As an observatory of the International Daylight Measurement Programme (IDMP) of the Commission Internationale de 1'EcIairage (CIE), one of the authors started measurement in January 1993. Based on minutely data gathered over the past nine years on solar radiation and illuminance, this paper has sought luminous efficacy of each of direct, diffuse and global illuminance of daylight. An estimated equation, which regarded luminous efficacy of daylight as the constant and involution of the corresponding solar radiation volume and coefficient of the involution as the function of solar altitude, was employed. Then, estimated gaps were made clear quantitatively by repeatedly examining luminous efficacy of daylight according to solar altitude and cloud ratio. This paper shows that it is proper to make use of luminous efficacy of daylight in accordance with necessary estimated accuracy.
