One of Canada’s first Net-Zero Communities

In Westport Ontario, is Canada’s first net-zero community being built by Land Ark Homes. Homesol is Land Ark’s net-zero energy advisor. We’ve been helping Landark since the inception of this community. We’ve been consulting with them on the performance aspects and the building science aspects of designing the house from insulation levels to airtightness details to mechanical specs.

Below are the specs for the model above that is completely net-zero thanks to solar panels installed on the roof. But each homes’ numbers rate very similarly as they are designed with net-zero energy loss in mind. Every home in the community will be built to be solar-ready so once sold the homeowner’s have the ability to easily add a solar panel system on the roof to live in a complete net-zero home.
