Glass and Green Ratings

Green Building Rating Systems in India 

A green building rating system is a tool that evaluates the performance of a building and its impact on the environment. It comprises a predefined set of criteria relating to the design, construction, and operations of green buildings. 

In India, there are predominantly three rating systems – Leadership in Energy and Environmental Design (LEED), the rating systems from Indian Green Building Council (IGBC) and the Green Rating for Integrated Habitat Assessment (GRIHA). In addition, there is also the Energy Consumption Building Code (ECBC) and the National Building Code (NBC), which provide guidelines on energy consumption. All buildings in India need to comply with these prescribed guidelines.

Role of Glass in Green Rating

LEED and GLASS

LEED, or Leadership in Energy and Environmental Design, is a green building certification program that recognizes top-notch building strategies and practices. Glass plays an important role in LEED certification and can significantly impact a building’s rating. LEED certified buildings save money and resources, and have a positive impact on the health of occupants, while promoting renewable energy.

GRIHA and GLASS

GRIHA, or Green Rating for Integrated Habitat Assessment, is a rating tool that assesses the performance of a building against certain nationally acceptable benchmarks. Developed by TERI and adopted by the Indian Government in 2007, it serves to carry out a qualitative and quantitative assessment and accordingly rate a building on its level of ‘greenness’.

IGBC and LEED

The United States Green Building Council (USGBC) is best known for its initiative called LEED (Leadership in Energy and Environmental Design) – a globally acclaimed green building rating system.

LEED provides third-party verification that a building or community has been designed and built using strategies aimed at improving performance across all metrics: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources.

The Indian Green Building Council, which had adopted the LEED system, has now launched nine new rating systems of its own.

LEED Criteria

Projects that are being assessed for LEED certification earn points on the basis of six broadly defined LEED credit categories. Projects are rewarded LEED points for complying with these specific green building criteria as well as satisfying prerequisites within the categories.

The six LEED categories are:

  • Sustainable sites
  • Water efficiency
  • Energy and atmosphere
  • Materials and resources
  • Indoor environmental quality
  • Innovation in design

LEED Certification

A point-based system, LEED certification is available across 4 levels. The relevant LEED certification is granted based on the number of points a project earns.

GRIHA Rating System

GRIHA, or Green Rating for Integrated Habitat Assessment, is a rating tool that assesses the performance of a building against certain nationally acceptable benchmarks. Developed by TERI and adopted by the Indian Government in 2007, it serves to carry out a qualitative and quantitative assessment and accordingly rate a building on its level of ‘greenness’.

GRIHA currently operates under ADARSH (Association for Development and Research on Sustainable Habitats) and is supported by the National Advisory Council (NAC) and Technical Advisory Committee (TAC).

What does GRIHA do?

  • Evaluate the environmental performance of a building over its entire life cycle
  • Provide a definitive standard for what constitutes a green building
  • Follow best practices along with national and international codes applicable to the green design of buildings
  • Achieve efficient resource utilization
  • Enhance resource efficiency and better quality of life in buildings

GRIHA Criteria

The set of 34 GRIHA criteria are broadly classified into four categories:

  • Site selection and site planning
  • Building planning and construction
  • Building operation and maintenance
  • Innovation
  • These four categories are further classified into mandatory, optional, applicable, and selectively applicable.

GRIHA Certification

All buildings in the design stage, except for industrial complexes and housing colonies, are eligible for certification under the TERI GRIHA system as follows:
