Farmer Environmental Group has successfully completed a New Construction LEED IAQ survey of a commercial building in Central Texas. The purpose of the New Construction IAQ Management Plan is to prevent indoor air quality problems resulting from the construction process in order to sustain the comfort and well-being of the building occupants and the construction workers. The IAQ testing provides verification that major contaminants are below recognized acceptable levels prior to occupancy.

Air testing under this plan is a required component of the project LEED strategy.  Air testing was used to determine concentrations of certain chemical components following the completion of new construction activities and prior to occupancy of the site. Air samples were collected to identify and document chemical component levels within the construction area and the exterior for CO comparison. The following chemical components were tested and analyzed for comparison with the maximum allowable levels:

ContaminantMaximum Concentration
Formaldehyde50 parts per billion
Particulates (PM10)50 micrograms per cubic meter
Total Volatile Organic Compounds (TVOC)500 micrograms per cubic meter
4-Phenylcyclohexene (4-PCH) *6.5 micrograms per cubic meter
Carbon Monoxide (CO)9 parts per million and no greater than 2 parts per million above outdoor levels
*This test is only required if carpets and fabrics with styrene butadiene rubber (SBR) latexBacking material are installed as part of the base building systems.
