ASHRAE 514-2023

ANSI/ASHRAE Standard 514, Risk Management for Building Water Systems: Physical, Chemical, and Microbial Hazards, establishes minimum requirements for managing risk associated with building water systems and provides a framework for the systematic development of water management programs, from design and construction to occupancy, including post-occupancy modifications and renovations.
The standard is intended for use by owners and managers of human-occupied buildings and those involved in the design, construction, installation, start-up, operation, maintenance, and service of centralized building water systems and components.
Standard 514 is consistent with the structure and methodology of ASHRAE Standard 188 and requires its use for legionellosis risk management. Implemented together with ASHRAE Guideline 12, these standards address the need for management of overall risk from physical, chemical, and microbial hazards associated with building water systems.
