What Is Net Zero?

And how can you renovate your home to Net Zero Standards?


What Does Net Zero Mean?

A Net Zero Energy (NZE) house is designed and built to reduce household energy needs to a minimum and includes on-site renewable energy systems, so that the house may produce as much energy as it consumes on a yearly basis. An NZE home is not necessarily an “energy autonomous” house or “off-grid” house, as it can be connected to the electricity grid, so that it can supply electricity to the grid when it is producing more than it needs and draw from the grid when household demands exceed the amount of electricity produced on site. Taken over the year, the energy supplied to the grid balances the energy drawn from the grid, thus achieving net- zero annual energy consumption.
