Errata Sheet for ASHRAE 170: Ventilation of Health Care Facilities


Addenda to ASHRAE 170-2008

The 2008 edition of ANSI/ASHRAE/ASHE 170 was incorporated into the 2010 edition of the FGI Guidelines. ASHRAE has placed Standard 170 under its continuous maintenance process, which means adjustments can be made to it between publication dates.

These changes go through the same rigorous review process as the originally published material, and it is the intention of the Health Guidelines Revision Committee that these addenda be considered a part of the 2010 FGI Guidelines. Addenda that have received final approval and are posted on the ASHRAE website include:

Design temperature for NICU, and other changes. [PDF download]

Updates to design parameters for critical care, laboratories, and endoscopy; addition of design parameters for intermediate care; and other changes. [PDF download]

Humidity levels in short-stay patient areas, including operating rooms. [PDF download]

Meaning of “occupied space” and other changes. [PDF download]

Requirements for AII and PE rooms and a combined AII/PE room. [PDF download]
