An energy rating report, also known as thermal performance assessment, provides a calculated measure of the heating & cooling loads for a dwelling/building. A thermal performance assessment allows the input of design & building envelope data such as, orientation of the dwelling, external wall materials, roof types, ceiling heights, window types & glazing values etc. All of this information is collated & factored into the complete performance of a dwelling’s/building's heating & cooling loads which results into the star rating. The star rating denotes the ability for a dwelling/building to maintain comfortable indoor temperatures without the excessive use of mechanical heating & cooling units therefore reducing energy usage. The minimum requirement for any new dwelling is no less than 7 stars. Any other development types may have different requirements, which we'd discuss with you.

Whole of home?​​

​

The Whole of Home assessment is a separate rating from the NatHERS thermal star rating.. It provides an indication of a home's overall energy performance, including estimated energy use, running costs, and associated greenhouse gas emissions.

A Whole of Home rating considers:

• Hot water, heating and cooling systems

• Lighting, cooking and plug-in appliances

• Pool and spa equipment (where applicable)

• On-site renewable energy generation, such as solar photovoltaic systems, and battery storag

​

The rating scale generally ranges from 0 to 100, where a score of 100 represents a net zero energy home. However, ratings above 100 are possible. This can occur when a home generates more energy than it consumes, for example through a larger-than-average solar energy system combined with other energy-efficient features.

One small clarification: a score of 100 represents a net zero annual energy use outcome under the Whole of Home methodology, while scores above 100 indicate a net energy-positive home that exports more energy than it uses over a year.

​

The minimum benchmark is 60 for compliance to be met & is usually achievable by including solar panels.

​

Why are they required?

​

When building or renovating in order for your building surveyor to grant your building permit, they will most likely advise that you're required to obtain a thermal performance assessment (energy rating report) & whole of home certificate.

Why? Thermal performance assessments & whole of home are required as per the National Construction Code (NCC) & stipulate that the objective is ‘to reduce greenhouse gas emissions by efficiently using energy throughout the life of the building’, it’s that simple!
