CMRL gets LEED Gold Rating

The headquarters and the maintenance depot of the Chennai Metro Rail Ltd have received gold rating under Leadership in Energy and Environmental Design (LEED). LEED is the most widely used green building rating system in the world. LEED provides a framework to create healthy, highly efficient and cost-saving green buildings and LEED certification is a globally recognized symbol of sustainability achievement.

CMRL’s structures were evaluated based on the sustainable sites, water efficiency, energy and atmosphere, material and resources, indoor environmental quality, innovation in design and regional priority credits. The various components were assessed on the basis of design, construction, operation and maintenance to ascertain the environment friendliness of the structures and effective use of resources. The headquarters and the maintenance depot scored 70 out of 110 points and became eligible for Gold Rating under LEED 2009.

Projects pursuing LEED certification earn points across several categories, including energy use and air quality. Based on the number of points achieved, a project then earns one of four LEED rating levels: Certified, Silver, Gold or Platinum. When a project scores more than 80 points it becomes eligible for Platinum Rating which is the highest LEED rating.
