Abstract
Orientation of classrooms is an important challenge in architectural design of a school. However, there is a lack of appropriate knowledge about influence of orientation on students’ perception of daylighting in classrooms. This paper presents a questionnaire survey that was conducted to compare students’ perception and satisfaction with daylighting in classrooms of a high school in Tabriz, Iran. Statistical analysis of responses was done to identify daylight factor and their relationships with satisfaction with daylighting in northern and southern classrooms. In southern classrooms, satisfaction with daylighting had significantly negative and positive correlation with perception of reflected and direct glare, respectively. In northern classrooms, perception of unified daylight and control of sunlight overheating by operable windows had significantly strong and positive correlation with satisfaction with daylighting, respectively. The students’ seating location had significant influence on satisfaction with daylighting and perception of direct glare in southern classrooms. In northern classrooms, students’ seating location caused different perception of reflected glare. The results showed that orientation did not lead to significant difference between satisfactions with daylighting in northern and southern classrooms. Although, in southern classrooms, the mean votes of satisfaction with daylighting was higher than northern classrooms.

Abstract
Nowadays, due to rapid urbanization, People can’t participate in outdoor activities. On the other hand, environmental issues such as climate change and heat stress have caused thermal dissatisfaction for users. In this regard, studying outdoor environments becomes crucial. In the present historical context, lack of responsive urban layout consequences not only morphological problems but also causes thermal dissatisfaction during the passages. The present study aims to find the responsive layout pattern for providing an approximate outdoor thermal comfort based on local criteria and limitations in summer and winter; which requires the minimum intervention in the current context. In this regard, we intend to represent three basic street patterns (Linear, Grid, and Circular) as alternative designs and attempt to localize them with the current urban layout. For analyzing the prototypes, we used Envi-met Beta software to compare the average amount of climatic factors, orientation, and H/W ratio for the alternatives. In addition, the PMV factor (=Predicted Mean Vote Model) was used as a measurement index of outdoor thermal comfort. According to the outcomes, the Radial pattern with dominant NE-SW oriented passages prepares adequate solar energy in the winter. Also, it could balance the high radiation during the summer, whereby provides optimal thermal satisfaction in both hot and cold seasons.
