綠核藍天能源屋 扭轉您對鐵皮屋頂的想像

"太陽能建築十項全能綠色競賽正在巴黎凡爾賽宮舉辦,台灣交大建築所學生以頂樓住宅為原型所設計的「蘭花屋」已經搭建完成,新竹中學的彥廷也加入他們,為遊客解說這棟特別的計畫,來聽聽看他怎麼為我們導覽!"


文/陳彥廷 (台達能源教育青年大使,新竹高中)

Hello, my name is Tim, and I’m going to give you a tour of the Orchid House today.

哈囉,我是彥廷,今日將由我為各位導覽這棟「蘭花屋」。

The Orchid House designed by the students of National Chiao Tung University from Taiwan, is an urban dwelling. Taiwan, as all of you might know, is an small island located in south east Asia, the climate is pretty hot and humid, and it rains a lot during the typhoon and monsoon seasons. Also, our population density is extremely high, our island is slightly larger than Belgium, put our population is even higher than Australia’s, and most of the citizens have lived in cities.

蘭花屋是由台灣國立交通大學的學生所設計,是要作為一棟都市住宅。各位應該知道,台灣是個位處東南亞的小島,氣候相當濕熱,颱風與梅雨季節降雨甚多。同時,人口密度相當高,較比利時稍大的土地面積上,擺上略多於澳洲的人口,而大多數的民眾是居住在城市裡。

Due to the terrible high urban density, people build up metal sheet cabins on our rooftops, in order to gain extra living space. However, the cabin has its problems. The metal structure locks all the heat indoors during summer, making the inside even hotter than the outside; most people switch on their air-conditioner to cool the house down, but that’s not sustainable at all. Also, it might leak when it rains, because of bad construction, and it’s too weak to stand the storms; not to mention that it is illegal.

也因為城市人口密度高的可怕,民眾會在頂樓上方加蓋鐵皮屋,爭取額外的生活空間。然而,鐵皮屋仍有些問題。夏季中,鐵皮屋的金屬結構會把熱氣鎖在室內,使得室內竟然比室外熱。大多數人打開冷氣來降溫,但這一點都不永續。並且,鐵皮屋在下雨時,可能會因為施工不嚴謹而滲水,或難以抵禦暴風;更別說會有違法之虞。

As you can see, the cabin is not a really good choice for living, but because of the rising price of urban houses, these are probably the only housings that the younger generations can afford. That’s why we come up with the plan of the Orchid House.

您可以了解,儘管並不是很好的居住選擇,但由於市區房價高漲,比較年輕的一代可能也只能負擔的起頂樓鐵皮屋。這也是為何我們提出「蘭花屋」這個建築計畫。

Why Orchid House? As you might ask. It has three reasons. First, Taiwan is the second largest exporter of orchids. Second, orchids represent elegance, and that’s how we want the lives in there to be. Third, the house took the living strategy of orchids, which flourish on high treetops and absorbs non-direct sunlight and running off rainwater. You’ll see how the strategies were practiced, later when I introduce the facilities.

您可能會問,為何是「蘭花屋」呢?有三個原因。首先,台灣是第二大的蘭花外銷國;再者,蘭花代表著優雅,如同我們也想在這裡優雅地過生活。第三,這棟房子採行了蘭花的生存法則,在樹木上層繁茂盛開,接收間接灑落的陽光與雨水逕流。待會我介紹屋中設備時,您就可以明瞭我們如何履行這些法則。

Now let’s enter the living area of the house. The first part you see is the kitchen, and now please admire the furniture. Guess what, they are made by prisoners, Taiwan have been encouraging our prisoners to learn new skills, helping them to prepare for their future life.

現在,讓我們進入房子的起居空間,你看到的第一部分是廚房,請看看這些家具,這是由監獄受刑人所製作的。台灣一直鼓勵受刑人學習新技能,幫助他們為再生生涯預先準備。

You might notice the wall behind. It’s called the thermal mass, which are basically bottles filled with water, it traps the energy from the sun and blocks the heat outdoor in the day, so it could be cool indoor. Later it releases the heat at night, so it warms up the house in cold nights. All the bottles on the wall are 100% recycled, so they’re perfectly sustainable.

您可能注意到身後的這片牆。這就是所謂的Thermal Mass (蓄熱牆,蓄積熱質量的建築外殼建材),基本上就是寶特瓶裝滿水,用來捕獲來自太陽的能量,也阻擋了白天戶外的炎熱,讓室內保持涼爽。晚上它會釋放出熱氣,在寒冷的夜裡溫暖房屋。牆上這批瓶子都是100%回收再利用,所以相當永續。

Over here is a computer, it is connected all the systems and sensors, and shows and controls all the conditions of your living place automatically. It is such a smart brain isn’t it? With this we could make sure the all the water and energy is used efficiently.

屋內這台電腦,連接所有系統和感應器,可顯示並自動控制起居空間內的所有環境條件。不就像是裝了顆聰明的大腦嗎?有了這個,我們可以確保用水和能源都能夠用的更有效率。

The following part is my favorite of the Orchid House. Welcome to the tea terrace! This is where the habitats could chat, play chess or enjoy their tea . What you see next to it is the lungs of Orchid House – the green core. It’s a wall filled with a variety of vegetation, including orchids, we uses this to clean up and cool down the air interior, while it also displays the biodiversity in the forests of Taiwan. There’s a interesting information about the plants here, most plants absorbs the most carbon dioxide in day, but orchids are opposite. So the temperature could be balanced either in the day or at night.

接下來是我最喜歡的區域,歡迎來到飲茶室!這裡是房客能夠聊天,下棋或品茶的所在。旁邊則是蘭花屋的肺 ─ 綠核。這是一片擁有多種植物的植生牆,蘭花即是其中一種。我們以綠核清潔與冷卻室內空氣,其實這也展現著台灣森林的生物多樣性。這裡有個關於植物的有趣資訊,大多植物會在白天吸收較多的二氧化碳,但蘭花反而在夜間吸收較多二氧化碳。因此,不管在白天或夜晚,室內溫度可以調節平衡。

Now if you look above your head, there are some “cells” on our roof right? Those are the invention of our students, named “Smart-skin”. A smart-skin is triggered by a piece of spring that shrinks or expands according to the heat from sunlight. The size of the hole in the middle changes, so that the amount of direct sunlight coming in could be controlled.

請看一下頭上的天花板,是不是有些「細胞」?這些是建築研究所的學生發明,是一種建築「智慧皮層」(Smart-skin)。智慧皮層是由一片彈簧啟動,而彈簧的開闔是依據陽光帶來的熱氣,中間孔洞的大小也因而改變,控制著直射屋內的陽光多寡。

So before we leave, I want to summarize this project in three keywords: Green Core, which represents how we want to make the city more sustainable; Blue Sky, which refers to our plan of getting rid of the bad impression on illegal sheet-metal structures and cleaning the city skyline; and Power House, which not only refers to the capture of solar energy, but also represents our hopes that our House will be the gamechanger in the future of Taiwan.

在離開蘭花屋之前,我想總結三個關鍵字:「綠核」(Green Core),顯示出我們如何讓城市更加永續;「藍天」(Blue Sky),這裡說的是我們計畫擺脫非法鐵皮屋,的壞印象,革新天際線;「能源屋」(Power House),不僅指的是捕捉陽光作為能源,也代表著這棟蘭花屋將能在未來的台灣,扭轉遊戲規則。

This is all about the Orchid House. I wish this project has remind you that what environmentally friendly and sustainability are; and I hope that it inspires you that they could actually be easily practiced in daily life. Everyone of you could be the game changer of our world, and I will look forward to that.

以上就是蘭花屋的介紹,我希望這個太陽能建築計畫能提醒您,甚麼是對環境友善的,甚麼的永續的;我也希望可以帶給您一些啟發,這些綠色策略能易於在日常生活中實行。您們每個人都可能扭轉我們世界的遊戲規則,我非常期待。
