GRIHA Rating Systems, Know The 9 Different Types

You will be surprised to know? The areas valued maximum for the sale or purchase of Real Estate are the greenest parts of a city – And i.e. applicable across the globe. But why? For one simple reason these areas offer the best quality of life (with respect to cooler climates, clean air, ample ground water, ample wind-flow, natural lighting, rich flora and fauna, recreation, etc.)

Sadly, for the past few decades we have been designing buildings that typically work towards detaching the internal from the external environment – resulting in massive energy consumption. This trend demands active resolution, because of its negative environmental impact and to create a good future for the upcoming generations, our towns, cities and our country.

To provide the best quality of life to the inhabitants, a building needs to efficiently consume resources for its construction and operation. In our country, a well-planned and designed building structure is constructed out of concrete and bricks, having a life of up to 100 years. During this span, a building structure typically consumes natural resources and generates waste in unthinkable quantities. This is a serious issue, a building needs to reduce their waste generation and resource consumption with immediate effect.

For the past few years, the expression ‘Green Buildings’ is uninterruptedly monopolizing limelight in the media. Simply put, Green Buildings are structures which ensure efficient use of natural resources like building materials, water, energy and other resources with minimal generation of non-degradable waste. But Who Decides A Green Building Is Really Green?

This is decided against the predefined rating systems. In India, the below mentioned are the primary Rating systems.

  • GRIHA (Green Rating for Integrated Habitat Assessment)
  • BEE (Bureau of Energy Efficiency)
  • IGBC (Indian Green Building Council)
  • LEED India (Leadership in Energy & Environmental Design)

In this blog we will be exclusively discussing the GRIHA Rating system.

GRIHA – Green Rating for Integrated Habitat Assessment

griha rating

GRIHA is India’s own Green Building rating system conjointly developed by TERI and the Ministry of New and Renewable Energy, Government of India.

This is a green building design evaluation system where building structures are rated in a 3-tier process. Typically, the process begins with online submission of documents based on prescribed criteria followed by physical on-site visit and evaluation of the structure by a team of experts and professionals from GRIHA Secretariat.
