  7. Abstract:
  8. This study is a modeling for “building’s energy consumption” as well as selecting an optimum composition of technologies to meet a building’s needs, with an approach of reducing energy and facility costs . In modeling the energy stream to evaluate heating comfort and to calculate building’s heating load, the interaction between these two phenomena is assumed to be en block. The unique and en block study requires surveying mass and energy streams from all particles of a building, which are not traceable in simple static methods. This study assumes a building with following requests: heating load, cooling load,air conditioning and heat water. An optimum selection of facilities and appropriate width of insulator are other outcomes of the proposed model. The interactions among particles here, are assumed through an sketch of building’s energy balance sheet and the national rules. The model is proposed under “the law of conservation of mass and energy” and is solved via non-linear mathematical programming, hence the optimum capacity for cooling , heating and air conditioning facilities and the optimum width of insulator to reduce lost are calculated. At the next step , in three stages in regards with the rise in energy carriers price, the sensibility analysis on the given results was employed
