12. ENERGY EFFICIENT SOLAR/ GREEN BUILDINGS

13. Perspective for green buildings • In India, energy demand is increasing rapidly, due to increased urbanization and better lifestyle. • Buildings are major consumers of energy, water and generate wastes. • Globally, about 40% of energy consumption and 40% of global emissions is attributed to buildings. • Green Buildings are the answer to reduce the energy consumption & control the pollution • Consume about 40% less electricity and about 50% less water through proper water conservation and waste management practices and solar passive architecture and design

14. GRIHA Rating for Green Building • GRIHA (Green Rating for Integrated Sustainable Habitat), a rating system has been developed which is suitable for all types of buildings in different climatic zones of the country. • It operates on a 100 point marking system and rates the building from 1 to 5 star with 5 star being highest. • MNRE is promoting green buildings construction in the country and supporting GRIHA rating system through some financial incentives.

15. Impact of GRIHA Energy efficient building= Solar passive building + ECBC compliant • ECBC Compliance: • Insulation • High Performance glass • Controls • Efficient electrical , mechanical and lighting systems • Incremental cost: 15% • Payback period < 5 years • Compliance with GRIHA • ECBC + • Passive principles (shading, orientation, controlled glass area) • Higher indoor design conditions (higher by 1 deg C) • Optimized lighting design • No further incremental cost • Payback period: < 4 years 37% 45% kWh/yr

16. Status of GRIHA Rating • ADaRSH an independent registered society created for promotion and implementation of GRIHA. • Government decided that all new buildings of Central Government /PSUs would be GRIHA rated (min. 3 Star). • CPWD has already taken a decision to follow GRIHA ratings in all buildings built by them. • 117 projects registered for GRIHA rating certification with 4.98 million sq. m built up area of which 81 are Government projects with 3.88 million square meter built up area. • Through capacity building over 600 professionals trained of which 115 Trainers and 92 Evaluators are further promoting green buildings/GRIHA rating in the country.

17. IIT KANPUR ENVIRONMENTAL SCIENCES BUILDING GRIHA RATED 60% savings in energy 25% savings in water

18. 5 Star Rated GRIHA Building in IIT Kanpur Trees preserved and protected Solar PV and Solar Thermal systems N-S Orientation with shading (roof/window) Outdoor solar lights Incremental cost 17% Energy savings 52% Payback period :3 years Lesser paving

19. SUZLON ONE-EARTH CAMPUSPUNE, MAHARASHTRA GRIHA RATED 56% savings in energy 50% savings in water 2,50,000 units of electricity generated annually through renewable sources of energy

21. NEED FOR GREEN CAMPUS • Simply making green buildings would not create a green campus it should be sustainable also. • A green campus should follow the optimum path for - land use vis-à-vis population density - Vertical or horizontal growth - Least infrastructure including pitched roads - Transport (more walkability & less use of vehicles) - Renewable energy use and Energy conservation, - Waste management and water conservation • All buildings should be green buildings with GRIHA ratings • Guidelines by July end

22. The Upcoming Campuses • Many new educational campuses i.e, IITs, IIMs, ISERs, NITs, AIIMS, Central Universities etc. are coming up. • IITs and NITs are being built on 600-1000 acres of land. • These may not be sustainable even if they are built with green buildings due to the less population density • These should follow the optimum path of green campuses

23. The NIIT University, Neemrana • Built on 75 acres for 7500 students. • 20 times the density of JNU and 6 times the density of IIT Delhi • Built on fallow land unusable for agriculture • Harvests rainwater by creating check dams and planting trees. • Layout designed to minimize development costs by putting students and teachers housing complexes next to the academic buildings, making the campus: - entirely walk able with pedestrian pathways, reducing the need for motorized transport and minimizing the need for pitched road. • Has a combined system of evaporative cooling and regular air conditioning together with a system of pre-cooling fresh air by passing it through underground tunnel. -

24. The NIIT University, Neemrana • It provides reasonable degree of comfort in the academic buildings at low EPI(energy performance index) of 33 kWh/sq. m/year compared to 140 kWh/sq. m/year for ECBC air conditioning building. • Infrastructure costs of road and services were reduced with compact walk able campus planning.

28. Solar Water Heating Systems Two type of systems namely flat plate and evacuated tube collectors Commercially viable technology Can replace/ supplement geysers & boilers & save precious electricity & fuel oil Helps in peak load shavings besides reducing energy bills & CO2 emissions FPC based system ETC based system

29. Solar Water Heating SystemsCost Economics Capacity : 100 LPD at 80 C, 2 sq. m. solar collector area Installed cost : Rs. 15,000- 18,000 Savings : - Up to 1500 units of electricity/yr depending on use - 140 liters fuel oil /year Pay back : 2- 4 years with MNRE support .

30. Solar Steam system at a Laundry • 240 sq. m. solar dish system installed at Gajraj Cleaners, Ahmed Nagar, Maharashtra for washing & cleaning • System hooked up with existing boiler is generating about 105 kg of steam per hour at 5 kg pressure • saving through furnace oil is around 10,000 liter/yrs • Pay back in 4 yrs with depreciation benefit

31. Battery operated vehicles • Emission free mode of transportation. • Available in a number of seating capacity options. • Can operate up to 80 kms. with one charge. • Cost Rs. 3.5 to 5 lakhs.
