Olfactory comfort

Olfactory comfort


To maximize olfactory comfort by reducing the transmission of strong smells and odors within the building.


Excessively strong or distinct odors can disrupt physical and psychological comfort, and even trigger eye, nose and throat irritation, nausea and headaches. Limiting these odors is a simple strategy that can greatly contribute to occupant comfort and well-being.

Part 1
Source Separation

All restrooms, janitorial closets, kitchens, cafeterias and pantries prevent strong odors from migrating to workspaces through one or more of the following separation methods:
Negative pressurization.
Self-closing doors.
Hallways, vestibules or other intermediate areas.
