| Summary: | 碩士 === 國立臺灣科技大學 === 建築系 === 95 === The daylighting application can not only be applied to save the lighting power use , it also can reduce the lighting appliance produce heat to make air-condition load. This research mainly focuses from the measure an illumination on a building in daylighting, and according to the windows, room scale, interior-materials reflection rate and shading devices, and set-up scaling model to equalize a building, furthermore measure an illumination on the same site in the scaling model. Tried in daylighting, discuss and analyze are both illumination in the building and scaling model, it find their correlations and interior illumination forecast formula. Verify factors, solar azimuth, solar altitude, open window rate and shading depth, effect measure and forecast a illumination in the building.
The part of illumination forecast formula and scaling model, has in total 4 points, nearby room deep’s 2 points were effected with low direct light. The correlation analysis R square is over 0.5 is more accuracy; nearby window’s 2 points were effected direct light highly, in correlation analysis R square isn’t expect accuracy. In the part of illumination in the building and scaling model, the correlation analysis R square is over 0.97 and 0.96. It is well accuracy that illumination in the building and scaling model. The last part of interior illumination forecast formula and a building, nearby window’s point has very high accuracy, that correlation analysis R square is 0.9396; nearby corridor’s point has accuracy lower than nearby window’s point, that correlation analysis R square is 0.8375. The illumination calculate formula applies to forecast in a building has high accuracy.
