EQ Credit: Low-Emitting Materials

  • Ensure that the appropriate category and/or product type is selected for each material listed in the Low-Emitting Materials Calculator (Products tab).
  • For the Budget Calculation Method, ensure that the assembly name provided on the Low-emitting Materials Calculator is a unique identifier for the assembly in which the product is a part (e.g. Wall Type 1A). Note that each product within an assembly will have the same assembly name. This will enable the grouping of the assembly in the calculation. If a product is included within more than one assembly, it may be listed more than once.
  • Ensure that all of the flooring, ceiling, wall, thermal, and acoustic insulation assemblies used on the project have been included in the Low-Emitting Materials Calculator. To ensure that all installed products are listed, cross check the project specifications, Calculator, and general project documents (floor and ceiling plans, elevations, connection details, photographs, etc.). Each assembly should have several components listed.
  • Confirm that the descriptions of materials in the Low-Emitting Materials Calculator (Products tab) match the manufacturers' naming conventions of the products or materials.
  • Ensure that manufacturer or testing documentation demonstrates that the applicable sustainable criteria are met for each product.
  • For projects outside of the U.S. including products tested using AgBB or ISO methods, ensure that manufacturer documentation demonstrates that the products meet the French VOC emissions class labeling of A+ or do not exceed a formaldehyde limit of 10 µg/m3 at 28 days.
  • Ensure that the general emissions evaluation reports state the exposure scenario used to determine compliance and the measurement of TVOCs.
  • Ensure that the VOC content documentation states that testing follows the test method specified in the applicable regulation and that this information is highlighted.
  • For wet-applied products in the VOC content section of the Low-Emitting Materials Calculator, ensure that the volume used has been included for every wet-applied product (unless 100% of the products are compliant). Alternatively, the "volume used" column may be completed for enough of the wet-applied products to determine budget compliance.
