Sustainable Design
.avif)



Our sustainability outlook begins with the belief that the most responsible buildings are designed to endure, adapt, and operate efficiently over time. We believe in the integration of sustainability and design, where choices are always performance-driven and research-informed.
Sustainability is not a one-size-fits-all solution. We collaborate with clients to develop unique approaches for different projects, scales, typologies, budgets, priorities, and communities. Our strategies include careful material selection, passive strategies, and systems integration.
Purposeful and responsive design
Every design feature has a function and responds to the surrounding environmental conditions.
Bespoke, human-centred solutions
Our process considers how people will use spaces while maintaining environmental and fiscal responsibility.

Zero Carbon Operations
The path to zero-carbon operations starts with a clear, integrated vision for a high-performance building. From the beginning, we consider energy performance to shape a, orientation, envelope, and systems. Our team establishes a carbon budget and sustainability strategy with purpose, carrying these high ambitions throughout the design process. By making the architecture work hard, we significantly reduce the energy required to operate the building.
Mass Timber Design
Low-carbon material choices shape both the environmental impact and the experience of occupying a building. We lower embodied carbon and define the architectural vision of our projects by using natural and renewable materials, including mass timber. To help us balance carbon data with design criteria, we employ a life cycle assessment during our iterative process.
Sustainability Frameworks
Sustainability frameworks and certifications serve as a shared language for building owners to demonstrate leadership in high-performance design. Our experience spans some of the most rigorous standards, from LEED Platinum to Zero Carbon Building Standard certifications. We also work with local and federal public policies, such as the Toronto Green Standard and the Federal Greening Government Strategy with experience in policy compliance and development.
Regenerative Site Integration
Our consideration of landscape alongside architecture is grounded by the land and what existed on site before development. MTA approaches each place as a part of a broader ecological system, creating resilient buildings that respond to and strengthen the natural conditions around them.
Retrofit and Reuse
The reuse of existing structures provides cost and carbon benefits while allowing us to preserve the cultural significance of a building. Our approach to renewal considers performance, life cycle value, and long-term stewardship. We develop retrofit strategies that elevate existing buildings to higher levels of performance while balancing the social, environmental, and civic context embodied in them.
