The building sector currently accounts for about one-third of the total worldwide energy use and much of this consumption is directly attributed to building design and construction. The World Green Building Council defines Net Zero Energy Buildings (NZEB) as buildings that are highly energy-efficient and fully powered from on-site or off-site renewable energy sources. The purpose of this article, is the effect of Zero-energy buildings to improve the sustainability and energy efficiency. The energy needs for ‘Net-zero energy’ buildings are met through non-conventional energy systems such as solar arrays, wind turbines, biomass, or other renewable resources. These buildings are characterized by net-zero consumption of energy and zero carbon emissions, making them self-sufficient. Furthermore, zero-energy buildings generally have a variety of nonenergy benefits relative to standard buildings, such as improved comfort, improved occupant health and productivity, more room for living and working because less space is needed for heating and cooling systems. Reducing emissions from buildings continues to be one of the most cost-effective solutions to tackling climate change. Finally, Zero-energy buildings will deliver economic growth, create jobs and improve energy security.
