Homes are given an Energy Efficiency Rating (EER) based on the annual energy demand (heat required to be added in winter and removed in summer to keep the home comfortable) and we have interpreted that into running costs of a property in terms of energy consumption for cooling and heating. We offer the calculation of annual gas and electricity cost for heating and cooling energy consumption for a user-selected single-storey house size in Canberra on our website; including the option of all-electric home conditioning since July 2022.
The calculations are based on the prices published by ActewAGL, and users are able to input a preferred home size between 75 and 500m2 to compare the estimated energy costs of heating and cooling a home corresponding to an EER using appliances of varying energy rating.
Until now, we have only covered the Canberra region (and been indicative of other locations in the NCC Climate Zone 7 – Cool Temperate) and are about to update the matrix to reflect current gas and electricity prices; but we will then be working on the other 7 major cities’ calculations, so they will be added soon. We will announce when the other cities are ready with Melbourne being our first target.
