ASHRAE, IAPMO Agree to Co-Publish ASHRAE Standard 191 and WE•Stand™

ASHRAE and the International Association of Plumbing and Mechanical Officials (IAPMO) have agreed to co-publish ASHRAE 191, a water-efficiency standard pertaining to mechanical system efficiency in buildings, with the IAPMO Water Efficiency and Sanitation Standard (WE•Stand™). The two standards’ scopes are complementary, and co-publishing will provide users with the opportunity to reference and apply both documents in one publication.

“We’re excited to coordinate our development efforts on WE•Stand with ASHRAE’s 191 Committee,” said Dan Cole, senior director of Technical Services and WE•Stand secretariat. “With the development cycle for 2020 now finalized, we will look forward to ensuring that both standards eliminate any conflicts toward achieving high levels of water efficiency for both mechanical and premise plumbing systems.” 

“Water efficiency and energy conservation are major considerations in the design and operation of HVAC systems in high-performance buildings,” said 2020-21 ASHRAE President Charles E. Gulledge III, P.E. “Escalating costs and concerns regarding availability have brought much-needed attention to the issue of water use in the built environment. We are pleased to collaborate with IAPMO to provide a balanced resource to the water-energy nexus as the demand for sustainable strategies grows.”

The co-published document will be available upon the conclusion of the 2023 WE•Stand development process, which is on a three-year cycle.

The International Association of Plumbing and Mechanical Officials (IAPMO) works in concert with government and industry for safe, sanitary plumbing and mechanical systems. Learn more about IAPMO at www.iapmo.org.
