The implementation of the new Nationwide Home Energy Rating Scheme (NatHERS) Technical Note legislation will result in closer building assessments with property developers, builders, assessors and designers. The question is will the new legislation support or hamper the building process?

The Problem with Windows. 

Windows can have a drastic effect on the thermal performance of a building. Up to 40% of a home’s heat can be lost through conduction or radiation at the window, and up to 87% of its heat can enter through solar gain. This unwanted heat flow can be devastating for the energy efficiency of any project.

It is important that designers modify their designs in relation to the climate in which they are built in. In order for the occupants of a home to remain thermally comfortable, the design must work with the climate, not against it, decreasing the need to use heating and cooling systems.

What is a 6 Star Rating?

The National Construction Code (NCC formally known as the BCA) requires all new residential dwellings in Australia (Except NSW)* to achieve a minimum of a 6 Star Rating using the Nationwide House Energy Rating Scheme (NatHERS), approved software.
