The impact of scale when using models of daylight analysis

Sammanfattning: The study examines the issue of scale regarding models when analyzing daylight, which scale is the most representative of a real space. There have been previous studies done regarding scale model and daylight, however, they do not look at how the scale itself can affect the experience of daylight. The use of the architects’ already built scale model can be seen as valuable for light designers when evaluations and visualizing daylight in a real space. However, the use of the architect's scale model depends on its scale, hence why this study is being conducted. The aim of this study is to evaluate the effects the scale has on daylight visualization with scale models. This study began with conducting a small literature study regarding daylight, scale models, visual perception and practical consideration when using scale models. The method was designed thereafter. By choosing a real room to base the scale models on, three scales were chosen, 1:50, 1:20 and 1:10. Thereafter the questionnaire was designed by using the analyzing method PERCIFAL as a base. The result of the study showed the subject's answers regarding; light level, shadows, light distribution and specular reflections. As well as a question regarding which scale model the found most representative of the real room and why. The compiled data showed which scale model was the most representative of the real room. The results show a difference between the different scale models and a correlation to the real room is seen. In conclusion, the scale model can be used to estimate and visualize the daylight within a space. However, the scale must be regarded and looked at so the chosen scale can represent the real space, which allows for an easy view of the model.
