Signifcant contradiction arises in buildings in the hot climate regions when relating window sizes and shadings to achieve both reduced energy consumption (requiring minimum opening ratios and more shading) and suficient daylighting (requiring maximum opening ratios and less shading). This paper is a part of an on-going Master Thesis research based on a Parametric Analysis to study the quantitative effect of window’s ratio, glazing and shading techniques on Daylight Autonomy and Energy Consumption in a hot climate region. This study aims to aggregate two different parameters to achieve better daylight autonomy and less energy consumption, mentioning possible further criteria for assessing the buildings performance.
