Context

Saskatchewan's carbon-intensive electrical grid presents a significant operational emissions challenge — building operations in the province can produce up to 700% more CO₂e than equivalent buildings in Canada’s provinces such as Ontario, where hydroelectric and nuclear power dominate the grid. The Muscowpetung Powwow Arbour delivers an unconditioned cultural building that looks at passive strategies for achieving thermal comfort for the three seasons (spring, summer, fall) where land-based cultural activities take place. The resultant climate responsive design, guided by traditional Saulteaux knowledge and resource stewardship practices, shifts it’s focus entirely to embodied carbon reduction and regenerative landscape strategies to achieve carbon neutrality within a 5 year period.

Whole Life Cycle Assessment

A whole life cycle assessment (WLCA) governed material selection and structural assembly decisions throughout the design process.

• Timber vs. steel comparison: heavy timber with biogenic carbon storage demonstrated a 68% reduction in CO₂e relative to a structural steel alternative.

• Substitution of structural round timber (SRT) for engineered glulam reduced embodied carbon by an additional 20% per structural member.

• SRT requires minimal processing, maintains continuous wood fibre orientation, and shortens the supply chain by eliminating outsourcing, thus reducing transport and manufacturing emissions.

• Tripod column geometry enables structural stability with smaller-diameter round timbers, avoiding the harvesting of larger trees required for dimensional milled lumber.

Landscape & Carbon Sequestration

• The 6.2-hectare site is to be converted from conventional agriculture to native perennial prairie vegetation.

• Annual sequestration: estimated 12.3 tonnes CO₂e/year.

• Emissions avoided through cessation of intensive cropping practices: 10.5 tonnes CO₂e/year.

• Combined sequestration and avoidance: the project is on track to achieve carbon neutrality by 2031.

Integrated Design Strategy

The circular structural form supports both cultural significance and technical efficiency. The conical roof, open at the oculus, admits daylight to the dance area below, sustaining shade-tolerant ground cover and eliminating the need for artificial lighting during use. Landscape and structure are treated as a single integrated system.

Outcome

The Muscowpetung Powwow Arbour demonstrates that design rooted in traditional Indigenous knowledge can produce measurable, quantifiable climate outcomes. The project is classified as a regenerative development, sequestering more carbon than it produces over its lifecycle while restoring ecological benefits to the land.
