The impact of surface properties on interior daylight availability : Case study of a Swedish office adapted for residential purposes

Bálint Palmgren, Oscar LU orcid (2026) 6th Central European Symposium on Building Physics In Lecture Notes in Civil Engineering 2. p.1067-1079
Abstract
Daylight is crucial for the well-being of individuals in indoor environments, providing numerous physiological and psychological benefits. Achieving satisfactory daylight levels can be particularly challenging during adaptive reuse of existing buildings for new purposes. This study determined the feasibility of adapting an office for residential use by assessing interior daylight availability and the effect of surface properties. The effect of six parameters on two static daylight metrics was evaluated across 24 rooms on two floors of a Swedish office building. Daylight simulations were conducted using Radiance within the Grasshopper® environment in Rhinoceros®. The effect of the parameters on both daylight metrics was determined through... (More)
Daylight is crucial for the well-being of individuals in indoor environments, providing numerous physiological and psychological benefits. Achieving satisfactory daylight levels can be particularly challenging during adaptive reuse of existing buildings for new purposes. This study determined the feasibility of adapting an office for residential use by assessing interior daylight availability and the effect of surface properties. The effect of six parameters on two static daylight metrics was evaluated across 24 rooms on two floors of a Swedish office building. Daylight simulations were conducted using Radiance within the Grasshopper® environment in Rhinoceros®. The effect of the parameters on both daylight metrics was determined through global sensitivity analysis using the method of Morris. The study showed that daylight levels were expected to exceed the legal minimum. However, the variability due to the effect of studied parameters was such that daylight levels could fall below the legal threshold under certain conditions. The visual transmittance of glazing in apertures had the largest effect on interior daylight levels, while the reflectance of major room surfaces influenced the uniformity of daylight distribution more. All parameters displayed nearly monotonic or slightly non-linear relationships with at least one of the daylight metrics. While the study confirmed that the proposed adaptation was able to achieve adequate interior daylight conditions, further research is necessary to produce generalizable conclusions on daylight availability regarding adaptive reuse of office buildings for residential purposes.
