Three green rating systems for existing smart cities, affordable housing and interior design projects across the country were launched at the Green Building Congress 2017 organised by CII-India Green Building Council (CII-IGBC). Developed by IGBC, the rating systems aim to provide designers, builders and architects guidelines to apply green concepts in built areas and so achieve measurable, positive environmental impacts.
The IGBC Green Cities (Existing Cities) Rating System aims to create guidelines for existing and brownfield cities identified for the Centre’s Smart/AMRUT Cities program. Greening existing cities can reduce peak power demand by 10-12 percent, lighting consumption by 25-30 percent, and water consumption by 15-20 percent.
The IGBC Green Affordable Housing Rating system is the first-of-its-kind rating system to address sustainability and promote higher living standards for occupants across all strata of society. The Green Affordable Housing Rating is applicable for housing projects designed with carpet-area less than or equal to 60 sq.m per dwelling unit, which constitute at least 70 percent of the total project built-up area throughout India.
“We hope that a billion sq ft would be coming in from the Green Cities (Existing Cities) rating,” said V Suresh, Chairman, Policy & Advocacy Committee, IGBC.
Commenting on the rating, K Sriram, IGBC Executive Committee Member, said at least 25 percent to 30 percent of the 1.2 crore affordable houses to be constructed under the Affordable Housing for All by 2022 are likely to come under the Green Affordable Housing Rating.
The event also saw ‘Platinum’ green rating status awarded to five metro corporations across India – Delhi Metro Rail Corporation Limited, Chennai Metro Rail Limited, Kochi Metro Rail Limited, L&T Metro Rail (Hyderabad) Limited, and Lucknow Metro Rail Corporation Limited. Jaipur and Secunderabad railway stations also earned silver rating status.
Additionally, over 130 green building projects across the country were recognized for adhering to sustainability metrics including water and energy efficiency, reduction in fossil fuel use, handling of consumer waste and conservation of natural resources. These projects include government buildings, commercial, office, residential, factory, hotel, hospital, bank, IT park, school, airport and metro buildings.
The 3-day CII-IGBC Green Building Congress 2017 held between October 5–7, 2017 was attended by participants from 31 countries' World Green Building councils. The event featured an exhibition on green materials, products and technologies, along with focus sessions on healthcare, schools, homes and affordable housing.
