Energy Efficiency

Wunderhaus is arguably the best-performing domestic building on the market; it easily meets the Government’s legislative 80% carbon reduction target for the building industry, while its Passivhaus standard ensures peerless thermal performance, so efficient that it feeds energy back to the grid.

Wunderhaus is a zero energy house, with an MVHR system providing continuous fresh filtered air, recovering 93% of the heat provided by a 5kW air source heat pump for underfloor heating and hot water.

Features

A virtually invisible, revolutionary photovoltaic energy system provides 11.5 KW of electricity.

Energy is stored with 13.5kWh battery, which can also provide power in case of a power cut.

A dedicated electric vehicle charging point is provided.
