The concern for energy savings is increasing in the world. Buildings have great potential for energy savings, and in this scene, the European Union1 is trying toregulate the rules of its member states. In 2010, a new direc1ve was published, which will help reduce EU buildings energy consumption in the long run. Arequirement that all new buildings must be net zero energy consumers by 2020 has received the most attention. Based on the energy balance sheet, annuallymore than 40% of energy consump1on is directly used to serve the needs of building sector in Iran. Most of the studies in this area show that more than halfof this energy goes to waste for different reasons. The main aim of this paper is to offer techniques to approach Net Zero Energy Buildings2 in Iran. Thus, through energy auditing of the office building of Electric Power Distribution Management in Malekan city, this facility was considered for its energy consumption and different techniques for energy consumption optimization were evaluated technically and economically and the best of them were proposed. Also the possibility of using renewable energies to serve energy needs of this building has studied.
