A study on the prediction of the interior luminous environment based upon daylighting |
| Abstract |
The luminance distribution on the sky hemisphere is very important and necessary as a reference sky to all daylighting predictions and calculations in practical daylighting design. Therefore, the daylighting prediction method has been contrived for the investigation of daylit interior luminous environment in order to apply the mathematical data which character reflection properties of building materials. In accordance with the number of the luminaires which will satisfy the required interior illuminance level is to be calculated with the ordinary lumen method. The proposed luminaries are to be laid out below on the ceiling in order to illuminate the working plane as well as possible. The total amounts of the electric powers cosumed by the artificial lighting in the daytime during a reference period can be theoretically estimated from the numbers of the lamp. |
