Indoor Air Quality

Steve Li gave a presentation on indoor air quality, then led a discussion of specific cases faced by the audience.

In his presentation, Steve identified four main IAQ contributors:

  1. Outdoor sources.
  2. Indoor sources.
  3. HVAC design and performance.
  4. Occupant characteristics/needs (age, job stress, computer use, etc.).

Occupant perception of whether indoor environmental conditions meet their needs results from the multi-factorial interplay of these four main contributing factors. Currently, there are no OSHA regulations governing indoor air quality, and it is not likely that we will see any. ASHRAE 62-1999 ("Ventilation for Acceptable Indoor Air Quality") is a primary engineering reference available on this subject.

When confronted by an IAQ complaint, some of Steve's recommendations are to remain open minded, to show due diligence in your response, and "communicate, communicate, communicate" (involve as many potential stakeholders as possible). Steve distributed a list of potentially helpful literature references and articles relevant to current IAQ issues. He has additional copies on request (206-763-7364; sli@claytongrp.com).

HELP members discussed many different examples of indoor air quality complaints, ranging from bad perfume to the improper placement of intake/exhaust ports. Solutions included "no reapplication of fragrance" policies, maintaining 30-65% relative humidity, performing physical inspection of HVAC components, and enumerating IAQ responsibilities in tenant leases.
