Materials, Indoor Environmental Quality, and the Certification Process

Materials

  • Prerequisites: certified tropical wood (FSC or equivalent, or none used) and a durability management process, with water-management details documented and verified on site.
  • Credits: material-efficient framing and framing-waste optimization; construction waste management with debris diversion; environmentally preferable products such as FSC wood, recycled content, bio-based materials, and local sourcing.

Indoor environmental quality

  • Prerequisites: combustion venting (no unvented combustion appliances; sealed or power-vented equipment), garage pollutant protection (no air handler or ductwork in the garage, sealed and exhausted garage), radon-resistant construction in high-risk zones, and MERV filtration on central systems.
  • Credits: enhanced ventilation (kitchen and bath exhaust to outdoors, quiet ENERGY STAR fans, verified airflow), enhanced compartmentalization in multifamily, low-emitting materials with VOC limits for adhesives, sealants, paints, flooring, and composite wood, and contaminant control such as sealed ducts and walk-off mats.

Certification process

  • Register the project in LEED Online and contract a LEED Green Rater through a Provider.
  • Verification runs in two stages: a preliminary rating at design, then a final inspection after construction, both behind Provider quality assurance.
  • Submittals include HERS and ENERGY STAR files, the durability checklist, photographs, invoices, and rater field reports.
  • Certification is awarded at 40, 50, 60, or 80 points, and appeals exist for disputed credits.

Worked example

A builder uses FSC joists, diverts 60% of construction debris, installs a sealed-combustion furnace with a MERV 13 filter, and keeps the air handler out of the garage. That earns materials and waste points while clearing combustion venting, air filtering, and garage protection at once.

Traps that cost marks

  • Thinking low-VOC paint alone earns the materials credit.
  • Routing return-air ductwork through the garage - an automatic prerequisite failure.
  • Believing the builder can self-certify; only the Green Rater verifies.
