This case study looks at the impact on heating and cooling energy demand in retrofitting of my own home in Canberra with the goals of comfort and health. It is a 1960’s 4-bedroom brick veneer with a timber floor and single glazed steel framed windows.
This would be a very cold house to live in in the Canberra climate and essentially impossible to meaningfully heat in its existing state. However, if the building envelope is fully insulated, air leakiness is minimised and continuous ventilation added house will achieve very acceptable levels of comfort and health; and as a consequence, also the energy efficiency will significantly improve.
The modelling has been done in the Passive House Planning Package (PHPP) which is the most accurate to real-world performance outcomes modelling tool available.
