Nowadays lighting criterions for internal spaces can be widened; because there is need to not only stimulate properly the human visual system but also to entrain the non-visual system of users or inhabitants. Since the medical discoveries in the field of light influence of circadian system, a system that controls our daily body rhythms, gave us basic principles how it works, we can use advanced methods how to evaluate internal light climate in the buildings. We focused on the colours of wall finishes, which influence the spectral composition of the light that enters the eye of inhabitants in specified locations. A set of specified applied colors were compared to the neutrally coloured walls. Also the effect of external shading obstruction was examined in this study. This observation, based on the spectral examination of light conditions, may provide more complex overview on selection of internal surfaces colours in long-term occupied spaces, taking health and wellbeing into consideration. |
