Last Saturday, the Council of Scientific & Industrial Research’s (CSIR) National Environmental Engineering Research Institute (NEERI) of India has constructed a new green building in its premise. It is the first local building to be registered under Griha, a scheme launched by the Ministry of New and Renewable Energy, and received a four-star rating for its green features. The ceremony was inaugurated by the Union minister of state for chemical and fertilizer Hansraj Ahir.
Constructed at the cost of 5 crore with 2024.40 sq mtr total area and 1132 sq mtr built area, the institute is equipped with state-of-the-art molecular marker laboratory for source apportionment studies, analytical laboratory for air quality monitoring and also atmospheric dispersion modelling laboratory.
According to AS Dubey, NEERI superintending engineer and project leader, the next building up for construction will continue to be green-certified. He added that it is NEER’s duty to adopt the green building concept mostly because they are a government body and would like to stand as a role model to all.
According to Bhooshan Kotwal, the owner of the Bhooshan Kotwal Architects and BSNL,the exterior of the building looks like an attractive glass building. The main intention of the building developers was to reduce and minimize electricity and water usage by 30% and 60%, respectively. But also, use maximum light and still maintain indoor temperatures.
To reduce heat brought about by India’s strong tropical climate, the west side of the building has been designed with minimum punctures and a double wall with cavity in between.
70% of the material used in construction were recyclable material, such as bricks made in fly-ash and recyclable autoclaved aerated concrete (ACC). Moreover, the soil excavated in the pre-construction process had been used later during the building construction. Remains of cement slurry were also reused fully, as been explained by Shon Kotwal, one of the partners at the firm.
