Methods for calculations in “Smarter energy use: how to cut energy bills and climate harm”

Methods for calculations in “Smarter energy use: how to cut energy bills and climate harm” Note on the methods used to calculate bill savings, emissions reductions, and details of other assumptions. [...] The Smarter Energy Use: how to cut energy bills & climate harm report analysis relies on established methods for assessing the cost of a range of appliances and savings from efficiency upgrades. [...] 1 Gas appliance switching savings Bill savings related to switching out gas appliances for efficient electric options were the same as those used in the previous Climate Council report ‘Switch and Save’ and can be found here. [...] Energy efficiency upgrade savings Bill savings for energy efficiency upgrades were calculated by applying average reductions in heating and cooling load from previous analyses to NatHERS 1.5 Star rated homes of 186m2 in capital cities. [...] Heating and cooling is assumed to be performed by a Reverse Cycle Air Conditioner with a Coefficient of Performance of 3.19- the average CoP across all rated air conditioners in Australia.2 The heating and cooling required is then multiplied by the average electricity prices in capital cities.
