Abstract: The impact on daylight quality perception, of three windows of similar visual transmittance but different colour (blue, neutral, bronze) was investigated. Participants (n=36, mean age 23.8 years) were seated with their upper body immersed in a scale model (1:4) replicating an office room composed of four walls and a changeable window (blue, neutral or bronze) oriented towards the south-east direction. On separate sessions (one for each window glazing), participants were asked to evaluate the luminous conditions in the room according to the following qualitative factors: visual comfort; naturality; pleasantness; precision (of details and textures); light level. Participants were also asked to evaluate their level of arousal using a sleepiness scale (KSS) at the beginning and end of each session. Mixed model analyses revealed statistically significant higher scores for the factors pleasantness (p=0,003 and p=0,017 when results from the oral and written questions were combined), comfort (p=0,015) and daylight quality (p=0,044) for the bronze window glazing compared to the blue and neutral glazing. The neutral glazing was also preferred over blue for pleasantness (p=0,021). Paired t-test analysis from the KSS results indicated a slight decrease in the level of arousal in presence of the blue glazing. Overall, the thesis shows that there appears to be a clear preference for ambient light filtered through bronze window glazing compared to blue window glazing.
