building mechanical systems” with IAPMO’s “WE-Stand” (“Water efficiency and sanitation standard”) to offer complimentary water efficiency guidance and references in one publication.
ASHRAE 191P provides minimum requirements for the design of building mechanical systems that limit the volume of water required to operate HVAC systems. WE-Stand focuses on achieving safe and efficient water use in both residential and non-residential buildings.
The co-published document will be available upon the conclusion of the 2023 WE-Stand development process, which is a 3-year cycle.
