Colour of reflected light: a determinant of sustainable spatial function

Abstract According to the works of W.R. Ott, we are an ‘indoor species’, spending on average, 87% our time in closed environments [1]. Our long interaction with indoor surroundings, creates need for such spaces be sustainable, bringing factors affecting user behaviour and consequent usage patterns under microscope. This is empirical study investigating if reflected light carries a component colour taken from pigmented surfaces this has any influence usability space its pattern. The conducted domestic interior student housing Stockholm artificial conditions that were static constant. period was limited weekends observe free will. It comparative analysis between two dining having identical architectural lighting attributes, walls as only change sets. There separate groups similar age groups, needs schedule. includes four stages observation data gathering by adopting qualitative quantitative methodologies. effects perception hence cannot negated completely, even more needed prove same. results can used question photometric instruments their inability detect aspects light. also helps underline involvement qualified designer making beginning till end interpreting interactions surfaces. findings may considered stimulus developing set standards coloured given environment measurable parameter sustained environments.
