A Review on Net Zero Energy Building

Abstract

Commercial and residential buildings consume about 33% of the total electricity used in the country. Due to the urbanization, the movement of people from rural parts of urban areas has led to increased energy consumption, especially in the commercial sector. The commercial building sector is expanding at a rate of 9% per year. The residential sector consumes 24% of electricity consumption in India. This increasing energy demand makes it important to add new power generation capacity along with the options to reduce the energy demands of various end-users. To bring this change, a policy for improving energy efficiency in both new, as well as existing buildings of both sectors, is required. All over the world, there are many initiatives taken to improve the energy performance of buildings with the names such as net zero energy or zero net energy. The continuous stress on the environment has resulted in a major focus on Net Zero Energy Buildings and high-performance buildings. In such a scenario of a shortage of raw materials and devastating climate changes, the greening of the building plays a vital role. Due to various difficulties in having energy through renewable, the conservation through green buildings cannot be ignored.
