Abstract: With a value of around 40% of overall energy consumption, buildings are a significant main energy user in the global energy sector. Currently, the absence of conventional energy sources encourages the construction of net zero energy buildings (NZEBs). Net or nearly zero energy buildings (NZEB) are exceptionally energy-efficient structures with very little demand for energy, all of which are supplied by renewable resources. Such structures annually balance their energy use and production. It's crucial to understand the broad notion of net zero energy construction. The paper's objective is to present and discuss various strategies and ideas to achieve Net Zero Building through actual Modeling. Designing and Optimization of Building
