This paper reveals daylighting performance with diverse transparency of canopies in the different locations in the UK. Numerical study of using Daysim software for Daylighting measurement is carried out with visual representation and daylight autonomy in the space. This study shows the need for daylighting evaluation in the process of design with different variables (e.g. window area, canopy size or transparency, etc.) so that it may be used to provide optimum daylighting levels for students in different areas. Recent climate changes make schools equip with shading devices, but sometimes it prohibits daylighting from coming to provide visual comfort. Different shading devices are adopted for Daysim software which is most popularly available to calculate Daylight autonomy. The results show electric lighting energy does not show linear match with daylight autonomy (DA) in the classroom due to the glare. Combined daylighting simulation is essential to design canopy and estimate energy consumption as transparency of canopy and orientation of the classroom window plays an important role in controlling the amount of daylight.
