漂浮在加拿大草原上的圓形結構,Oxbow 與 Richard Kroeker 為薩爾托社區打造文化中心
漂浮在加拿大草原上的圓形木結構,Oxbow 與 Richard Kroeker 為薩爾托原住民族打造文化中心
.
位於加拿大薩斯喀徹溫省的「Muscowpetung Powwow Arbour」,是由 Oxbow Architecture 與建築師 Richard Kroeker 共同設計的文化地標;這座圓形露天涼亭是當地夏季慶典的重心,也嶄露了薩爾托 (Saulteaux) 原住民族的文化精神與對圓形的崇敬。
.
透過與部落長老及當地知識傳承者 Jeff Cappo 的深入諮詢,建築設計勾勒出傳統帳篷的意象,並呈現宛如漂浮於大草原地平線上的輕盈感。
.
佔地 1,275 平方公尺的 Arbour 空間足以容納 2,500 名觀眾與 1,000 名舞者,建築團隊秉持「Mino-pimatisiwin」(美好生活)的薩爾托概念,致力於氣候行動,且積極促進社區福祉與知識傳承。
.
為了達到控制成本的目標,建築工程優先聘用在地勞動力,並盡可能採用區域性的圓木建材,實踐了傳統智慧與現代永續建築的結合。
.
圓木結構 (SRT,Structural Round Timber) 的應用:相較於結構鋼材,實木儲存了生物源碳,排放量減少 68%;若將膠合木換為結構圓木,更能額外減少 20% 的隱含碳;減少了加工工序,縮短供應鏈,同時透過三腳架柱幾何結構,以較小徑的圓木達到優異的穩定性,無需砍伐巨型樹木。
.
氣候適應與被動式設計:有別於薩斯喀徹溫省依賴的高碳電網,本案採取被動式設計,在春夏秋三季利用結構遮陽與自然通風達成熱舒適,不僅解決了當地高營運排放的挑戰,更實現了建築的靈活性。
.
生態與負碳規劃:基地周邊的 6.2 公頃傳統農地將轉型為原生草原,每年預計能封存 12.3 噸二氧化碳,並透過停止集約農耕可減少排放 10.5 噸。這項再生設計預計於 2031 年實現碳中和,甚至邁向負碳目標。
.
涼亭中央的「天空視窗」(Oculus) 是全案的靈魂,它不僅引進陽光照亮下方的舞者區域,更為該處喜蔭植物提供了養分。
Muscowpetung Powwow Arbour 不僅證明了原住民傳統知識能產生可量化的氣候成果,更是一座連結土地、文化與未來的再生地標。

這座位於加拿大草原上的涼亭「Muscowpetung Powwow Arbour」,簡直是建築與文化共生的典範!
Oxbow Architecture 與 Richard Kroeker 設計的這棟建築,靈感來自薩爾托民族的圓形文化,巨大的圓錐形屋頂中央開了一個「天空之眼」,讓陽光灑落,照亮下方的舞者與綠色植被。
最厲害的是它的「負碳」設計:
1. **就地取材**:使用結構圓木取代鋼材,減少了 68% 的碳排放,還不需要砍伐大樹。
2. **負碳開發**:把荒廢的農地種回原生草地,吸收的碳遠超過建築產生的碳,預計 2031 年就能達成碳中和。
3. **文化與氣候共融**:不開暖氣,全靠結構設計達成四季的舒適感。
這棟建築不僅支持了原住民文化的傳承,還實打實地解決了氣候變遷問題。這就是建築師說的「美好生活」(Mino-pimatisiwin),把傳統智慧用最現代、最溫柔的方式實踐出來。
The vibrant cultural center, designed by Oxbow Architecture and Richard Kroeker, is conceived as the centerpiece of the summer powwow celebrations. The structure draws inspiration from the material culture of Saulteaux and the symbolic importance of the circle. Its open, circular form, the result of extensive consultation with community elders, evokes traditional huts while creating a light roof that appears to float on the prairie horizon.
The project aims to strengthen traditions, celebrate culture, and encourage community members to pass on their knowledge to future generations. The building's design was established through consultations with the community and tribal leaders, particularly local knowledge keeper Jeff Cappo. The completed gazebo covers 1,275 square meters and can accommodate 2,500 spectators and 1,000 dancers.

Architecture with Social Impact
The project supports the community's economic goals by involving local labor in the construction process, with building approaches strategically aligned with local resources and skills. The Arbour, a regenerative project in every sense, reflects the Mino-pimatisiwin concept of saulteaux—"living well"—and directly addresses both the climate crisis and the needs of the Muscowpetung community.
Built with regionally sourced round timber and local labor, the Arbour reflects traditional knowledge through sustainable and resource-efficient construction. Its conical roof, open at the center, allows light to enter and nourish the vegetation, seamlessly integrating landscape and architecture.
Beyond its architectural significance, the Arbour serves as a cultural center that promotes family well-being, education, and community life. Surrounded by restored native grasslands, the project demonstrates a regenerative design, with ecological restoration and carbon capture that contribute to carbon neutrality and strengthen cultural continuity for future generations.

Context
Saskatchewan’s high-carbon-intensity electricity grid presents a significant operational emissions challenge: building operations in the province can generate up to 700% more CO₂e than similar buildings in Canadian provinces like Ontario, where hydroelectric and nuclear power predominate. The Muscowpetung Powwow Arbour offers an unheated cultural building that employs passive strategies to achieve thermal comfort during the three seasons (spring, summer, and fall) in which outdoor cultural activities take place. The resulting climate-adapted design, guided by Saulteaux’s traditional knowledge and resource management practices, focuses entirely on reducing embodied carbon and employing regenerative landscape strategies to achieve carbon neutrality within five years.

Life Cycle Assessment
A life cycle assessment (LCA) guided material selection and structural assembly decisions throughout the design process.
Comparison between wood and steel: Solid wood with biogenic carbon storage demonstrated a 68% reduction in CO₂e emissions compared to a structural steel alternative.
Replacing glued laminated timber (GL) with structural round timber (SRT) reduced embodied carbon by an additional 20% per structural element.
SRT requires minimal processing, maintains continuous wood fiber orientation, and shortens the supply chain by eliminating subcontracting, thus reducing transportation and manufacturing emissions.
The geometry of the tripod columns allows for structural stability with smaller diameter round timbers, avoiding the felling of larger trees required for dimensional lumber.

Landscape and carbon sequestration
The 6.2-hectare site will be transformed from conventional agriculture to native perennial grassland vegetation.
Annual sequestration: estimated at 12.3 tons of CO₂e/year.
Emissions avoided by ceasing intensive farming practices: 10.5 tons of CO₂e/year.
Combined carbon capture and avoidance: the project is on track to achieve carbon neutrality by 2031.

Integrated design strategy
The circular structural form enhances both cultural significance and technical efficiency. The conical roof, open at the oculus, allows natural light to enter the lower dance area, promoting shade-tolerant vegetation and eliminating the need for artificial lighting during use. The landscape and structure are conceived as an integrated system.
Outcome
The Muscowpetung Powwow Amphitheater demonstrates that a design based on traditional Indigenous knowledge can generate measurable and quantifiable climate outcomes. The project is classified as a regenerative development, as it sequesters more carbon than it produces over its life cycle, while simultaneously restoring the ecological benefits of the land.
