Energetic and Economic Comparison of Lighting Systems in Historical Buildings: A Case Study

One of the greatest strategies in order to reach European energy goals can be considered the reduction of the primary energy consumption caused by the existing building. In order to reach a sustainable approach, the refurbishment of historical and traditional buildings in a holistic view must be taken into account. Between the various design processes, lighting aspects are fundamental, considering all the possible ways the building is used by the final user and also according to the climate context parameters. In the present study, a numerical simulation was performed by DIALux software on an existing Coastal Tower placed in Apulia Region, supposing to design the existing building as an exhibition hall. Using bibliographic data, a comparison between LED lamps and halogen and compact fluorescent lamps was carried out. Moreover, an economic and energy analysis was carried out by EcoCALC software demonstrating the potential energy and economic savings when using innovative solutions.
