How Long Can Passive House Buildings Stand Thermally Resilient During a Power Outage?
Presented by: Aylin Ozkan - RWDI, Joel Good - RWDI
The frequency and severity of climate disasters are escalating. Often these weather events occur during periods of extreme heat and cold and can knock out power for extended periods of times. As a result, most buildings quickly get too cold or too hot, unable to deliver occupant shelter needs under these conditions. To increase our preparedness for climate disasters widely, it is advised that multi-unit residential and larger scale community buildings should be a focus of thermally resilient design in order to provide safe, comfortable gathering spaces for people in need during a prolonged power outage. The goal of this presentation is to exemplify the performance of Passive House buildings (MURBs and community hubs) during a prolonged power outage. We will also discuss their annual performance with/out the active systems (HVAC, lighting and equipment), input and emphasize the design measures to improve the performance.
1. What is thermal resilience? Why it is important?
2. How we evaluate the performance during a power outage?
3. What are the design measures to improve the building performance during extreme weather events?
4. Are Passive House buildings thermally resilient? How do they achieve it?

2) Economics: Energy Savings based on payback
3) Collaboration between an energy modeler, designer & equipment manufacturer with example projects
Presented by: Cillian Collins - Perkins&Will, Manuela Londono - Perkins&Will
We view carbon holistically on projects, through a whole life cycle carbon analysis which evaluates both operational carbon and embodied carbon. As buildings are transitioning towards net zero operational carbon, embodied carbon remains as part of a project's negative environmental impact and requires critical analysis. We have established a stepped process through each phase of design which builds on our holistic carbon thinking and maximizes the embodied carbon reduction potential. As we design and select materials, we analyze materials, such as envelope enhancements, against both long term operational carbon as well as immediate embodied carbon reductions associated with their manufacturing.
With a multi-year stepped embodied carbon reduction target which is currently a minimum 20% on all architectural and interiors projects, approach to material selection is an integral part of the design process that design teams must embrace.
1) Approach to holistic carbon thinking
2) Evaluating embodied carbon together with operational carbon savings
3) Where to start, and stepped approach to reducing embodied carbon on projects

Blind Spots within Blind Spots – How Passive House Helps Mitigate embodied Carbon within Refrigerants and Mechanical, Electrical, and Plumbing Systems
Presented by: Jeremy Field - Integral Group
Embodied Carbon has been recognized as a blind spot of the building industry, and effort has gone into mitigating the carbon emissions tied to steel, concrete, wood and other structural and enclosure materials.
However, other major systems hiding within the walls of our buildings are not generally considered, but are made of some of the most carbon-intensive (per kg) materials - the systems that keep our buildings ventilated, sanitary, and powered.
As Canada works towards a zero carbon building sector, Passive House buildings are uniquely situated to support achieving some of the most drastic reductions in these blind spots within a blind spot.
1) What typical embodied carbon models do and do not address
2) How embodied MEP + Refrigerant emissions stack up against embodied
