摘要註:	當陽光直接照射建築物時，建築外殼的開口與牆體會因熱傳作用而導致室內溫度上升。除了在炎熱季節無法提供使用者熱舒適的室內環境之外，也造成空調設備過高的能源耗用與用電成本。因此，如何能讓建築外殼降溫已成為低碳建築的最基本設計策略。例如，運用遮陽網就是其中之一。本研究已完成在鋼鐵表面、清玻璃、反射玻璃、馬賽克磁磚牆面或水泥粉光牆面採用遮陽網的降溫效果分析。主要研究成果的摘要如下：1. 六種遮陽網的日射遮蔽率大小排序為：80%黑網 > 70%黑網 > 80%銀網 > 80%綠網> 60%黑網 > 50%黑網。2. 若遮陽網直接被覆在材料表面，相較於無遮陽網時的表面溫度，原則上，其表面溫度會大幅的增加。˙清玻璃表面溫度的增加約10℃。˙鋼鐵表面，因其較高的放射率與熱傳導本質，在中午期間的增溫現象不明顯，大部份是降溫約1.5℃。但在白天的其他時間，鋼鐵表面溫度的增加約2~5℃。3. 若遮陽網在玻璃上方20cm，相較於無遮陽網時的表面溫度，其玻璃表面溫度變化為：˙清玻璃表面溫度降低約11℃。˙反射玻璃表面溫度，在7~9時升高約6℃；在10~16時降低約2~6℃。4. 若遮陽網在材料表面上方30cm，相較於無遮陽網時的表面溫度，原則上，都能讓材料表面產生明顯的降溫效果。˙清玻璃表面溫度的降低約2℃。˙鋼鐵金屬表面溫度的降低約15℃。˙水泥粉光牆面的表面溫度降低，南向牆面約11℃，西向牆面約10℃。˙馬賽克磁磚牆面的表面溫度降低，南向牆面約2℃，西向牆面約6℃。5. 若相較於周遭的氣溫，雖然遮陽網會讓材料表面溫度下降，但仍高於當時氣溫，可能高達5~28℃。但在夜晚，除了在垂直牆面的情況，都是低於氣溫，最大約3℃。 The effect of direct sunlight on building skin during the hot summer will raise the interior air temperature due to the thermal transfer taken place in the openings and walls on building envelopes. Such kind of thermal behavior cannot provide a comfortable indoor environment for occupants in the hot season and will also lead to extremely high energy consumption and electricity cost of the air conditioners. Therefore, how to lower the temperature of the building envelope have become the basic design strategies for low-carbon buildings. The application of solar screens is one of the commonly-used examples. This study had analyzed the cooling effects of varied solar screen on different material surfaces such as steel, clear glass, reflective glass, mosaic tiles, and cement mortar. The key research findings are as follows:1. The rankings of solar transmittance of the six solar screens are: 80% black net > 70% black net > 80% silvery net > 80% green net > 60% black net > 50% black net.2. If solar screens directly cover the building material surfaces, the surface temperature will raise largely in principle when compared with that without covering.• The surface temperature of clear glass increases about 10oC at a maximum.• Owing to the high emissivity and thermal conduction of the steel surface, its temperature change is unapparent during the noon, which is generally decreased by 1.5oC, but the temperature will increase about 2~5oC in other periods of the day.3. If the solar screens are 20cm above the glass, when compared with the one without solar screens, the temperature changes of two types of glass surfaces are as follows:• The surface temperature of clear glass is turned down by 11oC.• The surface temperature of reflective glasses increases 6oC during 7:00~9:00 am but decrease 2~6oC during 10:00 am~16:00 pm.4. If the solar screens are 30cm above the material surfaces, the noteworthy cooling effects are emerged on all material surfaces in principle when compared with the uncovered one.• The surface temperature of clear glass reduces 2oC.• There are 15oC falls on the surface temperature of steel.• The surface temperature of cement mortar wall also decreases, by 11oC on the south wall and by 10oC on the west wall.• The surface temperature of mosaic tiles decreases, by 2oC on the wall southward and by 6oC on the wall westward.5. Although the solar screens can make the surface temperatures of building materials lower than the uncovered material surfaces, they are still 5~28oC higher than the surrounding air temperatures at that time. In the night, the surface temperatures of building materials are lower than the neighboring air temperatures except the vertical walls, with a maximum value of 3oC.
