ASHRAE Guideline 12-2000, Minimizing the Risk of Legionellosis Associated With Building Water Systems, is open for a 45-day public review concluding Sept. 11.

ASHRAE Guideline 12-2000, Minimizing the Risk of Legionellosis Associated With Building Water Systems, is open for a 45-day public review concluding Sept. 11.

Developed by ASHRAE Standing Standard Project Committee (SSPC) 188, ASHRAE Guideline 12 is intended for use by owners of human-occupied buildings and those involved in the design, construction, installation, commissioning, management, operation, maintenance, and service of centralized building water systems and components.

In addition to providing essential information and guidance to assist in the control of Legionellosis associated with building water systems, ASHRAE Guideline 12 gives users direction in implementing ASHRAE Standard 188, Legionellosis: Risk Management for Building Water Systems.

“Our goal with Guideline 12 is to have a strong companion document that works in tandem with ASHRAE Standard 188,” Michael Patton, member of ASHRAE SSPC 188, said. “We invite all interested and affected parties to review and comment on Guideline 12 during its public-review period. Doing so will help ASHRAE and SSPC 188 create better resources that help building owners minimize the risk of Legionellosis.”

The Centers for Disease Control and Prevention estimates there are between 8,000 and 18,000 cases of Legionnaires’ disease in the United States each year, with more than 10 percent of the cases fatal. Most are the result of exposure to Legionella associated with building water systems.

ASHRAE Guideline 12 is a continuous-maintenance guideline with updates planned for publication every three years. For more information and to comment, go to www.ashrae.org/publicreviews.
