As living in urban environments increases, the impact of city design on the health of individuals becomes more relevant. Cities have shown to negatively affect individuals' circadian health. This thesis investigates the influence of façade and city lighting design on indoor circadian lighting availability, addressing the increasing prevalence of circadian disruption in cities caused by poor daylight access and excessive artificial light exposure.
The research introduces a workflow that evaluates how façade designs and urban lighting choices affect circadian light exposure within homes based on open data sources. By creating a tool capable of simulating these effects for individual floor levels on an urban scale, the study provides a method to assess and optimize architectural and urban design for circadian health with public information in a large-scale manner.
The results aim to bridge the gap between available 3D urban data and practical applications, offering design strategies that improve indoor circadian lighting availability and contribute to healthier urban living environments.
Key findings prove the misalignment of indoor circadian lighting availability with human needs in cities, and show the importance of window size, floor level and façade orientation in mitigating circadian disruption caused by the urban context. Next to that, it shows the negative impact city lighting has on indoor circadian health, for which design suggestions are done.
