Thelow-flow fixtures in bathrooms, use of Forest Stewardship Council (FSC) certified wood, and a water usage standard 33% lower than the LEED Platinum baseline are some of its sustainability achievements.
Guwahati Neurological Research Centre (GNRC), Assam
GNRC, founded in 1987 by Nomal Chandra Borah, is the first green hospital in North East India. The bamboo cladding was used in the construction of building’s exterior. This bamboo cladding acts as a natural insulator and allows the hospital to do away with the air-conditioning in lobbies and reception, thus resulting in saving electricity and reducing maintenance cost.
The building incorporates green features like effective water management by using efficient irrigation systems and STPs. It also uses Low-flow plumbing fixtures. T5 & CFL lightings throughout the hospital save significant energy annually.Efficient HVAC results in huge energy savings and comfort. Solar Street Lamps have also been installed in GNRC to reduce external lighting energy consumption.Low Emitting Materials- Paints, Sealants & adhesives been used.
