Sustainability has become a key consideration in both society and engineering. There is a growing need for engineers with expertise in the closely related areas of heritage conservation and sustainable building design. Carleton’s program in Architectural Conservation and Sustainability Engineering teaches students a modern approach for the design and retrofit of buildings that holds sustainability as the guiding objective while respecting architectural history and significance. Students learn to consider the life cycle costs and environmental impacts of building materials, energy demand, and the effective reuse and conservation of existing structures. Students in the program work closely with Carleton’s architecture students and have the option between following a Structural stream or an Environmental stream after their second year.
