就像動植物一樣,能適應棲地,透過基因不斷演化,以最有效的方式運用能量,維護自身安全,確保物種的代代繁衍。人類也在幾百年來學會順應自然法則,以最有效率的方式搭建屋舍。然而於此同時,我們往往又會迷失自我,忘了如何與大自然共生,以及與大自然共處的情趣。
適應力(構造效能)
這座清水山上的茶亭,坐落於七百公尺高的坡邊,沿用南亞國家已使用數千年的竹子作為建材。竹子大多在一年內就能長到六公尺高,削瘦的竹竿能大幅彎曲,抵禦颱風等級的強風。因此,我們利用彎曲竹身的設計消減風阻,也讓雨水能順勢流到山下。將竹竿縱向剖開後,便可搭建成自然的屋瓦,替茶亭的訪客遮風避雨,抵擋驕陽。所有的竹竿僅以簡單的金屬線材捆綁,因此造價低廉(茶亭的造價約為七千歐元),搭建速度也相當快(總施工時間約為一個月)。
能源效率(永續性)
在台灣,竹子隨處可見、舉手可得,只要一年的時間就能成熟,達到理想的高度與韌度,用來作為建材。傳統上會以煙燻的方式將竹子烘乾,避免白蟻蟲害。這種建材的耐用年限至少為五年以上,因此可說是碳足跡相當低的建材。
整體論(情趣)
這間茶亭最迷人之處,在於與大自然合而為一。善用四周俯拾即是的材料搭建遮風避雨之處,於大自然的懷抱中品茗,沐浴在灑落的陽光下,聆聽風聲、雨聲,以及下方潺潺的河流聲。茶道是家庭日常生活的一部分,卻在茶席之間加深了社交聚會的意義與價值,讓品茗不僅僅止於喝茶。
Mankind has learned over centuries to build very efficiently according to local laws of nature just as plants & animals have themselves Adapted their habitat and genes to maximise their Efficiency in their use of energy, protecting themselves and insuring the flourishing of their species. But also, which has gotten too often lost, we’ve forgotten how to live in symbiosis and Poetry with nature.
Adaptability (Tectonic efficiency)
The Teahouse on Clear Water Mountain sits on the edge of a slope at 700 m altitude. It utilises the Bamboo plant, a building material used in South Asia for thousands of years.
Most Bamboo reaches a height of up to 6 meters within a year. Its slender trunks can bend extremely to withstand very intense speed of wind (Typhoon). It can be bent as we’ve done to minimise resistance to the winds and channel rain down the hillside. It can be cut in half to create a natural roof tiling layer that shelters the teahouse from water and sun. All joints are tied using simple metal strings. That makes it a very cheap material (the tea house having cost 7000 Euro) and one that is quick to erect (overall 1 month construction phase).
Energy efficiency (Sustainability)
Bamboo is readily available and grows in Taiwan to full height within a year. They then will have reached their ideal strength and flexibility to be used as a building material. It is traditionally smoked to dry and resist termites and lasts as a building material for at least 5 years. That makes it a very low carbon footprint building material.
Holism (Poetry)
What excited us about this tea house is working in a Holistic way with nature. Using the materials found around it to create a shelter, celebrating the simplicity of drinking tea and being within nature, the sound of wind, light and sound of the river and rain. Tea ceremonies are an integral part of dBamboo Gazeboaily life within families but also add depth and meaning to social gatherings and there is great value and appreciation for the uniqueness of the herbs being prepared and served. It’s not just consumption.
Buildings are organisms that have a skin to protect, need sun and aeration. Those were carefully considered in the design of the structure and roofing.
The most fascinating evolutionary leap available to us today is our increased understanding of microbiological processes. We can learn very precisely, how species adapt in extreme weather and apply their millennial old ingenuity to architectural surfaces.
There is however first and foremost a need to respect nature. To appreciate its value for our sustainable quality of life and understand its fragility. We need to work with nature, protect it and develop an intertwined trajectory to insure our livelihood.
