What is the point system for LEED?

The point system is a way to measure the sustainability of a building in the categories of site, water, energy, materials, indoor environmental quality, innovation and regional priority. Based on a total of 110 points, a project can achieve the level of basic LEED certification by achieving 40-49 points, LEED silver certification by achieving 50-59 points, LEED gold certification by achieving 60-79 points and LEED platinum certification by achieving 80-110 points.
