Outline of Final Research Achievements

Daylighting in buildings is recommended and advanced daylighting systems have been developed. In order to aid architects in choosing a suitable daylighting system, several simple indices showing properties for energy-saving and visual comfort are proposed in this study.
Daylighting systems are classified to identify their required properties. Distribution of daylight in systems which utilize mirror reflection can now be modelled by advanced lighting simulation algorithms. Both the visible light and heat gain of daylighting systems (interior blind and exterior blind) are measured by using a special measurement device. Equivalent luminous efficacy, the effective luminous flux coefficient, and the reduction factor of discomfort glare are newly defined. These indices for daylighting systems are measured for standard outside conditions, which are determined from the frequency of climatic conditions. A matrix of these indices is presented.
