摘要

近年來，全球暖化造成的環境危機日益嚴重，因此，永續節能成為建築設計的重要議題。本研究將此議題在建築皮層上作探討，主要以光能源作為轉換能源的對象，其透過整合仿生機制與互動技術進行操作，企圖從植物的向光特性探索光能源轉換的機制，再以互動技術落實追光狀態的空間形式設計，並於都市中閒置空間為出發點，以期發展具向光性的互動皮層雛形，稱之為”都市原葉體”。此雛形除了創造空間在能源使用上能自給自足的設計外，並賦予都市中閒置空間新的意義。

為完成以上目標，本研究分四個步驟進行 : 1.文獻回顧 : 歸納出皮層與肌理在建築中所扮演的性質，再將植物特有的向光性作為仿生的定位，由數位運算與互動概念完成其架構統整。2.案例分析 : 觀察各案例之設計概念與互動機制，如感測方式、互動行為、仿生模式等，幫助思考未來操作時的設計發展。3.設計先期研究 : 探討本機制的實作組構方式，觀察仿生向光如何影響植物紋理與活動機制的變化；再試以摺紙、關節、桿件等模型研究變動性；加上互動技術測試，用實體資訊輸入虛擬動畫輸出的方式模擬互動過程；最後選擇自重小、規格適切，並符合本研究需求的太陽能板配合設計。4.設計實驗 : 統整以上資料，觀察都市中閒置空間的採光優勢，以天橋作為設計對象，分析其空間、日照、事件等，置入本設計，定義天橋在都市中的另一種性質。

鑒於上述分析，選擇中華路景觀橋為基地，分析該天橋現況條件、日照情形及空間計畫，將都市原葉體置入於橋體上部作為接收光源的皮層，透過互動技術調適向光角度，達到仿生向光的追光狀態，將轉換的光能源支應作基地中空間需求，並加入新的事件以活化天橋舊有機能。透過本次設計操作，期待更多的閒置空間能作為可再生能源的操作對象，提供都市空間需求一種新的可能性。

The environmental crisis caused by global warming is getting more and more serious in recent years, therefore sustainable energy saving becomes an important issue of architectural design. This research discusses the issue from the building skin mainly by taking the light energy as the subject of energy conversion. It completes the operation by integrating the bionic mechanisms and interactive technology so as to explore the mechanism of light energy conversion through the phototropism of plants. And then it implements the space form design of the follow spot state by using the interactive technology. After that, it starts with the unused urban spaces to develop a phototropic interactive skin prototype which is called “Urban Prothallus”. This prototype not only creates a design that the energy is self-sufficient in the space but also gives the urban city spaces a new meaning.

To achieve above mentioned goals, this research was carried out by four steps: 1) Literature review: concluding the role that the facade and texture played in the buildings, and then chose the unique phototropism of the plants as the biomimetic positioning. After that, it completed the architecture integration through digital computing and interaction concept. 2) Case study: observing the design concept and interaction mechanism of various cases, such as the sensing method, interaction, biomimetic pattern, etc. so as to help thinking about the design development of the future operation. 3) Pre-design research: discussing the practical structural pattern of the mechanism and observed how the bionic phototropism impacted the change of the texture and activity mechanism of the plants; and then studying the variability by using such models as paper folding, joint and member bar. Moreover, we conduct the interactive technology test to simulate the interaction process by the means of physical information input and virtual animation output. Finally, we choose one kind of lightweight solar panel with proper specification which meets the research requirements to match the design. 4) Design experiment: integrating the above data, observing the daylighting advantage of the vacant urban spaces, and regarding the overpass as the design object to analyze its space, sunshine, events, etc. we apply a human-oriented design and re-define another nature for the overpass in the city.

According to above analysis, we choose the Landscape Bridge of Zhonghua Road as the base, to analyze the current condition, sunshine and space planning of the bridge. Besides, we place the urban prothallus on the upper side of the bridge as the skin to absorb light, and adjust the phototropic angle through the interactive technology to reach the state that bionic phototropism could follow the light. Moreover, we apply the converted light energy supply as the spatial demand in the base, and also add some new events to activate the old functions of the overpass. Through the design operation, the prototype is expected that more unused spaces can be used as the operation objects of renewable energy sources, so as to provide a new possibility for the urban spatial demands.
