Our first Passive House Premium project, designed to generate more energy on site than it uses, measured over a year. This house faces due south with an asymmetric roof to maximise the solar thermal and solar PV gains. Whilst timber framed, the house has a ground floor masonry slab and stacked masonry bathrooms for thermal mass.
The 2.5 storeys will induce passive stack currents for summer purge ventilation and the souther verandah extends the PV capacity and provides summer shading to the upper and lower floors.
To top up the on-site energy generation, we plan a 250sqm ground source heat pump along with mechanical ventilation with winter heat recovery.
