Abstract
Abstract -: Buildings are a major primary energy consumer in the world energy sector, with a value of about 40% of total energy consumption. The absence of traditional sources of energy currently promotes the development of Net Zero Energy Buildings (NZEBs). The general definition of net zero energy construction is very critical to grasp. The aim of the paper is to overview the literature on the existing NZEB to make them self-sustaining and net zero in order to improve energy efficiency of the buildings. If enough renewable energy could be used, NZEB could potentially be achievable with power production. Furthermore, different building-service systems utilizing renewable energy sources have been extensively investigated for possible uses in NZEB. The paper gives the detail of its climatic condition in various part of the world along with their consequences and its impacts. The NZEB concept will significantly define the demand and supply strategies for renewable energies and conversion accounting to achieve a NZEB target along with its renewable energy evaluation. Buildings account for a large proportion of the world's total energy and carbon emissions, and play an important role in formulating strategies for sustainable growth. To this end, smart systems implement applications with numerous and interdisciplinary features. Here, the paper gives a detailed literature review on NZEB.
