Definition and Assessment of a BAC Factor for Estimating Electrical Consumption of Outdoor Lighting

Abstract

The BAC factors method was introduced by the international Standard EN 15232 for a rough evaluation of energy savings in buildings obtained thanks to automation. The above standard considers the building’s services such as heating, cooling, ventilation and lighting and takes into account automation on the basis of assumed usage profile for the related technical installations. However, the standard does not refer specifically to the automation of outdoor lighting systems such as those serving gardens, entrance walkways and passages around the building and supplied by it. In this paper, the authors propose a method for evaluation an outdoor BAC factor for lighting system considering various scenarios. The method can be seen as a possible extension of the one proposed by EN 15232 and can be used with the same purposes.
