The Dufferin Residence will be a Certified Passive House addition and EnerPHit retrofit to a heritage listed building, compounding the challenges for this project. Keeping with the look of the neighbourhood, approval from the city finally allowed the project to break ground at the end of 2014. Pushing the envelope further, 21” R-67 ICF walls were chosen, with the hope of comparing construction costs of similar R-value wood construction walls. The “penthouse”/rooftop access will be composed of prefabricated, pre-insulated panels.
