The importance of parameterization in simulating artificial lighting in indoor environments

Abstract

Digital technologies play a crucial role in assessing the luminous performance of buildings, facilitating the search for more efficient design solutions. However, it is important to emphasize that without proper parametrization of the elements used in simulations, the obtained results may be inconsistent, affecting both lighting and shadow effects as well as the calculated values. Therefore, the objective of this study is to elucidate the impact of luminaire parameterization on internal artificial lighting studies by manipulating their input parameters, such as luminous distribution, efficiency, and angle of incidence. In this context, it is relevant to mention the use of Revit and DIALux Evo software. Revit was used in both constructing the test environment and conducting the simulations. DIALux Evo was selected due to its specialization in the subject, serving as a reference to assess the accuracy of the simulations performed in the former software. It is worth noting that while the scenario generated by Revit closely approximates DIALux Evo, it tends to be somewhat optimistic regarding illuminance, which may result in undersizing the lighting project.
