NEW COMPONENT FOR DAYLIGHTING - FIRST ITALIAN APPLICATION OF A SUN DUCT

The use of daylighting in a room is certainly better than the use of l amplight alone, due to its undubitable chromatic properties and correl ated psychological effects. In many cases, especially for pre-existing buildings, the income of daylighting appears an unsolvable problem fo rcing people to use intensively electric lighting. In this paper the u se of a component for natural lighting of a space with no direct openi ngs to the exterior is presented. The project was carried out in a bui lding situated in the old town centre of S. Colombano al Lambro near M ilan.
