In the field of ESD, two terms which constantly appear are the U and R values of products, but what do these mean? Whether referring to insulation or glazing each product on the market has a specific either U or R value. These values refer to the thermal performance of specific products and materials and how they assist in maintaining thermal control in a building or structure. These values are an integral part of the BASIX, NatHERS and Section J process in the NCC, which require specific values to be either entered into the glazing calculator for Section J reports or specific glazing types with predetermined U and SHGC values for BASIX and NatHERS along with specific R values for insulation and building materiality.

The NCC sets a minimum acceptable thermal performance for residential dwellings by specifying a minimum 6 star rating for all new projects in Australia with the exception of NSW who are under the BASIX programme.

6 Design Tips for a 6 Star NatHERS Energy Rating

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.

One of our most frequent requests from our clients is to reduce or remove the requirements of double glazing on their projects. Double Glazing can cost up to twice the amount of single glazing and on some projects it can tip the feasibility scales. Every year it seems the ever improving Energy Efficiency - Section J of the National Construction Code and the National Thermal Comfort (NatHERS) regulations are making it increasingly difficult to avoid specifying double glazing. However, at Certified Energy we have 5 tried and true tips that will go a long way to avoid specifying double glazing on your next project.

You might be in a hurry when you are looking for your NatHERS assessment. But be aware of choosing too fast and ending up with an Assessor that will take their time. We have written down 4 tips we think you should know before choosing your NatHERS Assessor.

NSW BASIX Regulation Update for Architects:

The Evidence of Suitability method using the Deemed to Satisfy Provisions of Part J of the Energy Efficiency section of the NCC Volume 1 (formally the BCA) have been chosen as the most appropriate method to assess the compliance of the proposed development.
