Abstract:
Today, tall building is a phenomenon that the world particularly large cities are facing. The tall buildings in
order to exploit the land with having the negative affects in the environment create new problems including
increasing congestion population, environmental pollution, reduce citizen access to fresh air and sunlight.
However, regarding to population increasing and land shortage, tall buildings could not be avoided. This paper
investigates the relationship of tall buildings with urban air pollution as well as the possible reducing of
negative affects of tall building on environmental pollution with respect to geographical position, technical
rules, immunization, green space, direct of wind, appropriate distance to other buildings, design in terms of
visibility and landscape and urban appearance were reviewed. The study showed that the tall buildings cause
increasing the air pollution in large urban area due to changing in wind and its direction and also congestion of
tall buildings as a pollution sources. Therefore some techniques to design the tall building must be considered
to reduce the negative affects of the tall buildings on environmental pollution. Unfortunately the lack of the
construction roles in term of environmental protection and also control of the rules in construction process
causing the environmental pollution particularly air pollution. It is suggested that the re-evaluate of the rules
with restricted control can improve the air quality in the large cities and also utilization of green spaces in
floors and roofs of buildings as environmentally friendly buildings which are attempt to reduce environmental
problems.
