- Abstract
- Reflective dome-type artificial skies are effective tools in daylight research and design. However the artificial skies need to
be designed carefully for design if they are to reproduce a desired sky luminance distribution faithfully. For daylighting studies
during the building design process, the CIE overcast sky condition is the standard sky condition. But calibrating the luminance
distribution within artificial skies to reproduce the CIE overcast sky is on highly time-consuming and difficult job. Therefore, a
method to improve the calibration process is required. In addition, since the artificial skyes have a restricted space, they cause
several measurement errors by things such a scale and position of models.
The purpose of this study was to develop calibration method for dome-type artificial skies using the RADIANCE program
and to study the characteristics of measurement errors in the artificial sky. An existing artificial sky in H university was
calibrated so that it reproduce the standard CIE overcast sky. The size and position of the physical scale model in the specific
artificial sky were identified to be major factors for measurement errors.
