Basic certification requires 40-49 points, silver 50-59 points, gold 60-79 points, and 80+ points for platinum certification. [5] Points are also available within the LEED for Neighborhood Development rating system for having certified green buildings in the development and for integrating green building and infrastructure practices within the ...
The pilot version, LEED New Construction (NC) v1.0, led to LEED NCv2.0, LEED NCv2.2 in 2005, LEED 2009 (a.k.a. LEED v3) in 2009, and LEED v4 in November 2013. LEED 2009 was depreciated for new projects registered from October 31, 2016. [58] LEED v4.1 was released on April 2, 2019. [59]
The LEED Green Building Rating System (LEED) is a program that provides third-party verification of green buildings. The LEED program rates commercial buildings, homes, neighborhoods, retail, healthcare, schools, including every phase of the respective building lifecycle, including design, construction, operations, and maintenance.
However both BIG and LEED are successful standards similar to CALGreen. The system developed by Build-it-Green is called GreenPoint Rated Climate Calculator and initial project run-throughs using the Climate Calculator found emissions reductions of about 20% over conventional new construction built to code.
The LEED AP exams consist of two parts, the LEED Green Associate exam and the applicable LEED AP specialty exam; each part contains 100 randomly delivered multiple choice questions and each part must be completed in 2 hours. Individuals must score at least 170 out of 200 in order to pass.

There is an implication that an LOI only refers to the final form.
Low-energy electron diffraction (LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low-energy electrons (30–200 eV) [1] and observation of diffracted electrons as spots on a fluorescent screen.
