The study of the role of two-shelled facades in residential buildings in Guilan

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.

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
