Abstract: This paper reports and discusses some measurements of daylight and solar radiation during the period from December 1993 to November 1998. To obtain data of daylight and solar radiation, measurements have been taken of illuminance and irradiance on horizontal (global and diffuse) and four vertical planes facing north, east, south and west. Instantaneous values of illuminance and irradiance at one-minute intervals have been recorded in these measurements. The two horizontal diffuse sensors were each fitted with a shading ring which was adjusted manually every day. The data presented in this paper were calculated from the average of ten-minute readings of illuminance and irradiance. Direct solar illuminance and irradiance were calculated by subtracting diffuse from global, and each luminous efficacy was calculated as the ratio of average direct solar illuminance to irradiance.
