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.

Spectral simulations of daylight for urban environments As urbanisation increases worldwide, planning policies that assure liveability and quality of life in new urban areas are required. Building professionals should consider the spectral characteristic of daylight in relation to the built environment. However, current daylight simulation workflows do not account for colour performance or associated daylight patterns. Spectral sky data are not yet readily available, and research on the impact of colour and patterns of daylight on our environmental perception is inconclusive. The EU-funded DAYCOP project will address these challenges by validating spectral sky models in existing spectral simulation platforms, defining spectral dynamics of daylight in urban environments and latitudes, and conducting user perception studies in built environments with differing regional skies.Objective Three-quarters of the global population will be urban by 2050.
