A light of Play: Demystifying Daylight-driven Spatial Sensation Modeling through Image-based Analysis

Abstract

Our study aims at evaluating the daylight model as a design approach, facilitating the architect to improve spatial quality, and making sense of spatial sensation of a daylight model through a quantitative method of sequential and time-based image analysis. We investigated two spatial criteria affected by light, namely calming and exciting [10], defined by four light indicators: contrast, intensity, uniformity, and colours. The mechanism of the experiment was performed on the process of a conceptual design of a museum of modern art in Bandung, where design decisions of architectural layout and element, space, and form were defined and determined based on the result of analysis over series of rendering images instead of conventional diagram-to-plan approach. In this method, each image contains measures of the predictive perceptual effect of daylight for the decision-making process. On the notes of this study, the quantitative and formal approach through image-based analysis has its benefit to model the intangible aspect of architectural design and potent to improve objective measures of spatial quality.
