COVID-19: Are you ready for the next normal?


ASHRAE Standard 188-2015 officially released!

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has just released the long awaited industry standard on legionellosis.   The ASHRAE document states it is to be considered the “minimum” risk management standard requirements for building water systems.

ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems, provides guidance to building owners and managers as well as professionals involved with the design, construction, installation, commissioning, operation, maintenance and service of centralized building water systems and components.

According to ASHRAE, standard requirements include:

  • Minimum Legionellosis risk management requirements for buildings and their associated potable and non-potable water systems.
  • Establishment by building owners of a Program Team and (in turn) a Water Management Program for which they are responsible in order to comply with the standard.
  • Provision of specific and detailed requirements for what Legionellosis control strategies must accomplish and how they are to be documented – but, does not provide (or place restrictions on) what specific strategies are to be used or applied.

ASHRAE, founded in 1894, is a global society that focuses on building systems, energy efficiency, indoor air quality and sustainability within the industry.
