Building Thermal Performance Assessing explained:

A building thermal performance assessment also known as a House Energy Rating makes it easier to boost the environmental performance of new house designs and ensure compliance with the appropriate sustainability regulation or assessment scheme.

BERS Pro is a software package that is federally developed and approved to rate the thermal performance of residential dwellings in Australia.

Building details are entered from plans into the software to obtain heating and cooling energy levels that will be needed for a home to stay naturally cool in summer and warm in winter.

The building details entered into the BERS Pro software encompass all elements of the buildings construction, fabrication and dimensional layout. This process involves the placement of all the building elements directly onto a scaled background image of the floor plans. In this way all rooms on the plans are assigned their individual names and functions.

All elements of a dwelling are taken into account eg door and window positions, floor coverings and ventilation.
Once the assessment has been completed, the heating and cooling loads for individual rooms can be examined and more informed decisions can be made about the types of heating and cooling systems required, as well as the levels of insulation or glazing.

The software simulates the appropriate climate zone and orientation of the dwelling according to where it will be located, over 1 year of weather conditions, giving a complete picture of the heating and cooling required over a full years climate cycle.

Within the BERs Pro software package all the individual elements that make up the whole building structure have multiple choices for material selection available for simulation. For example, glazing options can be selected from current manufacturers specifications and different insulation layouts and options can be selected to maximise the overall thermal benefit.

This means a far greater thermal performance outcome can be achieved along with making the home cheaper to run by lowering overall heating and cooling loads, ready for BASIX compliance. The process of simulating using BERs Pro gives a more detailed assessment for the client, providing many more options to design with.
