In a time when most of the Earth's fossil energy resources are decreasing and the population continue to increase, human needs to control his residential space weather in comfort range without any waste or excessive consumption of energy. Nowadays various technologies are used to create comfort, security, and saving in costs particularly in energy consumption. Two-shelled facade is also one of the measures that with the advancement of knowledge and development of science in recent decades, has made it possible for construction industry to be compatible with the environment so that it can help to adjust heat, cold, light, wind, as well as outside noise and provide residents' welfare without wasting energy. The application of this technology is necessary in modern buildings of Guilan according to the extent of the area in the country that can reduce a large part of fossil energy consumption by creating natural ventilation and draft that it's important factor of comfort is the reduction of excessive moisture in the area that is hard to bear for man. Therefore, the aim of this article is to study of the two-shelled facades and the amount of influence of this technology on reduction of fossil energy consumption and man's comfort in the building. The descriptive-analytic research method has been used in this research based on data collection by library method. The results of this study indicate that in addition to possibility of natural ventilation while controlling noise, wind, and rain, two-shelled facades case to human comfort in building with reduction of costs and creating a desired landscape
