Daylight-Transfer Systems: Physiological And Energetic Advantages

Abstract

Daylight-transfer systems are devices designed to operate according to the law of reflection: they collect and transfer it to rooms lacking in light. On the whole, possible applications can deal with rooms which do not communicate directly with the outside. For instance, it can be the case of both basements and large-sized buildings like those devoted to the service industry. In recent years, the considerable attention devoted to sustainable development has prompted planners to reconsider the use of daylighting in architecture. Current research, partly examined in this article, aims at producing a range of systematised products and techniques according to some specific characteristics in order to highlight the advantages of these systems in terms of energy conservation as for essential artificial lighting and, consequently, to contribute towards decreasing the use of non-renewable sources of energy and related problems about sustainability.
