Dosimetric measurement of lighting conditions in office environment

Abstract The aim of the paper is to present partial outputs from continual measurement light conditions in office environment during common work activity. volunteers worn head mounted dosimetric devices – Lightwatchers, collect individual and realistic data contrary fixed photometric devices. confirm that natural activity workers has a great influence on recorded illuminance levels. It shows an overall decrease levels vertical plane facial area when compared standalone sensors. Since total amount received through eyes important for proper entrainment our biological system, adjustments office´s lighting design needs be taken into consideration.
