The estimated upfront costs, potential energy bill reductions, and impacts on carbon
emissions, provided by Cogo’s Home Energy Efficiency Tool, are based on a typical Australian
property with the attributes that you have selected (e.g. occupancy, type of property,
heating systems, etc.) and aren’t specific to your individual home. Actual outcomes may
differ to the estimates from this tool and you may not realise the actual savings from
making the suggested upgrades stated in this tool.
In calculating these estimates, Cogo draws on the best available Australian data, including
Government home energy use studies, publicly available energy prices, and industry leading
research on home energy generation and demand. The estimates are updated as new data becomes
available and Cogo is responsible for the accuracy and completeness of these estimates.
Energy costs are, in almost all cases, based on the average price of energy offers of the
top 20 suppliers in the state.
The same average energy price is assumed for all upgrades. For the solar and solar+battery
upgrade, the average feed-in-tariff price is also included.
The number of people in your household impacts on two key variables:
-
Estimated floor area of your home, which in turn determines the room heating and cooling
energy demand; and
-
Estimated amount of energy used for hot water heating and cooking (i.e. the more people
in the house, the more showers and cooking needed.)
Typical costs are based on two key factors:
-
Actual installation costs of heat pumps in your state over the last 12 months; and
-
Estimated floor area of your home, including assumption of conditioned and unconditioned
areas from CSIRO data (the larger a home, the bigger, and more expensive, the heat pump
required.)
Given energy bill reductions and installation cost estimates are generated from average
data, you need to consider whether the information provided by this tool is suitable for
your situation and your circumstances.
