A NatHERS star rating depends on how much cooling or heating a 'standard family' (the occupants) may need to stay comfortable during a typical year. NatHERS accredited computer software simulates how heat enters and escapes a house every hour of every day of the year, assuming the occupants open and close windows and any blinds or awnings to make best use of the local climate.

Have you ever wondered why some houses are warm in winter when the heater isn’t on? Or how the same house stays cool in summer, without the need for an air-conditioner? The design of your home, from the building materials and layout, to the positioning of windows and shading, affect how well the home responds to the climate where it is located, how comfortable the home is to live in, and the amount of money you spend on heating and cooling.
All new Australian homes, or those undergoing major renovations, must meet minimum state and territory energy efficiency requirements based on the National Construction Code. The most common way to meet these requirements is by getting a home energy rating done using the Nationwide House Energy Rating Scheme (NatHERS). NatHERS software tools provide homes with a star rating out of ten based on how energy efficient they are—the more stars, the more energy efficient and the more money you save on energy bills.
Using software based on scientific research by the CSIRO, NatHERS estimates how much energy your home will need for heating and cooling by looking at: the layout of the home; the construction of its roof, walls, windows and floor; the orientation of windows and shading to the sun's path and local breezes; and how well these suit the local climate.
A zero star rating means the building shell does practically nothing to reduce the discomfort of hot or cold weather. A six star rating indicates good, but not outstanding, thermal performance, and a 10 star rated home is unlikely to need much, or any, mechanical cooling or heating (from appliances).
Different star ratings: The NatHERS star rating system refers to your home’s construction and design features, and is different to the star rating of appliances. Your fridge, dishwasher, air-conditioner and other household appliances are rated under the Greenhouse and Energy Minimum Standards (GEMS), and are not measured as part of the NatHERS star rating.
How we do it
We take pride on our clients as we have interacted with a very wide range of endeavours since September 2009. We have had excellent and ongoing relationship with over half of our current clients and business has been growing at a steady pace of 25% on average per annum. A large proportion of our current dealings arises by new clients that have already had BASIX/NatHERS completed by other consultancy firms.
Ensure that you will have a reliable company on your side all the way until the building is approved and in cases that our skills can be applied until the completion stage, by all means make sure that you contact us.
We are 100% committed to our clients. See for yourself!
Each zone is modelled separately for each dwelling we are working on. The chart on the left, shows heating loads per zone and the total heating consumption in Mj/annum.
This feature allows us to optimize very effectively thus saving you money via preventing the over specification of windows mainly, without reason throughout the dwelling. Instead, we know exactly which zone, underperforms and corrections are can be customized very accurately.
Here we can see for the same dwelling, in summer the cooling energy requirements in the KLD zone are responsible for 48% of the total dwelling requirements. So this zone needs either darker windows, or eaves, or ext. louvres, blinds etc, while the other areas do not have any special needs.
In this chart we see the combined heating and cooling contribution of each zone.
