Saurashtra’s commercial capital Rajkot, which was picked up by the United Nations (UN) for its feasibility to implement district cooling system, is all set for a big leap. Its greenfield smart city ‘Raiya’, which was planned under the Centre’s Smart City Mission, will be deploying a district cooling system, which eliminates use of air conditioners and other equipment that emit greenhouse gases. The district cooling system will be implemented in the 930-acres Raiya greenfield smart city.
The recently-published report titled ‘District Energy Initiatives in Cities’ by the UN finds that this unique project has a great potential in cities like Thane, Coimbatore, Pune and Bhopal. That said, once implemented, not a single building in the city will require air conditioning. Chilled water will be distributed in the buildings directly from a pipeline to terminal equipment such as air handling and fan coil units, which will throw cool air even in sizzling summers. District cooling system requires a lot of water. But here, water from stormwater drainages will be treated and used for this considering that Rajkot is a water-scarce city.
The town planning for this smart city will be completed within six months. This will have a central cooling system and no building will require air conditioners. The entire project will cost Rs 1,600 crore and will be implemented on a PPP mode, where an operator will invest and municipal corporation we will also get fees from the system users.
