Passive design: comfort, efficiency, & resilience
We bring Passive House principles to our projects with a deep understanding of space, light, and material to create ultra-energy-efficient homes and buildings that are comfortable and durable. Certified projects undergo third-party technical inspection to further verify energy and design performance. Tailored for Ontario's climate, our all-electric, low-impact spaces balance performance, comfort, and aesthetic appeal.
Considering a home designed for comfort, efficiency, and longevity? Planning renovations or upgrades to create more thoughtful, high-performing spaces?
Let’s talk.

Passive design principles
Integrated process
Passive design integrates performance at every stage, aligning airtightness, insulation, and mechanical systems with the architectural vision for refined, high-performance buildings.
Thermal comfort
Super-insulated, airtight construction with passive heating and cooling creates stable indoor environments that stay comfortable year-round with minimal mechanical intervention. And yes, windows can be opened anytime!
Energy efficiency
Passive House buildings cut heating and cooling energy use by up to 90%, using fresh air systems, thermal bridge-free construction, and ultra-low-energy strategies to reduce environmental impact.
Daylighting optimization
Through strategic window placement, shading, and high-performance glazing, we design spaces where daylight becomes a defining feature, reducing artificial lighting needs and enhancing livability.
Material performance
We prioritize durable, low-carbon materials that enhance building performance and resilience, from high-performance insulation to responsibly sourced finishes.
Site & building connection
Effective site planning enhances building durability, comfort, and energy efficiency. Our designs optimize daylight, air circulation, and environmental integration to create sustainable, resilient spaces for both new builds and retrofits.
Frequently asked questions
-
A certified Passive House can reduce heating and cooling energy by up to 90%, thanks to airtight construction, high insulation, and efficient mechanical systems.
-
Yes, Passive House construction has higher upfront costs for insulation, materials, and labor but offers long-term savings through lower energy bills and maintenance. Smaller, simpler mechanical systems reduce complexity and free up space. High-performance components are also becoming more affordable as the market evolves.
-
Yes! Passive Houses are designed for comfort with or without open windows. The heat recovery ventilation system maintains air quality even when windows remain closed.
-
Not necessarily. Passive House is a performance standard, not an aesthetic style. It can be designed in any architectural style, from contemporary to traditional. The primary differences lie in the construction techniques—with better insulation, airtight construction, high-performance windows, and carefully considered ventilation systems—all designed to optimize comfort, energy efficiency, and durability.
