An EnergyRating or Thermal Efficiency star rating is an accurate indicator as to how much heating or cooling is necessary to keep your development at a level of thermal comfort. The energy rating generated by an accredited NatHERS assessor using licensed software (such as Bers Pro) indicates a dwelling’s efficiency in preserving energy. It does not however indicate the dwelling’s actual consumption of energy as that depends upon appliances installed, the way in which they are used and can be effected by extreme weather. By improving your energy rating you will require less energy to keep your dwelling comfortable and therefore provide lower energy expenses as well as a much healthier environment.

The possible 0 to 10 stars is a scale that indicates the energy efficiency of a dwelling. If a dwelling is rated 0 stars then it offers no insulation from the outside temperature, therefore it is greatly affected by the outside temperature offering no control of heat flow. Whereas a 10-star dwelling is able to maintain a comfortable inside temperature all year round no matter what the outside temperature. So the more stars a dwelling has the less energy it consumes, therefore reducing energy expenses.

Generally, no as NatHERS energy ratings are based on how well designed the dwelling will be. Appliances that are added to the building and are likely to be changed in the future are not taken into consideration.

Our careful consideration when simulating the thermal performance of your dwelling(s) will ensure that your energy rating delivers many benefits including:

• Accurate results
• Reduced energy expenses
• Reduced cost of complying with BASIX
• Increased property values
• Sustainable buildings
• Healthier living environments
