Situated adjacent to the Estimauville eco-neighbourhood, STGM’s new head office puts the focus on eco-friendly, architectural innovation.The building succeeds in offering an exceptional level of comfort to its occupants. The designers (STGM architectes and the interior design studio IDEA)used ingenious strategies to reach LEED-NC Platinum level, the highest in the internationally recognized LEED® green building certification system On one hand, the characteristics of the site itself dictated the approach to the structural concept.The limited bearing capacity of the ground was limited, so a lightweight ductile wood frame with a low ecological footprint proved to be the best solution. The building’s longitudinal form, developed on a north-south axis, allows for abundant natural lighting. A strategically positioned series of windows vents open on the side, providing natural cross ventilation. Salvaged and recycled materials without volatile organic compounds (VOCs) were integrated into the project, and regional provenance (local sourcing) was prioritized throughout the process. In making their selection, the jury noted the harmony between the exterior and interior treatment. They also appreciated the overall integration of the design, which, in addition to being LEED certified, provided for the comfort of the building’s occupants, setting this project apart from the competition.
