They appeal to the people in different social status varying from high-incomers to low-incomers from the city center to the peripheries of city. Based on such determination, the satisfaction of house user set forth the main line of work. For this purpose, six parameters have been ascertained to determine the user’s comfort, by interrogating the comfort of interior space in the houses: The thermal comfort, visual comfort, acoustic comfort, humidity and moisture control and design quality.
