This monitoring study aims to generate field performance data from a highly energy efficient building in the west coast climate as part of FPInnovations’ efforts to assist the building sector in developing durable and energy efficient wood-based buildings. A six-storey mixed-use building, with five storeys of wood-frame residential construction on top of concrete commercial space was completed in early 2018 in the City of Vancouver. It was designed to meet the Passive House standard. The instrumentation aimed to gather field data related to the indoor environment, building envelope moisture performance, and vertical movement to address the most critical concerns among practitioners for such buildings.
The research conducted will provide new climatic data which takes into account certain extreme weather events being attributed to climate change to minimize and/or prevent the risk of failure of tall wood buildings and mass timber structures. The project will offer guidance on the design for durability of tall wood building enclosures and fill existing gaps in knowledge about the extent of the effects of the future climate conditions and extreme weather events (e.g. heat waves, rainfalls, wind storms, etc.) on the resistances to deterioration of building materials, air leakage, vapour diffusion, and water ingress.
