NatHERS assessments & star ratings for energy-efficient homes in NSW

The Nationwide House Energy Rating Scheme (NatHERS) is the government-backed standard for measuring your home’s thermal efficiency. With a rating system that runs from zero to ten stars, higher scores mean better comfort, lower running costs, and full compliance with the National Construction Code

Why Do You Need a NatHERS Assessment?

1. Building approval compliance
   Many Australian states — including NSW — require a NatHERS assessment to meet the energy efficiency standards in the National Construction Code (NCC).
2. Lower Energy Bills
   High-star ratings reflect better thermal design, helping you rely less on artificial heating and cooling.
3. Year-round comfort
   A well-rated home stays warmer in winter and cooler in summer — naturally.
4. Reduced environmental impact
   Efficient thermal performance means lower energy use and fewer carbon emissions.
5. Market appeal and resale value
   Homes with strong energy ratings are increasingly attractive to buyers seeking long-term savings and comfort.

When should you get a NatHERS assessment?

The best time to arrange your NatHERS assessment is during the design stage — before construction begins. That way you can optimise your plans early, with guidance on glazing, shading, insulation, orientation and materials to boost thermal performance before it’s too late.

How our NatHERS assessments work

1. You share your architectural plans and site details – We gather critical info, including floor plans, materials, orientation, glazing and site location.
2. We run a thermal simulation using accredited NatHERS software – As accredited NatHERS assessors, we analyse your home’s thermal performance in your local climate.
3. You receive your NatHERS certificate and design recommendations – This includes your final star rating plus practical advice to elevate performance for smooth approvals
