Daylight Colour and Pattern in Built Environments: A latitudinal study of daylight and user responses to the varying colour of skies in built environments using spectral simulations.
In an increasingly urbanised world, it is crucial for design and planning policies to prioritise liveability, wellbeing and health of urban inhabitants. Daylight is an integral tool for these aspects, and building professionals should consider not just the quantity of daylight but also its spectral characteristics in relation to the built environment. There is growing research evidence highlighting the impact of daylight and its spectral characteristics not just on the visual aspects but also on human health and well-being, influencing factors such as sleep quality, depression, and stress. Therefore, it is essential to advance tools that can predict and accurately represent the spectral characteristics of our environment for design and research purposes. Predicting daylight in built environments is predominantly based on assessing lighting quantities rather than its chromatic or spectral characteristics. This is because lighting simulation tools have relied on luminance-based sky models that lack both the colour and spectral information of daylight. While such a modelling framework gives a good approximation of daylight availability, it does not help evaluate scenes based on diurnal, seasonal, or geographical colour or spectral differences of daylight. This EU-funded DAYCOP project addressed these challenges by establishing a framework for generating location-specific spectral daylight data suitable for integration into various daylight spectral simulation platforms. This integration enhances daylight planning for indoor and urban environments while facilitating research into characterising geographical variations in daylight, its perceived qualities, and non-image-forming effects.

Project objective
Three-quarters of the global population will be urban by 2050. To ensure the liveability, sense of place, and quality of life in new expanding urban areas, urban planning policies should consider spectral characteristic of daylight and the built environment. The colours and patterns we see around us, at various scales of the urban environment (city, neighbourhood, or street), are a complex interplay between the spectral distribution of daylight and spectrally-specific reflectance of surfaces in the space. Daylight sculpts the colours and patterns of our environmental perception, giving architects, urban and city planners an effective strategy to create spatial experiences, visual impressions of character and behavioural responses. However, current daylight simulation workflows used by building professionals do not account for colour renditions nor associated patterns of daylight. Spectral sky data is not readily available. Spectral simulations (to accurately predict colour and patterns of daylight) are computationally intensive and require further research and validation. Finally, research is inconclusive on how colour and patterns of daylight influence our environmental perception. My proposal is threefold. First, validate spectral sky models in existing spectral simulation platforms for different latitudinal regions. Second, define spectral dynamics of daylight in diverse urban environments (plaster, brick, reflective facades or spaces with vegetation) and latitudes (polar, temperate or equatorial). Third, conduct user perception studies in built environments with varying regional skies. This will help formulate design guidelines that consider characteristic qualities of daylight (colour and patterns) with local preferences. At the end of the two-year fellowship, I aim to expand my publication record, research expertise and create local and international collaborations, to establish myself as an independent researcher ready for a tenure track position.
