Analyzing of micro climate, environment and solar thermal effect in terms of environmental and thermal comfort in urban spaces(Case study: Analyzing of thermal comfort in shahrdari st in tehran, Tajrish Sq. to Ghods Sq.)

Respect of the natural and environmental climates has become one of the main issues associated with technological sciences, particularly with urbanism and architecture.   Thermal comfort, the reduction of energy consumption, the control of energy exchange between human and his natural and artificial environments are all important factors in urban design. Moreover, pedestrian instead of vehicular area are given preeminence. In urban design and planning, in order to optimize the comfort of pedestrians, various climate related factors must be taken into consideration. In the present research we ask two questions; first which climate factors influence positively the environment and secondly in order to create an urban space in symbiosis with the microclimate, what should be done? Factors influential on the thermal comfort are introduced using the Ecotect software (an analytical software of various climate and energy related factors). First the data for the climate of Tehran are analyzed, and then the important factors influencing the environmental comfort of its microclimate are evaluated. Sunlight exposure, wind, relative humidity, relative shadowing, thermal comfort and other environmental factors are studied in parallel with building location. The various problematic emplacements are identified and solutions are proposed. The main goal of the present research is to clearly identify the most influential climatic factors in urban environment and use them in urban design, particularly for the design of pedestrian areas.
