Punjab Energy Department Agency Bhawan is an official building of non conventional renewable energy society focused on innovation, development, promotion, facilitation, conservation and implementation of projects/ programmes in the realm of exploiting renewable energy resources like solar energy in the state of Punjab. 

It was setup in Sept 1991 in Sector 33, Chandigarh, Punjab with a covered area of 70, 000 sq feet spread over 1.5 acres. Prof. Dr Arvind Krishan, the architect had achieved a three dimensional design solution in response to the challenge of composite and conflicting climatic conditions. It is a passive solar defined structure that employs sun’s energy and its trajectory to run the lightening, heating and ventilation system. The strategies adopted by PEDA contributing towards low environmental impact with efficient utilization of conventional and non-conventional energy are reflected in the building’s architectural configuration. It was rated five stars by the Bureau of Energy Efficiency.

Following are the solar envelop complex features of PEDA projecting clean green vision:

  • Orientation: The orientation of the building is such that it brings in light from south west during winters and cuts it out during summers. Thus enveloped to enact favorably in response to climatic swings.
  •   Solar Power Plant: 25KW building integrated solar photovoltaic power plant has been set up to meet the basic requirement of electricity in the complex.
  • Unique Shell Roofing: The complex is constructed with hyperbolic shell roof to admit daylight without glare.
  • Insulated Roofing: All the roofs have been insulated with double insulation system to avoid penetration of heat from the roof.
  • Cavity Walls: The complex is made up of its outer walls 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.
  • Water Bodies: Waterfalls and fountains have been placed in the central atrium of the complex for cooling in the hot and dry period.
  • Unique Floating Slab System: Allows 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.

      The former PEDA director S. S Sekhon has stated in Tribune News Services, that PEDA building was low energy architecture building making optimal utilization of wind and solar energy, which would help to save at least 40-50 % in electricity bills. The agency had installed solar power projects at Parliament House Complex, Golden temple Complex (Amritsar), Durgiana temple (Amritsar), Punjab Agriculture University (Ludhiana), the Punjab Raj Bhawan (governor’s house), Rashtrapati Bhawan and is targeted to cover innumerable small towns/ villages in Punjab.
