The north Indian city of Chandigarh should become a solar city. The first step in this direction is a building byelaw which was published in October 2008 and came into effect on the 21st December 2008.
“The issue was under consideration for a long time and had to be implemented”, says Sanjay Kumar, the chief administrator of the Union Territory of Chandigarh. The following is written in the byelaw: “All commercial, institutional and hotel buildings which have use of hot water shall have solar water heating systems of adequate capacity installed. The existing buildings which do not have those facilities shall provide this facility within one year from the date these orders are notified in the official gazette.” This is a very far-reaching rule without any exceptions.
The byelaw allows residential building owners a transitional period of two years. “We have given residential buildings a timeframe of two years, keeping in mind that senior citizens live alone in some of these houses”, explains Kumar. “Such people might not be that swift in implementing the provisions. The timeframe will ensure that, after time, all houses are going to possess such systems.” Further information see table below.
The byelaw stipulates the construction of 100 litre solar water heaters in residential houses constructed on a parcel of 506 m2 (1 kanal house) and a solar water heater with 200 litres for residential buildings constructed on a parcel of 1,012 m2 (2 kanal house).
