탄소 없는 미래를 위한 선언을 구현한 타이완 창화현의 선록

태양광을 효과적으로 유입하기 위한 유기적인 입면, 에너지 효율성과 잠재성을 높여주는 에너지 자립형 건물로 손색이 없어

타이완 창화현의 선록은 대만전력공사(Taipower) 유지보수 작업장과 사무실, 창고 등의 운영시설로 계획되었다.

MVRDV가 디자인한 건물의 유기적인 외관은 효율적인 태양 에너지를 생산하는 곳으로 ‘탄소 없는 미래를 위한 선언’을 효과적으로 담아내고 있다.

건물은 대만 서부의 도시인 타이중 근처의 창화해안공업단지에 위치하며 지속 가능한 에너지 장비를 보관하고 유지관리를 위한 시설이다. 빼곡한 태양광 패널로 둘러싸인 외관에서 잘 드러나듯 선록의 둥근 모양은 태양 에너지를 최대한 흡수할 수 있도록 계획되었다.

완만하게 아래쪽으로 기울어져 있는 남측 입면은 한낮의 태양을 직접 마주하는 넓은 표면적을 만들어준다. 돔 형태의 북측 입면은 아침과 저녁에 햇볕에 노출되며 건물의 면적을 극대화한다. 정면은 상부 표면에 태양광 패널을 지지하는 주름의 각도를 통해 태양 전지판의 에너지 잠재력을 최대화시킨다. 이러한 최소 4,000㎡의 PV패널을 통해 건물은 연간 100만kWh의 청정에너지를 생성할 수 있게 된다. 이는 원유 85톤을 소비할 수 있는 양으로 완전히 에너지 자립형 건물인 셈이다.

MVRDV의 창립 파트너인 위니 마스는 “데이터 중심성을 근간으로 PV패널을 최대한 효율적으로 배치함으로써 건물 전체를 광전지로 덮고 에너지 이득을 극대화함으로써 지속가능한 디자인을 구현하고자 했다”고 밝혔다. 건물의 중심 아트리움에는 대만전력공사가 운영하는 재생가능한 에너지의 양이 실시간으로 표시되는 데이터룸이 마련되어 있다. 1층의 갤러리 공간에서는 유지보수 작업장을 볼 수 있다. 태양 전지판에서 거대한 풍력 터빈 블레이드에 이르기까지 지속 가능한 에너지를 가능하게 하는 기계장치를 가까이서 감상할 수 있어 공간의 즐거움을 더해준다. 옥상에는 태양열 패널 돔 아래 나무 테라스가 마련되어 있어 직원들의 쉼터 역할을 맡는다.

선록의 지속가능한 에너지 생성 기능은 실용적인 디자인과 결합하여 대만전력공사의 친환경적인 미래 계획을 효과적으로 보여줄 수 있는 중요한 커뮤니케이션 공간이 된다. ANN

MVRDV’s “Sun Rock” is a built manifesto for Taipower’s carbon-free future

MVRDV has revealed Sun Rock, an operations facility containing offices, a maintenance workshop, storage spaces, and a public gallery for Taiwan’s government-owned power company Taipower.

Anticipating Taiwan’s planned transition to green energy, the features of the Sun Rock building, from its shape to its facade, are focused upon generating solar energy as efficiently as possible. The building therefore acts as a definitive statement of intention, and a “manifesto in a building” to communicate Taipower’s goals to the public.

Located at the Changhua Coastal Industrial Park, near to Taichung, the building’s primary purpose is for the storage and maintenance of sustainable energy equipment. The site for Taipower’s new facility receives a significant amount of solar exposure throughout the year, and so the rounded shape of Sun Rock is designed to maximise how much of that sunlight can be harnessed for energy.

On the southern side, the building slopes gently downwards, creating a large surface area that directly faces the sun during the middle of the day. At the northern end, the domed shape maximises the area of the building exposed to the sun in the mornings and evenings.

The facade maximises this solar potential with a series of pleats, which support photovoltaic panels (mixed in with windows, where required) on their upper surface. The angle of these pleats is adjusted on all parts of the facade to maximise the energy-generating potential of the solar panels.

As a result of these measures, the building can support at least 4,000 square metres of PV panels that would generate almost 1 million kilowatt-hours of clean energy per year - an amount of energy equivalent to burning 85 tonnes of crude oil - and making the building completely self-sufficient.

Further design options are under consideration that would add an even larger area of PV panels, with calculations showing the building could generate up to 1.7 million kWh annually to contribute energy to the grid.

“Of course, we aim to make all of our projects as sustainable as possible. Yet we see that projects can go beyond just being sustainable in themselves. This project has unique and fascinating potential”, says MVRDV founding partner Winy Maas. “The user is an energy company, which has allowed us to do more than usual. We cladded the entire facade with photovoltaics, maximising the energy gains to make it not only self-sustainable, for its own usage, but also allowing the building to become a tool of energy production, exporting electricity to the rest of the grid. This is achieved through a maximally efficient positioning of the panels. As a result, our design is completely data-driven. It’s always fun to see the results when you let analysis be the determining part of the design.”

At the heart of the building is the Data Room, a soaring atrium with real-time displays of data about Taipower’s operations and the amount of renewable energy the company generates. On the first floor, a gallery space provides a view onto the maintenance workshop, allowing the public an upclose look at the machines that make sustainable energy possible, from solar panels to massive wind turbine blades. A further gallery for exhibitions is included on the top floor, while at roof level, under the shelter of a dome of solar panels, is a terrace complete with trees for both visitors and Taipower employees to relax.

The sustainable energy-generating features of Sun Rock make the building more than simply an operations and maintenance facility; the design cleverly combines the building’s utilitarian spaces

with a series of gallery spaces. The building is thus also an important communication tool for Taipower to publicly show their ambitions for a greener future.
