芬蘭赫爾辛基 Vuosaari 生質能供熱廠
坐落於東赫爾辛基港區，Vuosaari 生質能供熱廠是 Helen 能源公司邁向 2030 碳中和目標的重要基地，亦是 Kivinen Rusanen Architects 十年來深耕規劃的成果。新廠以 260 MW 容量供應全市四分之一的區域供熱，每年減碳約七十萬噸，展現高度能源效率與技術潛能。
The Vuosaari Bioenergy Heating Plant is the latest addition to the Vuosaari power plant site in Eastern Helsinki. Owned by the local Helen Ltd utility, the facility has produced much of Helsinki's power and district heat since the 1980s. The new heating plant is part of Helen's push for carbon neutrality by 2030. The 260 MW bioenergy heating plant produces about a quarter of Helsinki's district heat, and reduces the city's carbon dioxide emissions by around 700,000 tonnes annually. The Vuosaari Bioenergy Heating Plant is an exceptionally energy-efficient combustion plant, with 122% efficiency. Although it does not produce electricity, converting it to combined heat and power production is technically feasible.
全新建築由芬蘭 Kivinen Rusanen Architects 設計，延續其十餘年來於 Vuosaari 園區內的系列規劃與設計工作。從早期的能源系統規模評估，到今日的綠色能源落地，每一階段的發展均見證著 Helen 對永續發電模式的投入。而園區內所有建築體，也皆出自該建築事務所之手。
The bioenergy heating plant is the latest to be designed by Kivinen Rusanen Architects at Helen's Vuosaari site. It follows a planning period of more than ten years, during which different options for developing the power plant complex were studied in terms of technology and scale. Electricity and district heat production in Vuosaari started in the 1980s and has been continuously developed and expanded. From the outset, Kivinen Rusanen Architects has designed all of the buildings on the power plant site.
新廠由兩大部分組成：一為高聳修長的鍋爐主體建築，另一為生質燃料處理系統。鍋爐建築內設有高效的餘熱回收系統，其量體輪廓順應內部設備的高度層層堆疊，展現清晰的機能邏輯。燃料處理系統則包含接收、篩選與儲存等設施，並透過緊湊排列的輸送帶系統串聯各處。整體基地配置以物流效率、工藝流程與操作安全為優先考量，建築與設備體量經精密規劃後，留有未來擴建彈性與通行空間。例如燃料輸送帶採用截面精巧的鋼構桁架結構，降低佔地面積，同時確保機能與結構強度。
The plant has two main parts: a tall, long boiler building, and a biofuel handling system. The boiler building houses the boiler and an advanced heat recovery system. Its staggered volume follows the heights of the different process equipment inside. The fuel handling part comprises buildings for receiving, screening, and storing the biomass fuel, together with a system of conveyors. The site layout prioritises logistics, process flow, and safety. Compact solutions in the arrangement and sizes of the buildings and equipment on the site were sought to leave room for future projects and logistical freedom. This can be seen in how close the new facility is to the existing plant, and how the fuel handling system uses technology that allows the different parts to be placed in a tight formation. Also, the legs of the long main conveyor are steel trusses with a compact square cross-section, minimising their footprint.
位於 Vuosaari 港灣可見度極高的位置，設計團隊特別考量其從北側公園、遠方住宅區與海上視角的觀感，同時兼顧 Satamakaari 街道與鄰近電廠設施的近距離視覺經驗。為此，建築語彙以高品質的設計與施工完成度為前提，使建築形象與其所處環境相得益彰。
The project is a highly visible part of the Vuosaari harbour landscape. Its design sought to consider the plant's visibility from the new park on the Northern side of the power plant site, residential areas further away to the West, and views from the sea. On the other hand, the close views from Satamakaari Street, and the existing power plant facilities, were essential. The architectural objective was to ensure a high-quality design, construction, and finish so that the completed project would reflect its visibility in its surroundings.
量體由場域邊緣向核心逐步遞增：高聳的鍋爐建築位於基地中央，而低矮的燃料處理設施則配置於西側、臨近車流與人行路段。街道側高聳的土坡亦經綠化美化，有效柔化工業氛圍，提升街景親和力。視覺表現上，採中性色調與抽象語彙，營造永續、恆久的視覺印象；外牆選用雙層立面系統，不僅整合視覺一致性，亦隱藏外露管線與設備，實現機能與美學的平衡。鍋爐與燃料接收建築配置大面積帷幕玻璃，引入自然光線，提升內部舒適度與安全性，特別是在緊急狀況下，能提供照明系統的備援支援。
The scale of the new buildings increases from the periphery to the centre of the plot. The tall boiler building is in the centre of the site, while the lower fuel handling buildings are on the western side, close to passing traffic and people. This is reinforced by the extensive landscaping of the high and steep embankment along Satamakaari Street, enhancing the street-level experience and softening the industrial character of the plant site.
兩種不同的雙層立面材質運用於本案中：鍋爐建築採用大面鋁複合板，具備輕量、高強度與符合防火規範等特性；燃料處理建築則使用波浪狀壓型鋼板，因應其建築量體的複雜性與靈活性需求。部分外牆設計為穿孔板，於特定位置引入光線與氣流。此外，建築亦以預鑄與現場澆築的黑白清水混凝土結構，對比雙層金屬立面，展現材料層次與結構張力。
The fuel handling system consists of a more complex array of buildings and structures. Profiled sheet steel was chosen as the cladding material for these buildings, as the dimensions and characteristics of the material make it a more flexible cladding solution. Both types of cladding are partially perforated at points where light or air passes through the entire façade structure. High-quality massive structures in pre-fabricated and in-situ black or white concrete are used in contrast to the lightweight steel double façades and metal claddings.
Vuosaari 生質能供熱廠除了是城市基礎設施的一環，更以建築語言展現其在永續轉型中的關鍵角色，為城市帶來穩定綠能的同時，也體現公共設施應有的尊嚴與價值。
Operationally, the Vuosaari Bioenergy Heating Plant meets one of the vital basic needs by providing the city with sustainable district heating. Its architecture aims to convey the value and importance of this activity.
