Design of Balcony from the Point of View of Daylighting

Abstract:

Balconies are horizontal overhanging structures whose main function is a connection between interior and exterior space. Moreover, they increase an area of a room and they also can have a presentable, architectural and aesthetic purpose. There are a lot of requirements on the balconies, for example the requirements on static properties, thermal bridges, railings or fire safety. From the point of view of building physics, we can consider the balcony as the fixed shading construction which can reduce overheating in a shaded room during the summer but on the other hand the balcony can influence visual comfort in the room in a negative way. This article presents a comparison and an evaluation of the daylight factor in the rooms which are shaded by balconies. The influence of the balconies on the daylight factor is assessed in dependence on a length of the balcony (a balcony overhang) and dimensions of the room which the balcony shades.
