impact of airflow on moderating thermal conditions in vernacular houses; case study: bandar-e lengeh houses in hot and humid climate of iran

As an example of extreme hot humid climate, the southern marginal rim of iran is a perfectcandidate for studying climatic patterns. attention to climatic components in housing design processwithin this area is therefore essential. benefitting from the airflow and avoiding heat and radiationare among the most effective approaches towards moderating heat conditions in hot and humid areas.vernacular houses are principally built to adapt to the climatic needs. bandare lengeh in southern rimof iran has vernacular houses with unique patterns to make use of the airflow. with the aid of the designbuilder software application, this article examines heat conditions in such houses in accordance withlocal wind patterns and airflow in the climatic structure of the houses. it also tries to investigate theextent to wich such airflow effective can be effective in moderating indoor heat conditions of the climaticconditions in bandare lengeh houses. the article has a practical purpose, which is being followed throughapplication of graphical and simulation packages using design builder software version 4.2.0.045 andthe ashrae55 thermal comfort model. the climate statistics data are prepared by meteorem 7 software,using weather data from meteorological organization of iran. conformance of the obtained simulationresults show that local windflow currents in bandare lengeh combined with unique climatic patterns ofthe local houses can help moderation of indoor thermal conditions and provide the best ambient status,regarding air currents temperature and relative humidity in certain hours of the day.
