LEED Rating System

Leadership in Energy and Environmental Design (LEED) is the most widely used Green building rating system in the world. LEED certification for a building symbolizes how sustainable the building is throughout its life cycle in terms of resource use, energy efficiency and conservation, water efficiency and choice of building materials.

LEED rating system focuses on eight credit categories namely (i) Location & Transport, (ii) Sustainable Sites, (iii) Water Efficiency, (iv) Energy & Atmosphere, (v) Materials & Resources, (vi) Indoor Environmental Quality, (vii) Innovation and (viii) Regional Priority. Each of these credit categories consists of prerequisites and credit points required to achieve LEED rating. The LEED rating for a building can be achieved in four levels namely
1. Certified: 40-49 credit points; 2. Silver: 50-59 credit points; 3. Gold: 60-79 credit points;
4. Platinum: 80+ credit points.
Benefits of LEED Rating System
Sustainable buildings are the need of the hour in current situation in a world influenced by increased water and energy use, depletion and exhaustion of valuable resources. Studies shows that buildings account for 40% of the global energy use, 19% of energy related greenhouse gas emissions, and approximately one-third of the carbon emissions. Design and development of sustainable buildings not only reduces the use of resources but also paves way for a positive impact on the environment. Some of the benefits of a LEED certified buildings are as follows:
 LEED certification are universally recognized and creates a good example to clients, neighbours and family on the positive impacts of a sustainable building;
 LEED certified buildings consumes relatively less amount of energy and water throughout its life cycle thereby reducing the environmental footprint;
 One of the key aspects of LEED building certification is its emphasis on indoor air quality. Studies shows that Indoor air in most buildings which are not LEED certified are polluted. LEED certified buildings eliminate the pollution levels in the indoor air through effective HVAC designs;
 LEED certified buildings relatively uses less hazardous building materials for their construction and also emphasize on the use of materials with less volatile content. It also prohibits the use of certain hazardous materials to be used in the building construction;
 LEED certified buildings promotes the use of sustainable transportation and tries to reduce transportation through privately owned automobiles by providing accessibility to facilities and amenities nearby the building. It also emphasize on the use of green vehicles and use of public transport system which in turn reduces the environmental footprint.

GE3S has a dedicated team of LEED qualified professionals with broad experience on multiple projects spanning across several countries. GE3S’s experienced staffs are well versed in the practical and cost effective application of LEED in the unique climate and context of the various part of world. Team’s experience and the lessons learned from the process is extremely valuable when assisting project teams in achieving the desired LEED rating in the most effective manner.
