This system is assessed and optimized using TRNSYS simulations. Results indicate that it is possible to obtain a renewable fraction (similar to the well-known solar fraction) greater than unity. This is achieved by using 10m2 of evacuated tube solar collectors, two 600 liters storage tanks (including one for selling excess solar to adjacent buildings), a grey water heat recovery unit, and desuperheaters from ground-source heat pumps.

The new Concordia Sciences Building (CSB), located in Montreal, has a total floor area of 32,000 m 2 . The size and the complexity of the heating, ventilation and air conditioning (HVAC) and heat recovery systems make the modeling process a challenge and an excellent opportunity to evaluate the capabilities and features of EnergyPlus in this particular context.
