Zero Energy Building

Abstract

A zero net energy building (ZEB) is a commercial or residential building with much lower needs through energy obtained such that the balance of energy needs can be contributed with renewable technologies. It is reported that 30 to 40% of the primary energy used worldwide in buildings. The use of high energy may affect the environment directly or indirectly also it originates climatic change degrading the environment and expand the air pollution. Hence it’s important to make smaller energy use in building great environmentally sustainable. To overcome this problem zero energy building concept is developed. In this paper we have to study and analyse the performance of zero energy building and also give an overview on an existing building to make it a proper net zero energy building.
