implementing of sustainable energy programmes across the state. GEDA’s challenge has been to make the renewable energy and energy efficient technologies economically and commercially viable. GEDA was catalytic in the formation of the Commission of Additional Sources of Energy (CASE) in 1981, which later became the Department of Non-conventional Energy Sources (DNES) in 1982 and a full-fledged Ministry- MNES (Ministry of Nonconventional Energy Sources) in 90s, GEDA has played a pioneering role which is now the MNRE (Ministry of in the development of a long-term New and Renewable Energy).

G u j a ra t E n e r g y D e v e l o p m e n t Agency (GEDA), one of the premier organizations in India working in the field of renewable energy development and energy conservation is shouldering the
responsibility as the state nodal agency (SNA) for the Ministry of New and Renewable Energy Sources (MNRE) and the state designated agency (SDA) for Bureau of Energy Efficiency (BEE). It has played a pioneering role in the development of a long-term policy and implementing of programmes across the state. Gujarat: Empowering a “Renewable” Future GEDA was instrumental in introducing various technologies for mass use through design of several innovative programmes, i nvo l ve m e n t o f r e p u t e d N G O n e t wo r k a n d i m p l e m e n t a t i o n strategies and promotional initiatives. A key link in GEDA’s initiatives was the establishment of a network of reputed NGOs for grass root penetration and the development of a manufacturing base. The renewable energy technologies that have already been proven are: 1. Bio, solar and wind resources as additional resources for power generation to supplement the grid. 2. Electrification of remote and far flung areas where conventional energy cannot be made available because of various constraints. 3. Solar and bio resources for p r o ce s s h e a t a p p l i ca t i o n s , heating and cooking.
4. Bio, Solar and wind resources for water pumping. 5. Cleaner non-polluting fuels for transport. 6. Energy efficient practices, and devices, and efficient building designs. 7. The proactive Government of Gujarat has been and is already driving on the sustainable path way. Power generation projects / programmes from wind, solar photovoltaic and biomass have successfully demonstrated that renewables are here to deliver grid-quality power. Experiments in decentralized energy supply models especially for solar cooking, solar water heating systems in the domestic and industrial sectors and decentralized power generation projects are successful case studies that can be replicated from small to large -scale levels.

Gujarat: Wind Energy, the Big Player On the wind energy front the state h a s a l s o e m b a r ke d u p o n a n ambitious plan to tap the large wind power potential. In 2009, the Government of Gujarat announced an amendment in the Wind Energy Policy to tap the 10,000 MWe of the Wind Power potential along the coastal areas – Saurashtra and Kachchh. Today, this policy has undergone major revisions to attract even more investors in the field.
Today, Gujarat has already installed 3114.25 MWe of Wind Power Projects which is already catering to 7.6 % of the annual energy consumption of the State at an investment of Rs. 9500 crore. These Projects annually generate 3800 million units of electricity, saving 2.60 MT coal and reducing the carbon emissions levels by 3.80 million tonnes

The sequential frames at every floor along the path to the water portray the image of Lord Vishnu under the hood of Sheshnaga (the serpent god) as a consistent visual focus and a reminder of a journey of the Patal Lok (the nether world).

Th i s construction methodology develops its own language in terms of its spatial organization. Here the only visible clue above the ground is the pair of large pilasters flanking a wide flight of steps. They become the inviting portal to climb the steps leading to a platform. Although there is a straight linear sy mmetrical organization of elements along the horizontal axis, the visual references continuously change due to inclined movement at every step. While the sight lines extend through the entire length of the well, the visual frame constantly changes with the changing eye

The following are the strategies through which passive cooling techniques were applied: 1. Appropriate Orientation 2. Shading devices 3. Thermal Mass (Time Lag)
Climatic analysis along with thermal co m f o r t co n d i t i o n i n g h e l p e d explore the appropriate passive strategies that could be incorporated in the building to provide comfort and reduce the energy consumption at the design Three passive strategies: night stage. ventilation, comfort ventilation and evaporative cooling are considered
Campus Planning throughout CEPT
Psychometric studies were done with emphasis on the occupied hours outside comfort range which provided means to identify passive strategies and to evaluate the limits to which they would be able to provide comfort. Some applicable passive strategies that were explored and experimented with were building shading, natural ventilation and thermal mass. The building envelope is designed such that the building operates in natural ventilation, temporal mixed mode and air-conditioned mode. Th i s w a s m a d e t o d o w n s i z e mechanical cooling demand and electric lighting. Walls and roof have external insulation and higher internal thermal mass. In order to improve the building envelope, exterior insulation was an important strategy. By providing an additional brick layer on the external surface of the insulation it had the added advantage of increasing the thermal mass of the NZEB and helped operate the building in mixed mode along with night time ventilation. We will be able to see the following passive design strategies for cooling the buildings: 1.
