Living in tin or asbestos roofed structures or the usage of tarpaulins, they need to face tough conditions.
Considering all these elements, experts and researchers at the moment are pitching for what they call the ‘Cool Roof programme’. Cool roofs replicate sunlight, absorb much less heat and provide a value-powerful solution for the demanding situations of urbanization and help in protective the surroundings. They store power, increase thermal consolation and decrease cooling call for inside the longer run.
Telangana is in the vanguard in beginning measures for enforcing the ‘Cool Roof programme’. The Municipal Administration and Urban Development (MAUD) and Greater Hyderabad Municipal Corporation (GHMC) took up a pilot venture in 2016 and 2017. The Telangana Cool Roofs programme is a goal-primarily based initiative to increase the share of cool roofs within the State.
Under three categories for different constructing sorts, the initiative is taken up placing every year targets. The Telangana Government has already initiated steps involving Administrative Staff College of India, Greater Hyderabad Municipal Corporation, Natural Resources Defense Council, International Institute for Information Technology, Hyderabad and Telangana State Renewable Energy Development Corporation. A draft copy of the programme has also been prepared for dialogue.
Initially, the MAUD will formally undertake the “Cool State Programme” as a policy measure for the State. In the longer run, to make sure adoption of cool roofs by means of municipal homes, MAUD may want to make it mandatory in all new structures and retrofit the prevailing government homes and comprise cool roofs when they’re undergoing maintenance. In case, a building is not due for renovation inside three years, MAUD could do not forget imposing cool roofs quicker as a part of the larger effort.
