Olfactory comfort

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.

This feature supports building policies that discourage strong smells from chemicals and fragrances, striving to keep interior environments odorless.

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:

a. Negative pressurization.
b. Interstitial rooms.
c. Vestibules.
d. Hallways.
e. Self-closing doors.
