It is a requirement for new Australian residential buildings to be designed and built to meet a minimum level of thermal performance.  

A House Energy Rating is a measure on a scale from 0 stars to 10 stars which corresponds to the average amount of energy required to keep the rooms in the dwelling at a comfortable temperature.  

The minimum star requirement for new buildings is governed by the Australian NCC (National Construction Code)  

Energy Imaging are experienced at conducting Thermal Performance Assessments on your design and are accredited by ABSA (Association of Building Sustainability Assessors)

We use the modelling software 'FirstRate5' to assess your design.  This software is one of three software packages approved for use under the Nationwide House Energy Rating Scheme (NatHERS), and Energy Imaging offer the services of a trained and experienced accredited assessor.   

The modelling takes into account multiple factors which affect the building's thermal performance such as climatic zone, location, orientation on the block, room layout including window location and size, construction materials, and occupant behaviour.  These factors are covered in more detail on the NatHERS website.
