The present building rules would be changed to make use of solar energy compulsory in buildings to reduce dependence on conventional energy, Tripura Science, Technology and Environment Minister Joy Gobinda Debroy said.
"The rules would be applicable to private, government and commercial buildings," Debroy said.
With the Centre suggesting that Northeastern state capitals should be included among 60 cities in the country to be turned into solar energy hotspots, Debroy said the state government had started preparing a detailed project report.
A survey would be undertaken in Agartala soon, he said.
