A Net Zero Energy (NZE) home is one that is designed, modelled and constructed to produce as much energy as it consumes on an annual basis.
- NOT NZE “as operated” – but uses assumptions for occupant consumption (Plug/occupant loads in NZE homes are between ½ to ⅔ of total energy use)
- The energy produced is a) generated on-site and b) renewable.
- NZE can be achieved via net-metering AND/OR on-site generation and storage.
- It includes all forms of energy (ie passive and thermal) including acknowledgment of gas and electrical base loads.
A NZE Ready (NZEr) home is a NZE home that has not yet installed the renewables.
