Outline of Final Research Achievements

In order to propose design index for office lighting, applicable to task and ambient lighting with active use of daylight, subjective experiment including real daylight as an experimental parameter, was conducted. As the result, 1) For both task lighting and ambient lighting, analysis of luminance image is useful to judge their applicability, 2) Numeric indices for appropriate lighting condition applicable to both electric lighting and daylighting were proposed, and finally 3) Use of luminance image analysis could realize appropriate hybrid lighting with electric light and daylight was suggested.
