When the outdoor airprocess and close collaboration withAqua Coast Engineeringtemperature is below 13 C to 12 Cthe supply air setpoint is 22 C. When the outdoor air temperature is above25 C, the ERV and heat pump will run in cooling mode to maintain air temper-ature in the suites at 13 C. Each suite has an electric baseboard controlled via a local thermostat to provide supple-mentary heating to meet the demands of the peak heating loads.RISING TO THE CHALLENGEAchieving Passive House design required innovative thinking from all parties, especially when building an energy-smart building in Whistler's alpine climate. For example, we used prefabricated wall panels from a controlled manufacturing plant that not only shortened the time needed to fully enclose the building, which reduced the building's exposure to the elements during construction, but also provided the desired level of airtightness,says Wai.Additionally, when it was determined that vinyl windows were inappropriate for the cold climate, the project team opted for Passive House-certified, drained aluminum-clad wood-framed windows. Doing so was effective in enhancing the buildings heating FALL/WINTER 2023 13"
