As part of our Sustainability Strategy Carleton University has partnered with Honeywell to work on a long term program to identify opportunities and implement initiatives designed to conserve energy and create sustainable solutions for our campus.

This comprehensive approach to facility upgrades and enhancements will improve the indoor environment, providing consistent lighting levels, better temperature control and reduced drafts. It is also expected to provide significant savings in utility costs through higher efficiency and reduce carbon emissions.

Wider to individual building renewal is Carleton’s Energy Master Plan. The plan outlines our goals and objectives for managing, conserving and reducing energy consumption, alongside costs and estimated savings for proposed measures, as applicable to the whole campus.

Current Program:
