Investigation of Solar Passive concepts in building envelope for a reduction of energy usage

Efficient utilization of renewable energy by reducing the dependency on conventional energy sources has become the major concern currently in the field of engineering and scientific research in order to mitigate the environmental issues caused by the conventional sources. There are many researches happening worldwide for reducing building energy consumption by introducing passive concepts. The present work reviews such passive solar concepts and its integration in building envelope design to provide thermal, lighting and acoustic comfort for occupants residing in the building without the help of any conventional space heating and cooling techniques.
