Path to Zero: this is a Decarbonization Project!

June 16, 2021 | Amy Henderson

Given our focus as a firm, and how many deep energy retrofit projects we’re doing, we thought it would make sense to give a little explanation, to let people know what’s going on in our heads and in these buildings.

What’s it all about? These buildings have a plan to stop using fossil fuels—to get to zero carbon. Since we’re in a cold climate, it begins with simple but thorough conservation through insulation and air sealing. Decarbonization continues by using electricity to efficiently power the entire house, using heat pumps for HVAC, water heating and the dryer, and induction for cooking. Can’t decarb if you’re using fossil fuels, so the gas line comes out! Solar PV on the roof then allows us to offset most or all of the annual site energy use. As the electrical grid is increasingly fed by wind and solar, coal and gas generation can be retired, but only if buildings are very energy efficient!

A great benefit of this process is that the home is made more comfortable and durable, with greater indoor air quality for a healthier environment. It’s not cheap or simple, but much of it can be planned to occur with the end of service life of various components such as exterior finish, windows, and mechanical equipment.

The following blog posts will explore a decision flow chart for the decarbonization process. Stay tuned!
