abstract
Due to rapid urbanization in developing countries, achieving better outdoor thermal comfort has gained an elevated level of attention, especially within urban settings in hot climates. Although many research studies have focused on improving outdoor thermal comfort in urban settings and many researchers have discussed the influence of a buildings geometry on the availability of daylighting in indoor spaces, there has been very little focus on street design as a means of improving both outdoor thermal comfort and indoor daylighting. This research study examines street design within urban settings in order to find a balanced design that could lead to better day-lit indoor environments and improve pedestrian thermal comfort. A series of quantitative simulations of various street configurations - such as street orientation and the ratio of building height to street width have been performed. In order to find a balanced street configuration that achieves a comfortable outdoor environment and better day-lit indoor environment, the simulation results have been plotted and compared. The results show that the use of overhangs and galleries could achieve the desired balanced result.
