Designing a Net Zero Ready building

Designing a Net Zero Ready building takes careful consideration and planning, starting with the building envelope — the physical barrier that separates indoors from outdoors.

Increasing insulation keeps the temperature inside the home comfortable, and prevents heat loss.

One place heat can slip out is at studs, which is why we use a staggered stud configuration.

Windows can cause both heat loss in the winter and solar heat gain in the summer. We use high-efficiency windows and consider the location to reduce sun exposure.

We also use a high-efficiency furnace and water heater with air-source heat pumps — which uses the outdoor air as the heat source in winter and as a heat sink in summer — that are up to three times more efficient than traditional systems.

Plus, a drain water heat recovery system pre-heats incoming cold water to reduce the amount of energy needed to heat it.

These design considerations result in a home that’s built to Net Zero and Net Zero Ready standards — some of the highest building standards in Canada.

Old-school ways of building are broken
Traditional construction methods are resource-heavy and inefficient, so we decided to change that.
