The house has been designed to meet the RIBA 2030 Climate Challenge standards for operational energy use and embodied carbon. It is designed to be whole life net zero carbon. The standard includes a maximum annual energy consumption of 35 kWh/m2/yr which is supplied by an 7.2kWp output roof mounted photovoltaic cells. The house is heated via a ground source heat pump and passive solar gain collected in a South facing sunroom. There is a wood burning stove in the sitting room and the flue is routed through the centre of the house to ensure maximum heat is retained in the building. The design has been assessed through an embodied carbon calculator.
