The most recent LEED rating system came out in 2009 and contains 9 different LEED rating systems for the design, construction, and operation of buildings, homes and neighborhoods. Of the 9 rating systems, 5 categories are most commonly employed: green building design and construction, green interior design and construction, green building operations and maintenance, green neighborhood development, and green home design and construction.
In general, if buildings are accepted for LEED certification, they are given one of four statuses by the USGBC based on a 1-100 point scale. There is also a 6 point bonus for innovation in design and a 4 point bonus for regional priority. The four statuses are given below, with 1 being the least green to 100 being the most green.
Certified: 40-49 points
Silver: 50-59 points
Gold: 60-79 points
Platinum: 80 points and above
Note: These point ranges apply to most of the profiles, not all. For example, for LEED Retail, the maximum point value is 71.
