Research interests and activities
Research activities are focused on development and integration of solar energy systems into buildings to generate electricity, useful heat and for daylighting. My long term vision is the realization of solar buildings operating in Canada as integrated advanced technological systems that generate in an average year as much energy as they consume.
A key element of our approach is that solar technologies are integrated in an optimal manner with energy efficiency measures, with the building envelope and with HVAC systems, so the potential energy savings are even higher than separately applying the two approaches and reductions in total cost may be realized.
I am looking for new graduate students and postdoctoral fellows with strong backgrounds in building engineering or civil/mechanical engineering and related fields (applied physics, architectural engineering etc) to work in exciting projects using a new state-of-the-art solar simulator and environmental chamber – an internationally unique laboratory.

Funded by NSERC, NRCan, CMHC, Hydro Quebec and other industries in the SNEBRN Network:
- Development of innovative photovoltaic-thermal systems and their integration into the building envelope and with HVAC systems;
- Solar design, modeling and daylight control of perimeter zones in office buildings;
- Integrated modelling, design and control of direct gain systems with floor heating;
- Load and demand management in solar-optimized buildings;
- Modelling and design of net-zero energy solar buildings;
- Test of novel concepts in a large scale solar simulator – environmental chamber laboratory; this unique laboratory enables testing of solar systems and advanced building envelope components under simulated sunlight and exterior temperatures in the range -40 C to 60 C. This internationally unique lab includes a large scale solar simulator.
Major research facilities of my team are the Solar-Daylighting lab on the 16th floor of the EV building and the newly built Solar simulator – Environmental Chamber Laboratory. The Solar-Daylighting lab and its adjacent atrium as well as the roof of EV and BE will be used for many unique projects of the Network. A variety of equipment has been acquired, including solar instruments, infrared camera, particle image velocimetry system and heat flow meters. Our lab also includes an artificial sky (3 x 3 x 3 m) facility.
The large scale solar simulator shown in the figure below (left) integrated with a two-storey high environmental chamber (right) is a unique facility that will allow the testing and development of building-integrated solar systems and advanced envelope assemblies under a broad range of simulated outdoor temperatures and solar radiation levels.
Dr. Athienitis and his students played a key role in the design of the EcoTerra - an innovative solar house built under the EQuilibrium housing demonstration program conducted by CMHC. The house includes roof building-integrated photovoltaic/thermal (BIPV/T) systems designed by Athienitis and his students. Simulation models for research, design and control, as well as innovative whole-house energy systems aimed at achieving net-zero annual energy consumption have been developed. These systems integrate our BIPV/T designs with existing technologies such as passive solar and ground source heat pumps. A BIPV/T roof based on concepts and designs developed by our group was built as a complete prefabricated module in the factory of our partner Alouette Homes, who received the "Reconnaissance - Recherche et développement en habitation" award of the Quebec Construction Association in 2008 with special mention of our team’s role in the research. This is the first time that a complete roof section is built as a hybrid solar-thermal and electricity generating system (BIPV/T roof), complete with wiring, ducting and ready for assembly with other building modules.
The most recent demonstration project involving a full scale facade-integrated BIPV/T system at the JMSB building of Concordia University received much international attention, including a special program on Discovery Channel. It is the world’s first fully functional architecturally integrated BIPV/T façade to use high efficiency distributed air inlet technology.
