A net zero energy home generates is building with essentially no carbon footprint. They are a sub-category of high-performance homes. On average it generates as much energy as it consumes. This is achieved via a mix of energy conserving construction techniques and the use of technology to provide energy.

Installing triple glazing windows, super-insulated walls and airtight environments help minimize consumption. While these construction techniques are also used in passive house design, zero energy homes go one step further and also include installations that generate electricity: Solar PV systems installed on roofs, for instance, are designed to offset your home’s annual energy consumption and thus to achieve a net-zero energy balance.
