April 2, 2019 – ASHRAE announced its intent to continue development of a standard to establish safe management practices for building water systems. NSF International recently transferred facilitation of NSF Standard 444, Minimizing Risk of Disease and Injury Associated with Building Water Systems, to ASHRAE to complete the standard development process and publish it as ASHRAE Standard 514.

Proposed ASHRAE Standard 514 will be designated as a safety standard. The committee will coordinate with SSPC 188, Legionellosis: Risk Management for Building Water Systems, to ensure there is no conflict or duplication between the two standards. Where appropriate the document will reference ANSI/ASHRAE Standard 188-2018, Legionellosis: Risk Management for Building Water Systems. 

ASHRAE Standard 514 will provide methodology covering the prevention of injury and disease from Legionella as well as other waterborne pathogens, chemicals and physical hazards.

“Standard 514 will go further to address building water quality, the importance of managing safe, quality building water systems and prevention strategies,” said 2018-2019 ASHRAE President Sheila J. Hayter, P.E.

ASHRAE is accredited by the American National Standards Institute (ANSI) to develop voluntary standards and both are required to comply with ANSI’s Essential Requirements for openness, balance, consensus and due process. While ASHRAE will facilitate development of the standard, the actual content of the standard will continue to be developed by a committee of stakeholders from academia, public health, regulatory and industry sectors.
