Optimization of Lighting in Commercial Premises

Abstract:

The daily and artificial lighting in the interior are the key elements shaping the visual environment and health aspects. Much attention is given to artificial lightings, but because of the benefits of natural lights, there is the need to study their optimization. This is the basis of this study. In effect, the goal of this study is to optimize the natural and artificial lights. This Diploma Thesis presents the optimization of natural and artificial lightings in public buildings or commercial premises. The method applied was to have a detailed numerical simulation of natural (daylighting) and artificial (electric) lightings by allowing interior illumination levels assessment. For the natural light, vertical windows were considered, while for the artificial light, illumination was done using the KNX lighting control systems. For the purpose of this study, measurements were taken at various observation points in the Laboratory, and an open-source software (Dialux Evo) was used to produce numerical simulations at the observation points with the blinds set at various open positions, using the KNX lighting control systems.
