Solar Passive Complex

Large Projects - Solar Passive Complex

Chandigarh the modern and planned city designed by Le-Corbusier, lies in the plains at the foot of the Lower Himalayas, is the capital of Punjab and Haryana.

Punjab Energy Development Agency (PEDA), Chandigarh is a state nodal agency responsible for development of new & renewable energy and non-conventional energy in the state of Punjab.

PEDA – Solar Passive Complex, Chandigarh is a unique and successful model of Energy Efficient Solar Builidng, designed on solar passive architecture with the partial financial support of Ministry of New & Renewable Energy, GOI and Deptt. of Science, Technology, Environment and Non-conventional Energy, Govt. of Punjab. It is setup at Plot No. 1 & 2, Sector 33-D, Chandigarh on a plot size 1.49 acre (268ft. x 243 ft.) allotted by Chandigarh Administraiton, U.T., Chandigarh with a total covered area 68,224 Sq.Ft. including 23,200 Sq.Ft. basement. It is the centre of Excellence for Solar Buildings, minimizing conventional lighting load in the office building, efficient movement of natural air, light vaults, wind tower coupled with solar chimney, BIPV, Water bodies, designed landscape horticulture and energy conservation activities.

Salient design features of Solar Passive Complex.

PEDA – Solar Passive Complex heralds the beginning of the energy efficiency movement in the non-domestic buildings such as offices, educational institutions and factories. The building has the following salient design features:

Orientation: Solar Passive Complex has been developed In response to solar geometry i.e. minimizing solar heat gain in cold period. The building envelope attenuates the outside ambient conditions and the large volume of air is naturally conditioned by controlling solar access in response to the climatic swings

Solar Power Plant: 25Kwp building integrated solar photovoltaic power plant has been set up to meet the basic requirement of electricity in the complex

Unique Shell Roofing on Central Atrium : The Central atrium of the complex having main entrance, reception, water bodies, cafeteria and sitting place for visitors constructed with hyperbolic shell roof to admit daylight without glare and heat coupled with defused lighting through glass to glass solar panels. The roof is supported with very light weight space frame structure.

Water Bodies: The water bodies with waterfalls and fountains have been placed in the central atrium of the complex for cooling of whole the complex in the hot and dry period.

Light Vaults: The vertical cutouts in the floating slabs are integrated with light vaults and solar activated naturally ventilating, domical structures in the south to admit day light without glare and heat.

Cavity Walls : The complex is a single envelope made up of its outerwalls as double skin walls having 2" cavity in between. The cavity walls facing south and west are filled with further insulation material for efficient thermal effect.

Unique Floating Slab System: The system of floating and overlapping slab with interpenetrating vertical cutouts allow free and quick movement of natural air reducing any suffocating effect.

Landscape Horticulture : The space around the building inside and outside of boundary wall and a big lawn in the south has been designed with trees, shrubs and grass. The big trees along the boundary wall acts as a curtain to minimize air pollution, sound pollution and filter/cool the entry of air.

Wind Tower coupled with Solar Chimneys : The wind tower centrally placed coupled with solar chimeys on the domical structures for scientific direct & indirect cooling and scientific drafting of used air.

Insulated Roofing : All the roofs have been insulated with double insulation system to avoid penetration of heat from the roof. Auditorium:A unique auditorium scientifically designed to control heat penetration, light & sound distribution is placed in the north under the shade of main building.

Big Exhibition Centre : The complex is having a proper designed exhibition centre for display of renewable & non-conventional energy devices / equipments.

Unique Workstations : Scientifically designed and fully equipped unique workstations have been made for the employees having comfortable environment, good ergonomics with sufficient natural light and air.
