The economic development of a country is closely linked to its energy consumption. Currently, India is ranked 6th in total energy consumption it still needs more energy to keep the pace in control with its future development. At present changes have made to make building more energy efficient keeping the usage of buildings energy consumption in mind The main objective of this thesis is to obtain a clear understanding of the usage of building energy consumption and To study the economic benefits and advantages of an NZE office building in hot and Humid climate and reduce the carbon footprint in future where the energy demands are increasing day by day and to achieve it in a low cost. It is done through evaluating the building performance and energy usage (EUI) by modeling and stimulation by analyzing energy use index, various optimistic design solutions,s and life cycle cost. The study also deals with finding solutions that reflect current trends achieved towards making building more intelligent, self-sustained, and more sustainable.
