Legacy Passive House, Whistler, Canada
1020 Legacy Way – Whistler, BC is a low-rise apartment building project built and certified to Passive House standards. The development consists of 24 rental apartment units to be operated by the Whistler Housing Authority.
Challenge
Meet and exceed Passive House standards and sustainability requirements as per Whistler's resort municipality's guidelines
Solution:
In collaboration with HVAC Sytems, a key part of this design included a centralized ventilation solution, including a highperformance ERV, integrated VRF post-heating and post-cooling, and control dampers. SWEGON GOLD SERIES Passive House Certified ERV with a heat recovery ratio of +85% and VRF heat pump system with COP of 4.4 meet the building’s challenging air filtration and energy targets. SWEGON REACT DAMPERS are integrated into the system design to provide individual suite control, cooling and heating to each suite, and a free cooling option.
Result
HVAC SYSTEM’S centralized ERV, VRF heat pump and REACT damper solution for Whistler Housing Authority saved 30% on the equipment capital cost compared to a decentralized ventilation solution. The VAV solution in conjunction with the centralized system has the potential to present large
savings on operating cost, avoid over/under ventilation and provide cooling in each suite. Providing mechanical equipment with builtin control smooth the commissioning and balancing process for this project.
