Passive House Canada Conference 2018

The Opportunities and Challenges of Building to Passive House Standards in a Remote Community: Lessons Learned from a Post Occupancy Evaluation Study
Alex Hutton, Fraser Health Authority, & Ghazal Ebrahimi, Fraser Health Authority
Vancouver Coastal Health (VCH) Authority rebuilt a staff-housing complex, which was damaged by fire to Passive House standards to reduce GHG emissions and energy costs. Combining modular construction techniques with Passive House standards helped achieving a time-sensitive, sustainable, and cost-effective solution to housing demand in a remote community in Northern BC. The results of the post-occupancy evaluation of this facility and the co-benefits of moving towards zero-carbon design will be discussed. The presenters explain how the organization's strategic framework and commitment to innovation and sustainability resulted in overcoming the challenges and realizing a high quality, energy efficient building in a remote community.

High Performance Measured: Modelled Versus Measured Energy Use
Brittany Coughlin, RDH Building Science Inc., & Eric Catania, RDH Building Science Inc.
Passive House has become known as a standard that delivers measured performance. Post-occupancy evaluations are demonstrating heating energy demand in line with modelled results for numerous Passive House buildings that have been in operation for several years. This presentation will provide a summary of measured energy use for a variety of Passive House buildings. Measured energy use will be compared to modelled use for building types including single family, multifamily, and commercial buildings. The presentation will summarize lessons learned to inform future PHPP models and Passive House building designs.
