Influence of the coupling between daylight and artificial lighting on thermal loads in office buildings

The analysis of the global energetic needs in an office building has to take into account the daylight and artificial lighting which are tightly coupled. The luminous and thermal behaviours of a room are influenced by the artificial lighting that generates thermal loads and by the natural lighting coming from the windows. This paper deals with the foreseen energy balance of an office building with regards to the technological and architectural solutions. This study has been conducted with EDF Research and Development, Services, energies and living spaces Department. A global analysis is needed for a consistent approach of Energy Demand Save Management [Etude de l’influence de la complémentarité entre l’éclairage naturel et l’éclairage artificiel sur le comportement thermique des bâtiments tertiaires, Thèse Université de Savoie, March 2001, 213 pages].
