Abstract

In Dhaka, most of the time the streets are not designed by anyone. Each owner of the street facing plots built their buildings according to their own requirements. As a result the streets are evolving as a by-product of the buildings. The condition of the urban street is poor. Dhaka does not have any good public transport system. It is one of the least motorized cities in the world and the proportion of all travel by motorized vehicle is low. The DIT (Dhaka Improvement Trust) estimates that 74% of all work trips are on foot or by rickshaw. This figure gives emphasis to the need for the enhancement of the street’s existing environment. In this study the influences in the urban climate are observed for different types of street canyon. The study has used a computer programme called DEROB (Dynamic Energy Responses of Building) for simulation purpose. The simulation period is for the month of April in the city of Dhaka. Comparisons between operative, indoor and outer surface temperature for different types of street canyon are discussed. The study shows that although street canyon geometry have some influence on the indoor climate but it is not significant. However it has great impact on the outer surface temperature of the street adjacent buildings, which can influence the thermal comfort of the street level where people would walk.
