Project description:Many modem and a la mode trends in area of creation indoor light climate (natural and artificial) are not in harmony with new medical information about non-visual influence of light on health and comfort of indoor environment occupants. New types of glazing systems and techniques of light environment regulation can change spectral composition of light, its intensity and dynamics in such amount, that people in buildings are in "biology darkness" from chronobiology point of view. Such situation can arise even in case that indoor environment satisfies all current requirements and codes. Research is focused on enhancement of circadian photometry, which is based on action spectrum for melatonin suppression in humans. Creation of the integral system of requirements and criteria for design and assessment of indoor light environment from point of view of non-visual aspects is planned on this base including experimental methodologies and material parameters. These parameters will be tested in model rooms in real conditions of light climate and will be generalised by computer simulations. Impact of chosen types of glazing on circadian rhythms will be studied in real indoor environments with long-lasting stay of persons by medical methods. Strand of the project is also the upgrading of existing or the creation of new standard or other regulation instruments for creation of light climate in buildings to achieve protection and strengthen public health.
