The American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) has developed a proposed Standard Practice that specifies what is required to prevent legionellosis associated with building water systems. The proposed Standard Practice was approved in July 2010 for public review publication. The first public review was completed in November 2010; there were many supportive comments posted and also many excellent suggestions to improve the Standard. A revision was produced in response to comments received during the public review. The second public review opened June 10, 2011 and closed July 25. This paper gives perspectives in relation to CTI Standard 159, Legionellosis Related Practices for Evaporative Cooling Water Systems, which is in process and could be public by the time of the presentation of this paper.
