 Following the growing urbanization, choosing and providing housing has become one of the mos t important issues for planners as well as people. Developing a comprehensive program of housing needs complete identification and deep analysis of widespread dimensions of housing and factors affecting them. In the meantime, addressing housing indices, as the key planning tool forming its main thrus t, can be the mos t critical step of planning. By conducting research on identifying and analyzing different housing indicators, the effectiveness of housing programs can be greatly increased. However, among the policies and plans that have been made due to the overcoming of economic factors and the lack of clarification of the good housing index, the qualitative indicators of housing have remained somewhat diminished relative to its quantitative dimension, and planners have more focused on providing housing. This research seeks to find and compare the angles of unders tanding and evaluating the residents' viewpoints on the desired housing, and ultimately, address the impact of location on the mental valuation of residents about the cons tructive components of housing quality. The research method is descriptive-analytical and in order to achieve the desired goals, the qualitative indicators of desirable housing are surveyed from residents' point of view in Shahrak-e-Gharb and Monirieh neighborhoods of Tehran. In the formulation of the questionnaire, 48 items are developed in two areas of the residential unit and residential environment, of which only 13 indicators have a significant difference between the two neighborhoods indicating that the spatial domain has no effect on residents’ valuation of housing quality indices and also the average values given to the items show the great importance of the quality of housing for citizens. 

Microclimate in open space affected by the urban layout and spatial forms plays an important role in the outdoor comfort, thus the outdoor activities based on the comfort sensation will directly affected by the spatial forms. An outstanding open space should satisfy different requirements of outdoor activities and create relatively comfortable place.Most studies have been conducted on these relationships only above 0 Celsius degree. However, only few have focused on extreme situations in both hot summer and cold winter. Therefore, from microclimate perspective, taking people’s comfort and spatial behaviors as criterions, this research discussed how the open space forms affect microclimate, thus affect comfort sensation and spatial behaviors. The outcomes may provide some useful insights for planners and architects to understand the relationship among microclimate, open space and people. Results showed that in hot season, shade and air-flow played crucial roles in outdoor comfort. More people tend to stay outside in the shade and the area with higher air velocity. After sunset is popular period for outdoor activities. The ambient temperature lower than 29.6 ℃ , air velocity higher than 1.1m/s and relative humidity higher than 67% is needed to achieve neutral comfort sensation. In cold season, at the same ambient temperature, lower air velocity raised the comfort level. Shade also had influences on comfort sensation but do not affect spatial behaviors significantly. The ambient temperature higher than -14.4 ℃ , air velocity lower than 1.6m/s is the thresholds for an acceptable outdoor environment.
