This study combined light and illumination measurements, indoors and outdoors, with emphasis on the daylight health benefits for building occupants, particularly for older age groups and those with limited access to the outdoors.
The study setting was a room including openable glazed windows facing south and facing west. Continuous illuminance data was recorded outdoors and indoors using data-loggers and a portable wearable device. Additional simultaneous light spectra/luminance/illuminance measurements were recorded three-times on one day, with open or closed windows and curtains.
Results highlighted the amount/quality of indoor daylight access resulting from façade orientation combined with four window and curtain configurations. Significant increased melanopic equivalent daylight illuminance (m-EDI) levels were observed with glazed windows fully open. In particular, for people limited to indoor settings, this highlights the importance of accessibility to and the adaptability of building façade components
