Andhra Pradesh will use innovative ‘Indo-Swiss energy efficient building technology’ in its housing scheme under which it proposes to provide housing for all. Under the initiative, 30 lakh affordable houses would be constructed in the state. By adopting this new technology, the government hopes to reduce the temperature by about two degrees inside houses and save about 20 per cent electricity.
Indo-Swiss Building Energy Efficiency Project (BEEP) is a bilateral cooperation project between the Ministry of Power, Government of India, and the Federal Department of Foreign Affairs (FDFA) of the Swiss Confederation. Started in 2011, the project’s central focus is to help India mainstream Energy-Efficient and Thermally Comfortable (EETC) Building Design for both commercial and residential buildings. BEEP works with building industry, policy makers, and building owners to catalyse adoption of EETC building design and technologies. The Bureau of Energy Efficiency is BEEP’s implementing agency for the Ministry of Power, while the Swiss Agency for Development and Cooperation oversees the project for FDFA.
Under the new technology, the rate of heat transfer to the roof would be reduced by using roof insulation or reflective paint on the rooftop. The autoclave aerated concrete blocks, cavity wall, hollow bricks, etc. will reduce the net heat gain over building envelope. Using proper window shading like blinds or rolls kept outside the windows will also lower net heat gain.
Under the ‘Building Energy Efficiency Project’, the Bureau of Energy Efficiency (BEE) through Indo-Swiss BEEP will provide training to engineers and employees of ward and village secretariats and the housing department. This would help in effective implementation of Energy Conservation Building Code-Residential (ECBC-R) in this affordable housing programme. Initially, 50 engineers will be trained as master trainers who can impart the training by themselves to other engineers.
