Project Overview

BC Passive House (BCPH) Factory began prefabricating its own high-performance building components after successfully assembling Canada’s first Passive House-certified structure, the Lost Lake PassivHaus, which was shipped as a kit of parts from Austria to serve as that country’s hospitality house for the Vancouver 2010 Olympic and Paralympic Winter Games. As demand increased, BCPH began planning a larger factory, one that would provide employees with as high-quality a work environment as they were producing for others. 

Wood Use

The facility includes offices, a showroom, and a high-bay workshop, all contained within a simple rectangular volume. Douglas-fir post-and-beam frames, at six-metre intervals, span from the sides to a central line of columns, forming the main structure. Continuous ledgers on either side of the beams support prefabricated wood-frame roof panels. Exterior twelve-metre cross-laminated timber panels are laid horizontally in a staggered pattern for the walls and are topped with continuous clerestory windows to provide daylight and views in all directions. The showroom and office walls are framed with wood I-joists, super insulated, and certified to Passive House standards. The exterior cladding is of prefabricated panels of horizontal Douglas-fir and dense, durable larch boards.
