Light Passage

Description

The relevant human medical literature points out the epidemic occurrence of different lacks of radiation phenomena of the spectral range of the terrestrial solar radiation. As the stay indoors is currently over 90 % of the lifetime of people in post-industrial environment, the interior radiation offer in the relevant spectral range is investigated. It is assumed that technically functional glazings as they are used in the building practice, show - according to their thermal and visual ergonomic specifications - for different spectral ranges differing permeability. The psychological suitability of the corresponding passage residual spectra for the permanent stay in the interior is determined by the folding of spectral distribution curves with selected physiological sensitivity curves as those of vitamin D3 photosynthesis, the forming of erythema or melatonin suppression to determine the radiation data obtained during the day. Accordingly, different glasses are evaluated and transparent alternative materials investigated. Finally, based on polar sun path diagrams preferred alignments for the positioning of openable and transparent surfaces in the building envelope are revealed.
