How to Build Green »

LEED is a voluntary, consensus-based, market¬-driven program that provides third-party verification of green buildings. LEED is used for a variety of building types and is a tool for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions. The most recognized and widely used green building program across the globe, LEED certifies over 148,000 square meters of building space each day in 147 countries and territories. Today, nearly 50,000 projects are currently participating in LEED, comprising more than 800 million square meters of construction space.

How to certify your building project »

Here’s how to certify:

  1. Determine which rating system you will use and prepare your certification application. Applications differ depending on your building type and the LEED credits you decide to pursue.
  2. Register your project.
  3. Once your project is at or near completion, submit your certification application.
  4. Await the application review. Review processes differ slightly for each building type.
  5. Receive the certification decision, which you can either accept or appeal. An affirmative decision signifies that your building is now LEED certified.

Commercial LEED projects must satisfy all LEED prerequisites and earn a minimum 40 points on a 110-point LEED rating system scale. Homes must earn a minimum of 45 points on a 136-point scale.
