A step by step retrofit of an existing end terrace dwelling that will be certified to the EnerPHIT standard. The proposals involve 2 stages of retrofit that will bring the energy use of the dwelling down by over threequarters to 25KWh/m² annum, change the heat generation from gas to an electric heat pump and provide rooftop PV.
