A high luminance contrast between windows and surrounding surfaces can increase the risk of discomfort glare, which diminish office workers’ satisfaction productivity. Accordingly, it lead to occupant interventions, such as drawing window blinds or increasing electric light levels, are intended enhance indoor visual comfort but counterproductively act energy consumption. Increasing areas using a supplementary lighting system, wall-washing with emitting diode (LED) linear luminaires, could reduce glare arising from windowed walls. This paper reports on results study in typical room Brisbane, Australia. The outcomes this indicate that creating 11:1 12:1 wall an 45% window-to-exterior-wall ratio LED system leads improved subjective assessments appearance. suggest enhancement significantly windows, well diminishing likelihood users intending turn ceiling lights move blinds.
