LUMINOUS PERFORMANCE AND ENERGYSAVINGS OF A SOLAR TRACKING MIRRORSYSTEM FOR DAYLIGHTING

摘要

The aim of the present study is the proposal of a novel tracking mirror system for the daylighting of deep interiorrnspaces, such as commercial buildings, underground railway stations, parkings, etc.. The analytical approachrndemonstrates that it is possible to supply an acceptable workplane illuminance for 6/8 hours per day during thernyear in southern Italy. The experimental data, obtained by means of a physical model, support the theoreticalrnanalysis. Benefits in terms of energy savings and illuminance level, especially in clear sky conditions, arernoutlined.
