6 Key Green Building Trends in Quebec for 2025
Building a Greener Future Rooted in Quebec
In 2025, green construction in Quebec is no longer a niche choice—it’s a necessary path shaped by climate, economic, and social realities. The building sector—historically energy-intensive—is undergoing a major transformation. Driven by new regulations, growing environmental concerns, and a collective will to build differently, the industry is evolving quickly, yet with respect for tradition and local heritage.
Builders, architects, developers, and homeowners are adapting to a changing landscape: climate urgency, rising costs, material shortages, and a desire for healthier, more sustainable, and locally rooted living. The year 2025 marks a turning point where innovation blends with simplicity, respect for the land, and efficiency.
Here are six major trends defining Quebec’s green construction sector in 2025: stronger regulations, the rise of bio-based materials, modular prefabrication, smart eco-design, circular economy practices on job sites, and a return to traditional techniques adapted to our northern climate.
- Strong Regulatory Framework Driving Green Building
Since the launch of the Plan for a Green Economy 2030, Quebec has been strengthening its legislative tools to meet climate targets. In 2025, this plan allocates over $10 billion to the energy transition, including building sector initiatives. Federal energy efficiency standards also set high-performance requirements for new builds and major renovations.
This framework encourages greener practices and fosters a climate for responsible investment. Contractors are now incentivised—and often required—to use low-carbon materials, maximise thermal efficiency, and document environmental impact. As a result, sustainable construction is no longer a niche market—it’s the new norm.
- Rise of Bio-Based and Eco-Materials
Demand for bio-based materials is booming in Quebec in 2025. Sourced from plant or animal biomass, options such as hemp, straw, wood fibre, and cellulose insulation stand out for their thermal performance, low carbon footprint, and circularity.
Locally produced, these materials reduce transport costs and boost the regional economy. They also promote healthier indoor air quality, free of toxins and VOCs. Perfectly suited to Quebec’s climate, they offer excellent humidity regulation and long-term durability despite extreme seasonal variations.
- Modular Prefabrication as an Eco-Friendly Alternative
Modular construction is gaining traction among municipalities and developers. Manufactured in controlled factory environments, modules can reduce waste by 50% to 90% compared to traditional job sites. This approach shortens delivery times, minimises human error, and reduces budget overruns.
Mass timber is often used in prefabrication, adding a bio-based dimension. Lightweight yet strong, it stores carbon for decades. Combining efficiency, durability, and environmental responsibility, modular building also showcases Quebec’s carpentry expertise.
- Integrated Eco-Energy and Smart Design
Energy intelligence is central to 2025’s sustainable building projects. Green buildings integrate advanced technologies: smart thermostats, humidity sensors, automated lighting, heat recovery ventilation (HRV) systems, and hybrid solar panels.
Bioclimatic architecture is also making a comeback, with optimised window placement, natural heat and light management, and careful material selection for thermal mass. This blend of traditional design principles and modern tech ensures optimal comfort while reducing energy bills.
- Collaboration, Waste Management, and Circular Economy on Site
Circular economy principles are becoming standard practice on Quebec construction sites. Through collaboration between contractors, suppliers, engineers, and architects, projects are designed to prioritise reuse, recycling, modularity, and waste reduction from the planning stage.
Material management platforms and environmental training sessions are now common. The Quebec Construction Association (ACQ) actively promotes these sustainable practices, creating a culture of shared responsibility across the entire value chain.
- Back to Basics: Reviving Traditional Building Techniques
In a fast-paced world, more Quebecers are returning to the essentials. Traditional methods—like cob walls, raw wool insulation, and solid timber frames—are regaining popularity. Proven effective in our northern climate, they also promote local self-reliance, resilience, and simpler living.
This isn’t about rejecting technology, but about combining it with ancestral know-how. In 2025, it’s not unusual to see an eco-home featuring straw bale insulation alongside advanced smart-home systems—a perfect example of Quebec’s heritage adapted for the future.
