A Study on Prediction Method of Interior luminance from a Movable Louver Blind System luminanted by the Direct Sunlight |
| Abstract |
Using daylighting in commercial buildings may significantly reduce electric lighting load if appropriate movable louver blind system are used to adjust two-dimentional window.For the purpose, this paper is to give a general calculation method of the louver blind system to predict daylight illuminance propability on working plane for hour of day for month of year which has south-, east-, north-, and west- facing office window in the Seoul area.A calculation based on integral equation for interreflections in unit-cell of venetian blind system and configuration factor of each part of window with different slat angle was developed. |
