这是由STGM Architectes设计的STGM总部办公楼。该项目位于魁北克市博波尔区，毗邻Estimauville生态居住区。该项目建筑面积达1000平方米，两层高，设计重点在于生态友好、建筑创新。该建筑通过纵向形式一体化、面向太阳、轻型木制结构、精心的材料搭配、高效的系统以及提供低生态足迹的设计手法，成功地为用户提供了特别的舒适体验。

高性能混凝土板结合了铅笔柏，创建了一个兼具简介与动态的令人印象深刻的形象，让人关注虚与实之间的关系，赋予建筑一种与时间、时尚不符的优雅。从初次草图设计开始，建筑师就试图以高水平的可持续为该项目的核心设计原则，运用了各种必要策略以达到LEED-NC铂金标准。以此为目标，从舒适性、简洁性和连贯性都被列入基本原则。

在初次方案中，场地自身的特性决定了该建筑应以极简设计为理念。有限的地面承重力限定了最小建筑重量，因此使用了轻型的韧性木框架结构以及低生态足迹，最终被证明是最佳的解决方式。该结构使用了一小部分实木和大部分锯制板（lumber），组成了小型预制桁架和托梁，从而达到轻型结构和大跨度（14米）的效果，有助创建一个开放的工作区域。木质屋顶桁架被整合为一种设计元素，暴露在外，赋予了建筑独特的外观。

From the architect. 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.

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.

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.

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.
