Effect of Daylight Application on the Thermal Performa Iraqi Traditional Vernacula Residential Buildings

Abstract

This study includes three stages: the first stage is an analysis, documentation, index through comparison different traditional vernacular buildings (houses) in three cities in Iraqi provinces: Baghdad, Arbil, and the Marshes in Nasiryah province. The study compares data collection through photography and sketches the environmental aspects of the different houses as they respond to the climate, material, construction methods, and passive system. The second stage is an analysis for the daylight strategies of two of the previous regions, Baghdad and Marshes. The study will document all the windows details, and that includes window area, window area compared to the wall area and to the floor area, window treatments and ground and wall reflection. The third stage is analysis for the daylight parameters in Baghdad region only. The study includes visual comfort bench mark: Intensity, distribution, glare, shading, and control (Human intervention/automatic). The analyses documentation of the daylight parameters is going to be through graphic diagrams and sketches. A guideline will be developed based on the analysis and finding from previous sections, and by submitting a model for the analyses purposes. A thorough and professional paper will be delivered to provide proper documentation of the process and it findings.
