| 中文摘要 | 生態建築的設計包括調整建築物外殼的材料、面積、開口方位及傾角,以阻隔日射量之熱源並有效收集太陽能之日射量,所以模擬日射量依平面的方位與傾角之定量變化為本文之研究目的。三種等向散射模式包括Liu and Jordan (1962)之二維等向模式、Klein and Theilacker (1984)之等向散射模式以及Badescu (2002)之三維等向散射模式作一比較後,採用K-T模式為本文之理論基礎。模擬宜蘭市在不同方位及傾斜角之各月平均日射量,結果發現建築物夏季東西向立面日射量最大,南向立面在夏季以外時間可有較大日射量。太陽能收集板除在水平面有最大之日射量外,全年以南向傾角30° 為最佳選擇;涼爽季節仍以南向傾角30° 之平面可以得到較高之日射量,炎熱季節則以東西向傾角30° 之平面可得到較高日射量;上述結果可提供生態建築設計之準則。 |
| 英文摘要 | The design of ecological architecture includes blocking the heat from solar radiation and collecting solar energy by adjusting material, area, opening orientation, and slope of architecture's shell. The objective of this study is to simulate solar radiation by numerical method with varied orientation and slope. Three isotropic diffused models, which include the 2-D model developed by Liu and Jordan (1962), the model derived by Klein and Theilacker (1984), and the 3-D model suggested by Badescu (2002), are compared and resulted that the K-T model is appropriate for simulation. Simulation of monthly average daily solar radiation of architecture's facades in Ilan city by using K-T model results that vertical surface facing east and west has more solar radiation than facing other orientation. The south facing vertical surface has the most solar radiation during seasons other than summer. Simulation of monthly average daily solar radiation of solar collector results that the horizontal surface has the most irradiance. Surface facing south with tilted angle of 30° is the better choice for solar collector during the whole year. The same orientation and slope is appropriate for cooling season. Surface facing east or facing west with tilted angle of 30° is suitable for hot season. The simulation results could help the design criteria of ecological architecture. |
