This document discusses sustainable built environments and GRIHA (Green Rating for Integrated Habitat Assessment), India's green building rating system. It covers the following key points: - Elements of sustainable habitats include optimal land use, transportation systems, water and waste management, and use of renewable energy sources. - GRIHA was created to facilitate the design, construction and operation of green buildings in India and to measure their environmental performance. - GRIHA criteria cover areas like site selection, energy and water efficiency, waste management, and indoor environmental quality. Projects are rated on a 100-point scale to determine their level of sustainability. - There are different GRIHA variants for buildings of different sizes

Can you design a green building? 1.By adopting the integrated design approach such that the client, architect, engineers, and consultants design the building in a coordinated manner with a common goal – sustainability. 2.By following regional development plans (such as the UDPFI guidelines, master plans) and local building by-laws 3.By following India’s national codes and standards 4.By optimizing site conditions (trees, water bodies, wind-flow, orientation, etc.) and harnessing them to cater to the thermal / visual comfort requirements of the building 5.By adopting sound architectural practices and taking examples from India’s traditional architecture 6.By adopting locally available construction materials and giving impetus to local arts, crafts, architecture and artisans 7.By designing precisely-sized energy systems and not basing them on broad thumb-rules 8.By reducing the resource consumption of the building and its inhabitants so that the waste generating there-from is reduced 9.By adopting energy efficient technologies (EETs) and equipment 10.By adopting renewable energy technology (RETs) applications to reduce the demand on conventional energy

Editor's Notes

  1. India’s coal resources have been downgraded to provide secure access for just about 40 years India is suffering from huge estimated shortages of nearly 10% in energy terms and almost 17% in terms of peak demand The number of cities with population of 1 million and above has increased from 35 in 2001 to 50 in 2011, and this number is likely to increase further to 87 by the year 2031 (Report on Indian Urban Infrastructure and Services, March 2011)
  2. From the literature
  3. Energy cycle ZERO/NO Cost (design) – reduce demand Further reduction by efficient systems Lowered demand to be met by clean energy
  4. Over 425 registered projects across India with More than 12.5 mn sqm of built-up Over 35 registered pilot projects under SVAGRIHA 2 pilot projects registered under Large Development Guidelines
