Part of a unique project that integrates a solar energy system at a neighborhood scale, the Lac-Mégantic microgrid pavilion is a multifunctional shelter covered with 72 solar panels that produces, stores, manages and distributes energy. A true living laboratory, the pavilion serves as a technological showcase for Hydro-Québec and as a year-round gathering place for the citizens of Lac-Mégantic.
Since the Pavilion is a practical and tangible application of solar energy technology, it had to be designed for optimal performance of the solar panels, particularly in terms of surface area, tilt and orientation of the roof. However, the design team also wanted to demonstrate that such a structure could contribute to the community’s well-being and be attractively integrated into an urban environment without dominating the landscape.
The structure, volumes and materials of the pavilion were chosen to blend into the landscape and to allow a good visual clearance for the nearby train station. Creating a sense of lightness, the dark color and simplicity of the steel columns diminish the visual impact of the structure, accentuating the impression that the roof is floating. Contributing to the warm and inviting atmosphere, le lighting concept under the roof was also carefully chosen to protect the regional dark sky reserve of Mont-Mégantic.
Inspired by the region’s archaeological heritage, the architectural concept for the pavilion pays tribute to the first occupants of the Lac-Mégantic territory during the Paleoindian era and their sustainable way of life. Reminiscent of the spearheads they used that were discovered at the Cliche-Rancourt archaeological site, the triangular « V » shape is found in the wood structure of the pavilion’s roof, in the angle formed by the steel columns « spiking » the ground, and even in the paving. The use of wood and stone is also a nod to the materials that made up the lances. The structure thus links this 12,000-year-old ancestral technology with the eco-responsible technologies of the microgrid, both ingrained in a way of life that is environmentally friendly.
In keeping with the project’s ecological values, the design team favored sustainable materials with a small ecological footprint, such as granite and wood. The inclusion of these materials seemed particularly relevant, as they have long been the main driver of the local economy. The use of wood particularly makes the space more inviting, especially when paired with granite and steel. They create an interesting contrast: the color, lightness and natural fiber of wood stand out against the heavier, colder-looking mineral and metal materials. In particular, the addition of wood under the roof creates a brighter and warmer space during the evening: the golden light is reflected by the warm wood, which further defines the area and establishes a cozy ambiance. Finally, although glued laminated wood was chosen for its resistance to swelling, the roof was designed to ensure that it is not exposed to the elements and can remain beautiful and functional for years to come.
By promoting more sustainable ways of producing and managing energy, the microgrid pavilion contributes to the research in this field and raises awareness for renewable energy. In addition to the environmental benefits, this project encourages citizens to get involved in sustainable choices and contributes to the quality of life of the community.
