Summa canister), questions remain about how to report the results. Results reported as toluene equivalent are different from
those reported as hexane equivalent. How the results are reported can affect whether the building passes or fails.
Industrial hygiene expertise can also be applied to the issue
of low-emitting materials. The “ 4” series of LEED credits addresses VOC content of building materials such as adhesives,
paints, flooring, and composite wood products.
To help educate the green building industry about the potential
role of industrial hygienists, the Occupant Air Quality Project
Team of the AIHA Green Building Working Group is preparing
a white paper titled “Indoor Air Quality in Green Buildings: An
Industrial Hygienist’s Perspective.” Our involvement can help
the designers and builders of green buildings avoid repeating
the IAQ mistakes of the past.

A White Paper for Green Building
A forthcoming white paper by the Occupant Air Quality Project
Team of the AIHA Green Building Working Group will help
those in the green building industry better understand IAQ.
“Indoor Air Quality in Green Buildings: An Industrial Hygienist’s
Perspective” will focus on LEED, particularly the inadequacies
of the two optional credit categories: the construction IAQ
management plan credits (the “ 3” series) and the low-emitting
materials credits (the “ 4” series). The goals of the white paper
include the following:
• Clarify the value of building flush-out and describe the conditions under which it might be appropriate.
• Discuss the history of Credit 3.2 Option B.
• Show that the current LEED requirements for air testing are
poorly defined regarding sampling methods and timing of
sampling, and that the specified pollutants and their allowable levels are often inappropriate.
• Discuss the appropriateness of using outdoor air-related
total VOC content limits for controlling indoor air quality,
along with alternative approaches.
The white paper will also discuss other issues that negatively
affect IAQ, including the shedding of fibrous duct lining, poor
access to ventilation systems for maintenance, and the location of sewer vents and other outdoor pollutant sources near
outdoor air intakes.
