  IEQ Credit 3.2: Construction Indoor Air Quality Management Plan—Before Occupancy

Want another reason why the use of tile can be a wise choice for interior finishes in green building projects? Once installed, tile products have a much more positive effect on indoor air quality than competitive surface coverings. If the overall indoor air quality is measurably good enough subsequent to the installation of all interior finishes, occupancy can commence virtually immediately. In fact, steps towards improved indoor air quality prior to occupancy can assist in creating an IAQ management plan that complies with option 2 of LEED® IEQ Credit 3.2 (1 point). Such a plan involves IAQ testing prior to occupancy that is much quicker and more efficient than the "building flush-outs" required in option 1.

The requirements for this plan and the advantages gained when using tile are as follows:

 
Demonstrate that the maximum concentration levels listed below are not exceeded.
Contaminant Maximum Concentration Benefit from Using Tile
Formaldehyde 27 parts per billion Tile products do not emit formaldehyde.
Particulates (PM10) 50 micrograms per cubic meter Wet saws and snap cutters result in minimal airborne dust; dust-free technology of grouts and mortars helps minimize particulates.
Total Volatile Organic Compounds (TVOCs) 500 micrograms per cubic meter Tile has zero VOCs; most tile installation products have little to no VOC emissions.
4-Phenylcyclohexane (4-PCH) 6.5 micrograms per cubic meter This test only required if carpets or fabrics with styrene butadiene (SBR) rubber latex backing are installed; tile has no impact in this category.
Carbon Monoxide (CO) 9 part per million and no greater than 2 parts per million above outdoor levels Tile installation does not involve the use of CO emitting tools.
