To allow natural light into house most of them prefer Daylighting. In daylighting practice the windows, openings skylights etc are provided to have efficient internal lightining. While designing a building Daylighting should be given special attention as use of natural light will reduce the consumption of the artificial light.
Natural light is also dependent on the climatic condtions of the region, some times the light reaches directly into house or sometimes its scattered. it also depends on the site location also. Usually in case of northen hemispere the noth facing walls will not have diect sunlight and same with the south facing walls in the southern hemispere.
in this case during the design of building fo natural lghtining into house, opening or windows provided are less and of smaller size in noth facing walls of northen hemisphere and south facing walls of south hemisphere. But larger openings and lager window are provided for south facing walls of northen hemisphere and north facing facing walls of southren hemispere.
different types of lightining provides into house are use of glass to windows, swatooth roof,atrium, transluent walls, light tubes, light reflectons and shelves etc.
jus apart from visuality and light into the building, there are other advantageous factors of proper day light in the building or any industrial areas such as productivity, work satisfaction etc than under electrical lightning.
