Indira paryavaran bhawan and griha
The document describes the Indira Paryavaran Bhawan building project in New Delhi, which aims to be a net zero energy green building. Some key points: - The building has a 930kWp solar PV system, the largest rooftop system on a multi-story building in India, which meets the building's total energy demand. - Energy efficiency measures like chilled beams, geothermal heat exchange via 180 deep boreholes, and high performance glass optimize energy performance and reduce cooling loads. - Sustainable materials like fly ash concrete, AAC blocks, and jute-bamboo composites are used to reduce embodied energy. - Water conservation strategies like rainwater harvesting and
