In 2006 the ABCB released the first energy efficiency performance requirements and deemed-to-satisfy provisions within the Building Code of Australia (BCA) in a bid to reduce greenhouse gas emissions within the built environment. The philosophy behind the adoption of the provisions are that an energy efficient building is likely to stay warmer in the winter and cooler in the summer and by improving the conditions within a building, occupants are less likely to utilise artificial heating and cooling services.
An energy efficiency assessment is formal evidence of a buildings performance to meet the energy efficiency standards of the BCA. Generally, an assessor will assess a buildings performance via the elemental provisions or complete a 6-star rating using an approved National Housing Energy Rating Software (NatHERS). Worksheets and calculators will be provided as part of an assessment.
As an example, an energy efficiency assessment on a residential dwelling will include the below components;
- Building Fabric
- External Glazing
- Building Sealing
- Air Movement
- Services
In addition to any new building containing a conditioned space, any alterations to the existing building envelope requires a further assessment to ensure construction meets the performance requirements.
