Project Description

Wild Leek Farm has been designed with Passive House, Permaculture, and local sourcing principles in mind.  It resembles a classic North American farmhouse aesthetically, but has modern finishes and efficiencies which bear no resemblance to farmhouses of yesteryear.

The project team includes Graham Whiting of Whitefish Architecture as designer and energy modeller; Local Impact Design as architect and mechanical designer; Evolve Builders Group Inc as builder; Blue-Green Group as verifier.

Wild Leek Farm achieved Passive House levels of performance while keeping the forms and details as streamlined possible, making it more affordable to build and allowing for owner participation on the build.  The team used construction materials with low toxicity;  sustainable, efficient, and local products, i.e., the triple-glazed doors and windows and recycled-content drywall were all made in Canada.

Modeled energy consumption averaged 2,400 kWh per month. Actual consumption so far has been from 800 to 1,200 kWh.


Heating demand 118.5 kWh/m2a

Cooling and dehumidification demand 110 kWh/m2a Primary energy demand 107 kWh/m²a Air leakage 110.55 A
