Sustainable Design

The firm’s sustainability outlook begins with the belief that the most responsible buildings are designed to endure, adapt, and operate efficiently over time. This approach is evident in projects such as the Ontario Secondary School Teachers’ Federation Headquarters, where structural mass timber, generous daylighting, and an efficient building form are combined to reduce embodied carbon and operational energy use while supporting occupant health and long-term flexibility. Designed to target high-performance environmental standards and net-zero carbon, the project demonstrates how careful material selection, passive strategies, and systems integration can deliver environmental responsibility alongside architectural clarity and workplace well-being.

Environmental Stewardship

Sustainability at MTA is understood as a foundational lens through which design decisions are made, evaluated, and refined.

Sustainability as Collective Knowledge

MTA’s commitment to sustainability extends beyond individual projects into advocacy, research, and knowledge sharing.

Mass Timber Advancement

By sharing research, processes, and lessons related to mass timber construction, low carbon design, and adaptable building systems, the firm supports broader adoption and capacity building across the profession.

Collaborative Approach

Innovation is strengthened through collaboration, testing, and openness, pursued as a means of sustaining architectural quality over time.
