Text description provided by the architects. STGM’s new head office is located in the Beauport borough of Quebec City, adjacent to the Estimauville eco-neighbourhood. It is a 1,000 square metre two-storied structure that puts the focus on eco-friendly, architectural innovation. The building succeeds in offering an exceptional level of comfort to its occupants through the mindful integration of a longitudinal form, orientation to the sun, light wood structure, meticulously selected materials and efficient systems, while producing a low ecological footprint.

High performance concrete siding combined with Eastern Cedar creates an impression that is both simple and dynamic, with attention given to the relationship between solids and voidsthat lend the building an air of elegance that belies both time and fashion. From the first sketches, the designers sought to attain a high level of sustainability– a principle already at the heart of the firm’s priorities, using creativity to implement the strategies necessary to reach LEED-NC Platinum level. With this objective in mind, comfort, simplicity and coherence were selected as founding principles.

Environmental performance

STGM’s new offices comprise two vast open-area workshops, closed offices, conference rooms, and indoor and outdoor meeting and rest areas. The longitudinal form, developed north-south, is sober and contemporary. The building integrates innovation and a host of eco-friendly features in view of attaining the highest level of sustainable building certification.

A number of features were included to reduce the consumption of drinking water. Through efficient water management, the building decreases the energy requirements of wastewater treatment plants. The strategies employed aimed to reduce the consumption of drinking water through the use of such water-saving accessories as low-flow faucets and shower heads, and rainwater to flush the toilets.

An ambitious reduction in energy consumption of over 60% compared with the reference building was sought through an innovative aerothermal design and recuperation of the building’s internal heat to curb demand on the distribution networks. A solar wall was also erected on the south-west façade of the building to preheat fresh air. Several control strategies also mitigated at-source needs by adapting lighting, heating and cooling use to actual occupation and needs.

The project designers also focused on the use and management of materials and resources. Tthe building’s ecological signature, for example, is apparent indoors with the use of wood salvaged from old houses in the area. Furniture from the company’s old offices was salvaged and integrated into the new project, without volatile organic compounds (VOCs) and regional provenance (local sourcing) were prioritized throughout the process.

Challenges and solutions

As early as the first sketches, the characteristics of the site itself dictated a minimalist approach to the structural concept. The limited bearing capacity of the ground required minimal structural weight, and so the lightweight ductile wood frame, with a low ecological footprint, proved to be the best solution. With a small percentage of engineered wood and a large portion of lumber, the structure consists of prefabricated small-sized trusses and joists enabling a lighter structure while allowing for wide spans (14 metres) between the posts to create an open work area. The wood roof trusses were integrated as a design element, exposed on the first storey, giving the building its distinctive look.

Positive impacts for users

The building’s location has its benefits for users. The dense sector is located on the outskirts of the downtown core, near a busy highway, with public transportation and a variety of services. Two parking lots are reserved for carpoolers and a charging station for electric cars is at the disposal of employees. The south facing terrace serves as a much appreciated rest area with landscaping featuring maintenance free and eatable plantings. Most of the plants are hardy and eatable, such as raspberry, lilies and serviceberry, don’t require irrigation and enable occupants as well as clients to use the outdoor areas of their environment.

The building offers a stimulating work environment. Natural lighting and outdoor views are elements that are particularly appreciated. Most areas have natural lighting due to abundant windows on the four sides of the building, situated to optimize the different lighting opportunities during the day. Five light wells add midday lighting that is both appealing and varied depending on the time of day. LED fixtures, equipped with light detectors in the two large work areas, complete the indoor lighting needs,.

Key objectives, in keeping with the premises of comfort and simplicity, were to provide fresh air and to control the immediate environment. A series of windows vents are strategically positioned around the building envelope. In addition, the mechanical systems are designed to efficiently cool and heat the different zones of the building at the same time.
