Leadership in Energy and Environmental Design

What is LEED?

  • Leadership in Energy and Environmental Design® (LEED) is a building rating system that is recognized as the international mark of excellence for green buildings in over 160 countries.

What benefits are gained?

  • LEED recognizes that sustainability should be front and center of all buildings – in their design, construction and operation.
  • Green buildings create a healthier indoor environment for occupants through better indoor air quality, less harmful products, and more natural daylight.
  • Reduction in waste, conservation of energy, decrease in water consumption, and innovation drive are other benefits.
  • Bottom line positive effects and boost in productivity.


  • GEP can assist you in meeting the new LEED v4 standard. Some of the major changes include:
    • To qualify for LEED v4 Indoor Air Quality (EQ) Credit, building owners must meet a new set of criteria, including a comprehensive list of specific VOCs that need to be quantified in addition to total VOCs.
    • Labs will no longer be allowed to analyze for formaldehyde using TO15 evacuated canisters or TO17 (thermal desorption tubes)
    • 4-PCH is no longer required
    • The IEQ credit is now worth 2 points
    • GEP will provide the necessary equipment, testing capabilities and analytical expertise in order to help define your testing needs and assist with the implementation of your LEED IEQ management plan.
  • Contact GEP to schedule a free consultation to determine what type of contaminants are of concern and what is the most effective type of testing you need to achieve your goals.
