ANSI/ASHRAE Standard 170-2017 Ventilation of Health Care Facilities

ANSI/ASHRAE Standard 170-2017 Ventilation of Health Care Facilities offers guidance, regulation, and mandates to designers of health care facilities. The revised 2017 edition incorporates 12 addenda to the 2013 standard and includes the following significant changes:

• Addition of adiabatic humidifiers as an acceptable type
• Addition of a new type of exam room with lower requirements for less-acute applications
• Clarification around the prohibition of controls to change pressure relationships between spaces
• Reduction in requirements for electroconvulsive therapy procedure rooms
• Reduction in requirements for laboratories when allowed by certain calculations
• Higher requirements for higher hazard exhaust airstreams
• Coordination of space temperature requirements in the Sterile Processing Department with other industry groups
• Clarification of the definition of the primary diffuser array in operating rooms

The standard has also been reorganized into three sections: hospital spaces, outpatient spaces, and nursing home spaces. These changes were made to bring Standard 170 into alignment with the forthcoming 2018 FGI Guidelines.
