LEED® stands for Leadership in Energy and Environmental Design. The LEED® green building certification system is the preeminent program developed by the USGBC for rating the design, construction and operation of green buildings. It is a voluntary green building rating system  which has been in the marketplace for over 10 years and is used in more than 145 countries. LEED® is formulated on the basis of 7 global impact categories – climate change, human health, biodiversity, water, sustainable materials, community and economy. It is a benchmarking system that measures energy and environmental performance in buildings. More than 35,000 projects are currently participating in the LEED® system, comprising over 6 billion square feet of construction space in 91 countries.

By using less energy, LEED®-certified buildings save money for families, businesses and taxpayers; reduce greenhouse gas emissions; and contribute to a healthier environment for residents, workers and the larger community.

In 2012, TTGBC began a series of LEED® Green Associate Exam Preparation Training Sessions. These are 6-week, 12-contact hour programs, including access to 700 practice test questions. Past sessions were conducted September - October 2012, June - July 2013 and February - March 2014. 32 attendees have completed the training so far.
