Passive House principles offer the best path to Net-Zero by minimizing the load that renewables are required to provide.
Net-zero homes make as much energy as they use. They are connected into the grid like other homes, but they supply power as well as consuming it. This allows them to use the grid as a 100% efficient battery, while also helping to get more renewable solar power available for the entire grid to use.
The Canadian government has identified Net-Zero ready buildings as a key part of the Action Plan for a Low Carbon Economy.
It is much cheaper to save energy through design, details and efficient mechanicals than it is to buy more solar panels.
Often, the key limitation to achieving Net-Zero is having sufficient roof area on your house to accommodate the solar panels. With Passive House we reduce the energy use by 60% making it possible to fit the needed panels on the roof. Most homes built to code require far more panels than the roof can handle. Standard built homes use much more power than they can reasonably generate.
Passive House, with a focus on energy conservation and high-performance building envelopes, is the path to Net-Zero housing.
For homes far from connections to the power grid, achieving Passive House is only the first step.
Unlike Net-Zero homes, Off-Grid homes need the capacity to store large amounts of energy and often require a variety of energy generators. When we design an off-grid home, we start with the Passive House approach to first minimize energy use, we then further evaluate the energy needs of your house based on your specific design and lifestyle to optimize the size of your solar array.
Using a variety of energy modeling tools and worksheets, we can determine sizing requirements and provide realistic system integration advice and coordination so you can move towards a more energy-independent lifestyle.
