Abstract

Highlights:Graphical/Tabular Abstract  Investigation of modelling indicators  Comparison of the modelling indicators with each other  Comparison of the findings with the visual assessments of facial impressionThe appearance of objects' features like form, texture and human faces are examined under the heading 'modelling' in the literature and various modelling indicators have been proposed to define the appropriate conditions regarding modelling. Figure A. Calculation results for some lighting scenarios according to the proposed modelling indicators in literature Purpose:The aim of this study is to compare and evaluate different modelling indicators in two phases. Firstly, the comparison is based on different lighting scenarios that are created in a lighting software. Subsequently, calculated modelling indicators are compared with the visual assessments of a previous study. Theory and Methods:Modelling is a lighting design criterion and is described as the balance between directional and diffused light. The proposed modelling indicators were defined under certain lighting conditions. The calculation of the mentioned indicators for different lighting scenarios was therefore considered important. Thus, it may be possible to determine the indicator that may be considered most appropriate to be applied for any lighting arrangement. For this purpose, different lighting scenarios are generated in a model room created in the DIALux lighting program. The proposed indicators are calculated for each lighting scenario and the results are compared. The calculations are conducted for the eye height of a sitting person. The calculation results obtained in this phase are then compared with the visual assessments of facial impressions performed in a previous study. The model room created in the lighting program was the simulation of the mock-up room in which the visual assessments were performed. Results:The comparison of the calculated modelling indicators with each other showed that they are not coherent with each other. The calculation results were also not consistent with the visual assessments for each scenario. Conclusion:The results of this study showed that more research on modelling is needed. Identification of a modelling indicator is required to be used to determine the modelling condition for all possible lighting arrangements.
