Measurements and Analysis of Day Lighting Conditions in the Iranian Traditional House: Case Study in Kerman

Natural light has a great effect on the health of humans. Providing natural light in living spaces is the best way to promote a healthy life. In Iranian traditional architecture, especially in residential building using natural light for lighting is very important. Based on research conducted on Iranian traditional house's, is determined that they have many aspects in daylighting design. The aim of this research is to investigate deferent lighting methods to compare traditional design methodologies of the Iranian traditional building. In this paper, is tried to investigate a survey of observation, geometric assessment of devices and the results of measurements of daylight levels of rooms that selected in a traditional home in Kerman. The selected samples include 3 rooms, one of them with skylight roof (kolah Farangy) the others are rooms with door-windows into the yard (Seh Dari and Panj Dari). Also, the monitored results of models were analyzed results of, under the sunny and clear sky. The illumination was measured in this experiment by using light meter in selected rooms. In addition, some simulations were carried out in the selected samples by the means of simulation software "ECOTECT v 5.6". Finally, the problems were determined and comparison of both results was discussed. Then the results have been analyzed.
