Human Building Interaction Laboratory/Delta Controls Laboratory

The Delta Controls Lab provides a portal to the wealth of information carried by the Canal Building’s building automation system (BAS), including energy use, thermal comfort, lighting/daylighting, indoor air quality, heating, cooling ventilation, and green roof performance.

Green Roof Teaching and Learning Centre

The overall objective of this project is to establish a green roof teaching and learning centre at Carleton University, and use the data collected from the green and conventional roofs to compare their water budget.

Graduate Student Openings

Graduate students (MASc or PhD) with a background in heat transfer, thermodynamics, programming, energy systems, and/or building science/physics are needed to pursue research in the following topics. Please contact Prof. O’Brien if you have the above background and are interested in researching these topics. Co-supervision by another professor in CEE or another department (e.g., Mechanical and Aerospace Engineering) is also a possibility. The right candidates will be given the opportunity to work on important problems with significant impact on industry, the opportunity to work with industry partners, and competitive compensation.
