Carleton and Queen’s University (with Algonquin College) competed in
the US DOE Solar Decathlon 2013 Completion as Team Ontario.
Faculty Advisors at Queen’s (SH) and Carleton (CC) are researchers
within SNEBRN and many of the goals of the Decathlon competition
were consistent with the research goals of the SNEBRN.
The project has provided many opportunities for collaboration with
industry and the interaction with many undergraduate and graduate
students across the three institutions.
The project also provided a high visibility venue that promotes the goals
of the SNEBRN and provides many opportunities for the development
of HQP.

4TRNSYS Simulation
The system was designed and modelled using TRNSYS
Sensitivity studies were conducted to investigate the effects of
certain parameters on the performance of the system

Students from Queen’s University and Carleton
University built, instrumented, and tested the
core of the IES in the Queen’s University Solar
Calorimetry Lab.
6Simulation and Experimental Findings
Results were compiled in the M.A.Sc Thesis and two
journal papers were accepted for publication
After refining the TRNSYS model with experimental data,
simulations suggest that the IES may achieve an annual
free energy fraction of 0.506 for DHW, space-heating,
cooling, and dehumidification
From the simulation sensitivity studies it was found that
Glazed flat plate collectors outperform evacuated tube collectors
Heat pump characteristics and control had the largest impact
Thermal stratification is also an important factor in the design
The experimental analysis indicated the higher heat pump
load side flow rates improves the COP of the heat pump
but destroys stratification in the hot tank which reduces
the overall performance of the system
7Air Handling Unit (linked to 1.3)
A heating/cooling and
dehumidification Air
Handling Unit (AHU) was
also designed and built with
the assistance of CANCOIL
