The principle concern of this study is to assess solar absorption coefficient over solar cladding on building and to reduce the high room temperature due to the excess solar radiation over the wall. Simulations were carried out on a college building (kings college of engineering) by using the solar analysis in autodesk Formlt 360, finding a energy efficient wall of an building and solar cladding installation carried out over that area and audit the solar absorption coefficient in the solar cladding. As an results to reduce the room temperature which also decreasing the energy usage by minimizing the usage of fans and leads to a get an sustainable solar energy from solar cladding, by production of renewable energy form solar cladding it reduce the CO2emission which are generated during the production of energy from fossil fuels. © Medwell Journals, 2017.
