murari sir 2The rapid urbanization needs more and more energy efficient buildings. In the past 15 years quite some advances and multi-pronged approach involving adoption of bio climatic architectural principles have taken roots in the country. This concept have changed the intigated approach to building design. If the techniques and the approach for energy efficient buildings are applied to just 10 percent of the buildings constructed in cities every year, we can save to light 20 million rural households. According to the estimate by year 2030, the Indian building stock is expected to reach 100 billion square feet compared to the existing 25 billion square feet. India has over 2380 registered green building projects. In brief, an energy efficient building balances all aspects of energy use in a building viz. lighting, space-conditioning and ventilation by providing an optimized mix of passive solar design strategies, energy-efficient equipment and renewable sources of energy. These buildings use the technique and procedures viz. a combination of modern science and traditional knowledge. Basically the main important factors are to save energy and harnessing modern science. The solar water heaters are now a common sight on the rooftops and saves energy for heating water. Integrated photovoltaic systems produce electricity and is fed into a battery bank, which is the main source of light at night. Some of the top green buildings in the country are of corporate and institutional buildings. For example CII- Sohrabji Godrej Green Business Centre, Hyderabad is one of the world’s best example of passive architectural design and with roof garden as well as solar photovoltaic, system thereby reducing the energy consumption by almost 60 per cent than that of conventional building. The CRISIL House at Hiranandani Gardens, Mumbai is one of the greenest commercial complex in India. Infosys Limited at Mysore where the building design is of efficient equipment and automation is used. ITC Green Centre, Gurgaon and ITC Hotels all over India are premium luxury hotels LEED (Leadership in Energy and Environmental Design) Platinum Certified. The building complexes constructed to save energy are Infinity Benchmark, Salt Lake City, Kolkata, Suzlon One Earth, Pune, Patni(i-Gate) Knowledge Centre, Noida, Great Lakes Institute of Management Chennai. These buildings often are not cost effective to construct but in the long run saves considerable energy costs.
