Traditional HVAC systems has low efficiency and high pollution and so life on the earth is confronted to the greatest challenge after beginning of civilation. In recent decades, however, sustainable policies and plannings are offered many amendatory ways to change building design process as integrated design process and holistic approach which was profited to rise energy efficiency in equipment. Net zero energy building is a result of common aim and responcible participation of architects, civil and electrical and mechanical engineers in this area. This type of buildings has greatly reduced energy needs through efficiency gains such that the balance of energy needs can supply with renewable technologies. This article was conducted to present this process design to determine intervener factors and the rate of success ultimately. Research method is on descriptional- analytical due to study library's documents and review case studies. One of the major pollutant in the nature is greenhouse emisions caused by fossil fuels.
