(BAS) Conservation & Sustainability

The Bachelor of Architectural Studies (Conservation & Sustainability) program offers a specialization unique among all undergraduate architecture programs in Canada. Since 2009, this stream has focused on the conservation of historic architecture, paired with a study in the principles of sustainable design.

A growing proportion of architectural work – particularly in sustainable design – involves renovations with sustainability upgrades, or the adaptive reuse of existing buildings. Following the Understanding, Planning, and Intervening method set out in the Guidelines for the Conservation of Historic Places, students in this program learn to study and assess existing architecture so that they can formulate creative and compatible design solutions for historic built fabrics. Conservation studio projects are founded on strong historical and social understanding, along with deep knowledge of conservation theories.

Benefiting from collaborative course delivery between the School of Architecture and the Department of Civil and Environmental Engineering, students in the BAS Conservation and Sustainability program receive in-depth technical education on integrated building systems, architectural materials and assemblies, green building techniques, and hands-on practice with heritage documentation. Through the study of conservation theory, ethics, and best practices, students also learn to research and analyze existing architecture.

Notes About Workshops

Workshops are hands on, specialty courses that students may apply to take as “free electives.”  To apply to participate in a workshop, please do the following:


Step One: Review the workshop offerings and ensure you meet the prerequisites.

Step Two: Submit the required application via email to the instructor by the application deadline. 

Step Three: Await a decision, which you will receive via your Carleton email within three weeks of the application deadline. 

Step Four: If you are approved to take the requested workshop, please forward the message you received from then instructor to the Undergraduate Administrator.  You will also need to complete and submit an override request form on Carleton Central to secure a place in the course.


Please note: Application to a workshop does not guarantee course access. All applications are reviewed by the instructor after the submission deadline. Students are encouraged to register in an alternate course in the event they are not accepted into a workshop.
