Summary

This paper presents an analysis of five energy efficient heating and cooling systems for a high performance mid-rise apartment in two Canadian regions: Calgary and Montreal. The analysis was performed using the TRNSYS simulation tool comparing the annual primary and secondary energy consumption, utility costs and greenhouse gas emissions of proposed technologies as well as the 20 year life cycle cost. The five systems selected for comparison include (1) a conventional mid-rise apartment heating and cooling system, (2) boiler/cooling tower water source heat pumps, (3) ground source heat pumps, (4) a cogeneration unit sized to meet the heating load of the building and (5) a cogeneration plus electric driven heat pump system. In Calgary, the cogeneration only system demonstrated the greatest primary energy savings, utility cost savings and greenhouse gas emission reductions of all systems evaluated primarily because of the utility rate structure and electricity generation in the region. The ground source heat pump system demonstrated the greatest secondary energy savings. In Montreal, the ground source heat pump system was predicted to have the greatest savings in all four categories. Evaluating the 20 year life cycle cost of the systems, the base case proved to be the most economical, demonstrating the challenges of implementing energy efficient systems in Canada due to low utility rates.
