日本 Renai House 災難後的永續住屋

Hello, this is Tim again.

I hope you enjoy the tour at the Orchid house last time, which is designed by the team from our homeland Taiwan. Today I’m going to take you guys around in the Solar Village, and discover more about green housing.


In addition of sustainability and energy efficiency, each team also has to confront their own social problems. Among all the teams that participate in SDE 2014, there was one that caught my attention first, it was the Japanese team, who try to find new solutions for emergency housing.

除了永續性與能源效率,每個隊伍也需要正面去解決各自的社會問題。在參加2014年太陽能建築十項全能綠色競賽的所有隊伍之中,最先吸引我注意的是日本隊,他們嘗試為急難時的臨時住屋 (emergency housing) 找出新的對策。

The reason that I get interested in this team is that our country, Taiwan, should also think about the same question. Taiwan as well as Japan, are all located in earthquake zones; aside from earthquakes, we also got monsoons and typhoons that bring us quite a lot of troubles each year. We should be learning, and also thinking about faster and more efficient ways to help our victims after catastrophes.


Now let’s look at Japan’s plan first. Experiencing the tsunami that struck three years ago, the architectural team from Chiba University (千葉大學) started brainstorming about the emergency housing problem. After the disaster, the victims usually need immediate support, but the temporary shelters needs time to be transported, not to mention the condition of the place. Furthermore, the victims need not only physical healing, mental rebuilding is needed too. Is it possible to build an emergency shelter with speed, flexibility and dignity?


Yes, “Speed”, “Flexibility”, “Dignity” is the three goals Chiba University set for their project – Renai House. The Renai House has a simple, gray box-like outlook, I agree that it doesn’t look that exciting, but a shape like this creates perfect size for truck or ship transportation. There is no need to break the house into tiny pieces, and the whole structure can be assembled just in a flash by combining a few “bricks” together. The Renai House is also going to be manufactured in nearby factories. All these planning will made up the “Speed”.

「速度」、「彈性」與「尊嚴」,是千葉大學為他們作品「Renai House」設立的三個目標。Renai House看來就像個簡單的灰色箱子,我承認看起來並不讓人驚喜,但這個房屋的形狀大小其實恰好符合貨車與船舶運輸,不需要拆裝,且可快速地將幾個「磚頭」組合成一個大結構,因此可以在附近工廠組裝,達到快速的目的。

About the second goal “Flexibility”. The core of the Renai House “Urban Seed”, is the piece that contains all plumbing, wiring, and basic home appliances, by adding more or less other parts on, the Renai House can be designed as the habitats preference, or even offices, clinics, schools ext. The “Lego style” design leaves the usage of the structure to your creativity.

「Renai House」的核心叫做「都市種子 Urban Seed」,單一個方塊即包含水管、電線與基本的家用電器;只要將或多或少的種子組合起來,便可為不同所在地而適地設計,甚至可成為辦公室、診所或學校等。「樂高式」的設計容許使用者依照功能,以創意來改變結構。這便是第二目標的「彈性」。

“Dignity” might be a little bit hard to explain. After the disaster, the plan is to plant in the Urban Seeds in priority, it will be a sharing shelter and kitchen that helps rebuild the victims hope and the community. Then it grows and flourish into private houses or others, lastly forming a new city. This process grows the house itself, and grows the victims confident at the same time, and I guess that’s the reason for calling it “Dignity”.

The power for the Renai House is generated by the PV panels on top of the Urban Seed, and the extra power will be stored in the batteries, being used for car charging. They actually parked a car next to the Renai House to charge. The other kind of thermal panels are the one that water runs through, the liquid gets heated by this process. These are the energy strategy of the house.

Renai House的用電來源,來自於都市種子頂上的太陽能光電板,多出來的電力則儲存在電池,用來為汽車充電,汽車就停在房子旁。另外也安裝太陽熱能熱水系統。這兩者就是房子的能源策略。

Also, by designing the structure to be highly insulate, and using natural wood as the material, the Renai House can perfectly maintain the indoor temperature and other conditions. Comparing to normal houses in Japan, it sharply cuts down the energy consumption by 80%. That’s a astonishing energy efficiency!

此外,由於採取高度隔熱設計,並使用天然木材為建材,Renai House能妥善保持室內溫度與環境條件。與日本的一般房屋相比,它能大幅削減能源耗用80%,這是一個相當可觀的節能效率!

The interior of the Renai House has a Japanese style, which is quite simple but cozy. The inner space includes a kitchen, a bathroom, a free using room, and the bedroom, living room and dining area are three in one. It isn’t a complicated design, which is pretty much suitable and comfortable for victims.

Renai House的室內裝潢則是日本家居風格,簡單舒適,包括廚房、浴室,與一個自由使用的空間,臥室與客廳、餐廳則是三者合一。設計並不複雜,對於受災戶而言非常適合與舒適。

That’s how the Renai House is, what do you think about it? An emergency shelter should be fast to build, but the comfort should be considered equally, because what the victims need is not only a place for living, but they also need a place for their heart and future. Taiwan should think these over. Here I’m hoping that someday Taiwan could realize that housing could also be a strategy to give hope to others.

以上是Renai House的介紹,各位覺得如何?緊急避難所應該要快速建立,但同樣要考慮舒適性,畢竟受災戶需要的不僅是棲身之所,同時也需要一個心理與未來可以安定下來的地方。台灣也該想到這些。我希望有天台灣能了解,提供住屋,也會是給予他人「希望」的一種方式。
