ASHRAE and the International Association of Plumbing and Mechanical Officials (IAMPO) have announced an agreement to co-publish a document to address water efficiency in buildings.

The comprehensive document will combine ASHRAE”s Standard for the Efficient Use of Water in Building Mechanical Systems with IAPMO’s Water Efficiency and Sanitation Standard to offer complimentary water efficiency guidance and references in one publication.

ASHRAE’s standard provides minimum requirements for the design of building mechanical systems that limit the volume of water required to operate HVAC systems. IAPMO’s focuses on achieving safe and efficient water use in both residential and non-residential buildings.

“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.”

“We’re excited to coordinate our development efforts with ASHRAE,” said Dan Cole, IAPMO senior director of technical services. “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.”

The co-published document will be available upon the conclusion of IAPMO’s 2023 Water Efficiency and Sanitation Standard development process, which is on a three-year cycle.

IAPMO works in combination with governments and the industry for safe, sanitary plumbing and mechanical systems. Learn more about IAPMO at www.iapmo.org.

Founded in 1894, ASHRAE is a global professional society committed to serving humanity by advancing the arts and sciences of HVAC, refrigeration, and allied fields. It and its members are dedicated to promoting a healthy and sustainable built environment for all, through strategic partnerships with organizations in the HVAC&R community and across related industries.

The Society is showcasing integrated building solutions and sustainability in action through the opening of the ASHRAE Global Headquarters building in metro-Atlanta, Georgia. The state-of-the-art, high-performing net-zero-energy efficient global headquarters building is a destination venue for industry representatives, visiting from around the world, who are looking to experience cutting-edge engineering and architectural interventions.
