46 countries and territories, along with the 50 states are represented in the voting pool for LEED changes. The new LEED rating system will launch in November at the Greenbuild conference in Philadelphia, PA. There are currently over 100 projects pursuing LEED v4 certification in its Beta program, and these buildings will seek review as early as this summer.
LEED v4 was open to discussion throughout this year, with the public providing input and invaluable feedback. Some of the major changes from LEED 2009 included:
- LEED BC+C has new compliance paths for hospitality projects, data centers, warehouses, and distribution centers
- LEED EB O+M has new compliance paths for schools, retail, data centers, warehouses, and distribution centers
- "Location and Transportation" has been added as a new credit category
- New prerequisite for water metering and a new credit for cooling tower water
- Indoor Environmental Quality, Outdoor Air Delivery Monitoring, and Increased Ventilation are now one new credit called "Enhanced Indoor Air Quality Strategies."
- New credits for regional and reused materials including "Material Ingredient Reporting," "Avoidance of Chemicals of Concern," and "Responsible Extraction of Raw Materials."
