Understanding the long term requirements of the campus facilities is a key element in developing an Integrated Sustainability and Energy Master Plan. This involved evaluating Carleton’s long-term needs and then the APPA Energy and Sustainability Assessment Tool,(ESAT) to assess our current energy infrastructure, prioritize the opportunities, and develop a comprehensive plan of upgrades for individual buildings as well as the Campus Infrastructure to: save energy and operational costs, fund renewal and indoor environment upgrades through energy savings, improve facilities for our students, faculty and staff and demonstrate environmental leadership to our key stakeholders and the community.
