  • Did You Know?

    Green building standards are constantly being added or updated, such as from the International Green Construction Code (IGCC) and Green Globes. Certain states and localities may have their own standards. In addition, even LEED has proposed Version 4 with stricter air quality standards. Know the standard that your building is trying to achieve. Contact EHS Innovators for the most cost-effective methods of testing.

    LEED Indoor Air Quality Testing

    LEED, the Leadership in Energy and Environmental Design standard developed by the U.S. Green Building Council (USGBC) is a rating system providing standards for environmentally sustainable construction. Credits toward building LEED certification can be earned by conducting Indoor Environmental (IEQ) Quality or Indoor Air Quality (IAQ) testing for certain common building contaminants specified in the standard. While the testing is usually optional and the standards are strict, an organization would be hard pressed to legitimately claim they have a "green" or sustainable building if good air quality to the occupants is not part of the certification.

    EHS Innovators offers certified, experienced professionals, such as Certified Industrial Hygienists (CIH), to guide your AP through the process and perform the IEQ testing. This includes consultation before testing on steps to take to ensure passage of the tests. EHSI also offers optional analytical testing to help identify the cause of any test failures, so that those conditions can be corrected with subsequent retesting if necessary.

    To pass these tests:

    • Measurements must be completed prior to occupancy, but during normal occupied hours, with the building ventilation operating at the normal start and stop times at the minimum outside air flow rate throughout testing;
    • Test protocols must be consistent with or equivalent to the USEPA Compendium of Methods for the Determination of Air Pollutants in Indoor Air;
    • All interior finishes must be in place at the time of testing; non-fixed furnishings (e.g., workstations, partitions) are encouraged but not required;
    • IEQ samples must be collected in representative portions of the building served by each separate air handling system covering no more than 25,000 square feet or one contiguous floor space, whichever is larger; and
    • Samples must be collected for a minimum duration of four (4) hours, 3' - 6' above the floor.

    Air quality testing is a specialized science requiring a thorough understanding of methods and interpretation of results. Low bid air quality technicians often propose improper (cheaper) test methods, such as using direct-reading instruments to measure VOCs and dust that are not consistent with USEPA Compendium methods. Often these "oversights" are not discovered until months later after the building is occupied and the window for testing has expired. As a result, the use of improper methods can waste your time, money and jeopardize your LEED certification.
