Passive House Canada Conference 2019

Moderator: Dan Gronross

Balancing Passive House with OBC in Multi-Residential Buildings
Niall Byrne and Christian Tirona, Toronto Design Studio

This presentation will provide an overview of the MEP system design for a Passive House Multi-Residential Community Housing project in Windsor, ON. Focusing on the system selection rationale and how the Passive House requirements can be integrated with OBC needs as well as the MEP strategies, this presentation will also touch on the challenging plug-load, DHW and occupancy rate considerations for community housing projects and its impact on the primary energy demand requirements of Passive House.

Lessons learned from overheating at a multi-unit Passive House residence in BC
Monte Paulsen, RDH Building Science

Passive House and other high-performance multi-unit buildings are more prone to overheating than single-family residences. This session will review lessons learned after an overheating incident at a multi-unit building in Northern BC: What design errors contributed to the incident, what operator choices contributed to the incident, what steps will be taken to avoid a repeat of the incident.

Free Cooling options for Passive House Multifamily Residential Applications
Hugh Crowther, Swegon

The outstanding thermal performance of a Passive House envelope can cause a multifamily building to require cooling at ambient temperatures as low as 0 C. Introducing mechanical cooling to resolve over heating will make it almost impossible to achieve the energy performance goals for the project when it is considered how many BIN hours there are between 0 and 25C. This program will review current methodologies being used on a range of PH multifamily projects to achieve free cooling by leveraging the ventilation system and apartment control systems. Integrating free cooling with mechanical air conditioning will also be discussed including control algorithms.
