The Association for Development and Research for Sustainable Habitats (ADaRSH) recently presented the coveted GRIHA-Green Rating for Integrated Habitat Assessment-certificate to the Indian Railways for Rail NirmanNilayam project at Secunderabad, Hyderabad.
Rail NirmanNilayam is a G +4 storied new office building constructed for the Administrative department were the Chief Administrative Officer and his team will operate from. The building is located in the General office compound area of South Central Railway at Secunderabad. The Rail NirmanNilayam project is the first GRIHA-registered project covered under the Ministry of New and Renewable Energy incentive scheme to get the provisional GRIHA rating.
The project is spread over an area of 7800sqm, with the built up area being around 4405sqm. The complex has achieved 36.5% reduction in energy consumption as compared to the GRIHA benchmark by adopting several energy efficiency measures such as use of high performance glass, shading systems, efficient lighting, space conditioning systems and controls for lighting. The project is completed in 2011-2012 and it is the first project of the Indian Railways to be registered for GRIHA compliance.
The project is centrally located and all basic services like public transport, post office, health unit and place of worship are within half km radius. The project is well crafted with latest guidelines on earthquake forces, the road and pathway lengths are minimized to take the advantage of site circulation efficiency and aggregated utility corridors are provided for water supply pipelines, sewage pipelines, electrical cables and communication cables.
The building is designed with 40% glazing area, with two skylights to give more lighting therefore, reducing the conventional energy demand. Low energy materials like fly ash bricks, ready mix concrete and all the regionally available materials are used. The internal partitions are made of aluminum frames, particleboards, and gypsum boards for false ceiling.
To decrease the consumption of energy certain majors were implemented – like use of energy efficient light (indoor & outdoor) as per ECBC-2007, Skylight – to harness day light in dark patches rest rooms and corridors, multi sensors – compatible to DALI based dimming of lights system, use of building management system for comprehensive electrical parameters reporting, comparative and performance analysis and remotely switching ON/OFF facility for each equipment and also use of centralized air conditioning through variable refrigerant flow technology.
Further, Rainwater harvesting is provided for the full quantity of rainwater from the rooftop and circulation area. The wastewater is treated in the Sewage Treatment Plant, which works on FAB (Fluidized Aerobic Bioreactor) technology. Even the daily water consumption by the building has been substantially reduced by using low flow fixtures and sensor based taps.
In case of emergency, fire fighting systems and fire alarm systems like fire/smoke detectors with alarms above and below false ceiling, yard hydrants, wet risers, sump and exclusive over head tank, electric fire pump, standby diesel pump and public addressing system with a control room are provided in the building. South Central Railway, Chief Administrative Officer, S K Sharma said, “We are thankful to the Ministry of New and Renewable Energy and ADaRSH for providing their expertise and guidance during construction of the Rail NirmanNilayam project. We will continue our work to enhance energy efficiency. With recognitions like these, organisations do get enthused to reduce energy consumption and conserve the environment.”
ADaRSH is a society established by The Energy and Resources Institute (TERI) with support from and under guidance of the Ministry of New and Renewable Energy, Government of India to implement GRIHA, the national rating system for green buildings.
