ASHRAE 188 Screening
Notes for Use:

Review each building on campus.  Place the building name in the far left column.  Check the columns that apply to the building, and you will determine which sections of ASHRAE 188-2015 Legionellosis:  Risk Management for Building Water Systems apply to your buildings. Note that ASHRAE 188 is not a current code or regulatory requirement (excluding August 2015 DOH cooling tower regulations).  It may, however, assist in prioritizing and addressing water-related Legionella concerns.
