ASHRAE Standard 170 - Healthcare Ventilation UPDATES
The ASHRAE 170 Committee—focused on ventilation standards in healthcare-- met at the annual ASHRAE winter conference. Several significant changes are coming that will impact engineers, architects, and owners if implemented. The following are some highlights...
Healthcare Ventilation Standards: "One Size Does Not Fit All"
ASHRAE issued this Addendum for what is called “Advisory Public Review”. (i.e. ASHRAE will not necessarily take any particular actions in response to comments received.) They are using this opportunity to collect thinking on the basic soundness of the concepts and identify any big gaps they can fill prior to issuing it for actual public comment.
Healthcare Ventilation Standards: Why More Research is Needed
Our hypothesis, though controversial for some, is that we frequently over-ventilate spaces. We don’t truly understand ‘why’ the standards prescribe a certain number of air changes. As a result, hospital owners (likely) are wasting energy dollars without improving indoor air quality.
