就建築外部環境的處理上,綠化植栽的利用是綠色建築計劃可以考量的手法之一,除了可降低二氧化碳排放量及提供良好的視野環境之外,植物本身遮蔭及葉面蒸散作用的效果,可以用來降低周圍環境的溫度,這些作用及效果在理論上與一般經驗上大抵已獲得認同與理解。本論文之主要目的即是利用紅外線熱像技術與熱傳理論觀測,探討並驗證綠化植栽對於都市中建築環境降溫效果的可視化影響與定量分析。在利用紅外線熱像技術的觀測成果上,已明顯地将建築物綠化之降溫效果可視化顯現,加上綠化牆面熱量傳導及表面溫差之量測分析,換算相當熱組係數也加強量化顯示綠化植栽之降溫效果。研究成果驗證立體綠化植栽對建築外牆有明顯之降溫效果及對環境之良性影響。
The utilization of green plant is a considerable solution for improving environment in greenbuilding design.Green plant can not only reduce the CO2 emission and supply good visual landscapebut also can reduce the surrounding temperature of building.The effects are comprehensibleby the common experience and heat-environment theory.The main propose of this research is toverify the green plant effects for building wall by Infrared Ray(IR)technology and quantitativeanalysis.The results of IR observation obviously show the visible reducing temperature effects ofgreen plant on building wall.Furthermore,the quantitative analysis and the imitative heat-resistantcoefficient also show the same effects.The results verify the qualitative impression of green planteffects by visible and quantitative observation.
