Estimates based on 5th World's validated data from PSGH projects across Kamloops, BC, Calgary, AB, London, ON, and Boulder, CO. Actual yields, costs, and energy performance vary based on site conditions, construction quality, local energy prices, and growing practices. This is a planning tool — not a design specification.
