Technical-Economic Evaluation of the Effectiveness of Measures Applied to the Artificial Lighting System of a School

Ensuring optimum interior lighting is a topic of great importance, as this influences not only the well-being users but also optimal performance visual tasks. Lighting can be natural, if sufficient, it compensated with artificial lighting. This study highlights methodology for designing new system that takes into account both technical and economic aspects. The method was applied to an existing school located in southern Italy, which electricity consumption related current system. chosen being representative construction type layout many local schools. In addition, coexistence several tasks different design requisites (e.g., illuminance levels) makes very complex environment. modelled Google SketchUp imported Daysim simulate yearly hourly daylight indoor contribution. Dialux Evo has been used results show reduction energy 33% simple replacement fluorescent luminaires LEDs, while LED lamp dimming modulation rows leads 95% compared state.
