Green Building Rating Systems


-Dr. Rohan Dasgupta

2. Introduction
●Green building rating systems are frameworks that assess and certify the environmental
performance of buildings.
●These systems are designed to:
○ promote sustainable construction practices,
○reduce environmental impact, and
○improve the overall efficiency and performance of buildings.
●Different countries and regions have their own green building rating systems, but many share
common principles.

3. Evolution of Green Building Rating Systems
●1990: BRE launched BREEAM (UK)
●2000: USGBC launched LEED (US)
●2001: CII launched IGBC (India)
●2002: GBCA launched Green Star (Australia)
●2003: TERI launched GRIHA (India)
●2010: IFC introduced EDGE

4. Evolution of Green Building Rating Systems
●Shift in focus of Green Building Rating Systems:
○2014 - well being standards
○2015 - life cycle analysis
○2020 - net zero initiatives (energy, water & waste)
○2024 - circular economy
