The buried pipes that will help U of T turn carbon positive
April 19, 2022 – National Observer – Morgan Sharp
The usually bustling downtown campus of the University of Toronto lay empty of students and faculty during long pandemic-enforced absences, and the construction crews working on a major environmental project took advantage.
Initially envisioned as an effort to remove cars from King’s College Circle, the landscaping project morphed into something more ambitious — a geothermal exchange system that in conjunction with major building retrofits and other measures will help the St. George campus become carbon positive by 2050, meaning it will collect more carbon than it emits.
… More than 300 geoexchange wells have been drilled under the expansive green space at the front of the campus, each over 250 metres deep. These will allow heat produced in the summer to be stored underground and drawn on in the winter, with the process reversed to use winter’s chill to cool summer days.

How To Heat Your Home Without Heating The Planet
Brett Tryon – Updated November 2, 2021 – Chatelaine
You don’t need to burn fossil fuels to heat your home.
Heating your home with fossil fuels doesn’t just keep you warm—it creates emissions that warm the planet. Home heating is Canada’s largest source of residential greenhouse gas emissions. The good news: there’s a more environmentally conscious option that can help you save energy, shrink your carbon footprint, and build Canada’s resilience to a changing climate and fluctuating fuel prices. Here’s what you need to know about switching from a gas furnace to a heat pump—and why you should consider it.
Architects Climate Action Network Calls for Regulation of Embodied Carbon
The majority of a building’s carbon emissions happen before it’s even opened.

The clever frontispiece (shown to the left) of the report “The Climate Footprint of Construction” says it all: above the line is the finished building, while below the line are the power plants, freighters, transport trucks, cranes, factories, and mines that make all the stuff that goes into a building. All of those industries and processes emit carbon dioxide and equivalent gases, and added together are known as embodied carbon. It’s unseen and has been mostly ignored, but according to the report’s authors, the Architects Climate Action Network (ACAN), can total more than 75% of a building’s lifetime carbon emissions.

Designing to the Passive House standard of energy efficiency and airtightness is hard. Designing social housing on a tight budget to the Passive House standard is incredibly hard. That’s why the work of Emma Cubitt and Invizij Architects is so interesting and important.
The 10 design commandments for cutting your building’s embodied carbon
“When I first came here, this was all swamp. Everyone said I was daft to build a castle on a swamp, but I built it all the same, just to show them. It sank into the swamp. So, I built a second one. And that one sank into the swamp. So, I built a third. That burned down, fell over, and then sank into the swamp. But the fourth one stayed up. And that’s what you’re going to get, son, the strongest castle in all of England.”
King of Swamp Castle, Monthy Python’s Holy Grail
This guide will show architects and other building designers how to effectively reduce the embodied carbon of a construction project. Avoid building castles on a swamp and follow these design commandments to achieve substantial and cost-effective emissions reductions, and learn how to achieve low carbon design in your projects.

British Architects Declare Climate and Biodiversity Emergency
For everyone working in the construction industry, meeting the needs of our society without breaching the earth’s ecological boundaries will demand a paradigm shift in our behaviour. Together with our clients, we will need to commission and design buildings, cities and infrastructures as indivisible components of a larger, constantly regenerating and self-sustaining system.
