Designing energy-efficient buildings in cold climates presents a unique challenge. Long winters, high heating demands, and the need for durable materials can make it difficult to reduce energy use while maintaining comfort, air quality, and accessibility in public spaces.
The Okâch – Îyethkabi Oûgitûbi pavilion in Banff addresses this challenge through a high-performance, all-electric design built to Passive House standards. The project uses mass timber construction, advanced insulation, and airtight building systems to reduce heat loss, while incorporating a rooftop solar array and energy-efficient mechanical systems. Designed for year-round use, the space provides accessible amenities for residents and visitors in one of Canada’s most demanding climates.
The building is designed to operate at net-zero emissions, generates approximately 19,000 kWh of renewable energy annually, and sequesters around 100 tonnes of carbon while delivering a durable, accessible community space built to last over 100 years.
