NatHERS Assessment

6 star energy report | Nathers

NatHERS is an acronym for Nationwide House Energy Rating Scheme. It is a star rating system (out of ten) that rates the energy efficiency of you home, based on its design. The energy rating is typically done during the design stage but can also be done retrospectively if the right information is available. 

NatHERS is recognised by the National Construction Code (NCC) as an available mechanism to determining if a building is complaint to the energy efficiency measures of the code. It is particularly useful as it is a whole of building assessment allowing you to offset savings in one place against shortcoming in other places to get an overall complaint result. 

This is a good tool when you have particular constraints such as a particular roof colour or type of window you would like to use. Sometimes these aesthetic desires can have a negative impact on the outcome of the efficiency of the building or, it could be as simple as it’s cheaper to add more insulation to a wall than having high performance windows.  NatHERS allows you to offset these deficiencies with over performance in other places. Our team can help you determine strategies to work within your constraints. 


Completing a NatHERS assessment during the design stage is particularly useful for not only ensuring you meet the requirements of the National Construction Code (NCC) but it is also a useful tool when selling a house or purchasing a house to determine how efficient the house will be. As a house is the single biggest investment most people will make in their life time, why not ensure its the most efficient investment in your lifetime too?
