Join our free, Building Conversations webinars series hosted weekly by our CEO, Chris Ballard. Each week, Chris will interview experts from the Passive House community as they share their stories of what they have learned from their experiences. We will then open the discussion for you to ask Chris and his guest any questions related to the topic.
In case you were unable to attend the live event or would like to re-watch the webinar at your leisure, the recording can be viewed by visiting our YouTube Channel. Subscribe to get notified of new uploads!
The Importance of Carbon Storage in Building Materials with Chris Magwood (Executive Director, The Endeavour Centre)
Chris Magwood is obsessed with helping reverse climate change by making carbon-storing buildings that are also healthy, beautiful, efficient and inspiring. Chris is currently the executive director of The Endeavour Centre, a not-for-profit sustainable building school in Peterborough, ON and has helped to establish Builders for Climate Action, which will be rolling out a set of tools and policy options to help governments, designers and builders reverse climate change with their buildings. Chris has completed an MA at Trent University and his thesis, Opportunities for Carbon Removal and Storage in Building Materials was published in the fall of 2019.
In our conversation with Chris, we will discuss how carbon storage in building materials works and what it means. For the Passive House community it will be important to consider BOTH energy efficiency and material emissions. As Chris will explain, in his recent study he examined a single family home and a small MURB. The study showed how wide a spectrum the material emissions could represent depending on material choices. The same building with the same level of performance can range from having up to 400 kg of GHG emissions per square meter of floor area to providing net storage of 150 kg. Could a highly efficient home made from high emissions materials actually be worse for the climate? The study also makes it clear that we need both energy efficiency and material emissions to be considered and that when we combine good material decisions with PH levels of efficiency we can actually make buildings that help reverse climate change.
