Helping business owners and facilities managers navigate sustainable savings

The American Society of Heating , Refrigerating, and Air Conditioning Engineers or ASHRAE released a new standard in 2015 relating to Legionella prevention. Known specifically as ANSI/ASHRAE Standard 188-2015, the standard targets an intended audience of individuals that maintain and manage building water systems.
