Sustainability Report

Retaining the existing cottage, including most of its components, was approached as a strategy of material reuse and reduced carbon impact. The clients initially intended to demolish the building and rebuild it from scratch. Following further assessment, the decision was made to preserve the structure, largely due to its location and its specific character as a seasonal dwelling. This approach also reduced the volume of construction waste and limited the fuel consumption associated with transporting debris off-site.

Operational emissions strategies 

• During the design phase, primary reference was given to compliance with the NovoClimat 2.0 standard, a provincial government programme that brings together construction requirements aimed at achieving energy-efficiency objectives. The standard addresses energy performance, comfort, indoor air quality, and construction quality in residential buildings. As with Bourgeois / Lechasseur architects’ residential projects more broadly, the design was developed to meet and exceed these requirements, which are widely recognised in Quebec. Particular attention was required to ensure compliance in the context of rehabilitating the existing cottage. Floor assemblies, walls, windows, and the roof were upgraded to achieve the required levels of energy performance.
• The doors and windows were manufactured by Shalwin, a local company that uses North American–sourced aluminium. These components were selected for their durability and energy performance. 
• The residence is equipped with a geothermal system for heating and ventilation, using ground temperature to reduce energy demand. 
• A home automation system allows for precise control of heating and lighting throughout the day.

All materials were selected for durability and low maintenance requirements. Eastern white cedar was used as the exterior cladding. This locally sourced wood, originating from eastern Quebec, offers resistance to weathering and decay and was produced by Debois Blouin.
