The Nationwide House Energy Rating Scheme (NatHERS) evaluates the thermal performance and overall energy efficiency of new homes and apartments across Australia. Working with a qualified NatHERS consultant helps your design meet the National Construction Code (NCC) requirements, which from 2022 mandate a minimum 7-star Thermal Rating and a Whole of Home score of 60 for houses and 50 for apartments.<\/p>

A NatHERS energy assessment helps architects, builders, and homeowners optimise designs, select efficient appliances, and enhance occupant comfort while reducing long-term energy use. With around 90 percent of new dwelling designs now assessed through NatHERS, these standards support both compliance and cost savings, with updated NCC requirements helping new homeowners save an average of $183 annually.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

A NatHERS certificate is an official assessment that measures how energy-efficient a new home or apartment is. Instead of relying on complex building rules, NatHERS assessors use computer modelling to estimate how much energy the dwelling will need for heating, cooling, appliances, and on-site energy systems. This makes it easier for designers and builders to understand where improvements can be made for comfort and efficiency.<\/p>

For homeowners, a higher NatHERS rating means lower energy bills, better indoor comfort, and a home aligned with Australia\u2019s sustainability goals. Importantly, achieving a minimum 7-star rating can also qualify homeowners for green loans from selected insurers and lenders.<\/p>

Thermal Star Rating<\/strong><\/h3>

The Thermal Star Rating scores a home from 0 to 10 based on how well it maintains comfortable temperatures without relying heavily on heating or cooling. Factors such as layout, insulation, window design, and orientation affect the score. A 7-star home performs efficiently, while 8 to 10 stars indicate exceptional energy performance. This rating supports smarter, energy-efficient home design and aligns with NCC requirements.<\/p>

The Whole of Home Rating<\/strong><\/h3>

The Whole-of-Home rating evaluates the energy use of major appliances, including heating and cooling systems, hot water, cooking loads, plug loads, and any on-site solar or battery storage. Scored out of 100, it shows whether a dwelling meets or exceeds the NCC energy budget. This broader assessment helps homeowners understand the total impact of their appliance choices and supports more sustainable performance across the entire home.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

At our NatHERS Assessment Services, we follow a thorough step-by-step process to offer accurate and reliable energy efficiency evaluations for buildings.<\/span><\/p>

Step-by-Step Guide<\/p>

  1. Initial Consultation<\/b><\/h3>

    We begin with a consultation to understand your project requirements and goals. This includes discussing your design plans and any specific energy efficiency targets.<\/span><\/p><\/li>

  2. Documentation Review<\/b><\/h3>

    Our assessors review the plans, specifications, and any relevant documentation, which helps us gather the necessary information for the assessment. In addition, if the information or specific details to undertake a detailed assessment are not available or have not yet been made, default settings have been developed to be used in these situations.<\/span><\/p><\/li>

  3. Energy Modelling<\/b><\/h3>

    We use software tools to simulate the building’s thermal performance. This involves inputting data and other essential details into the assessment software.\u00a0<\/span><\/p><\/li>

  4. Rating Calculation<\/b><\/h3>

    The simulation generates a star rating under the NatHERS framework. Our assessors analyse the results and identify opportunities for improvement if the initial rating does not meet the desired standards.<\/span><\/p><\/li>

  5. Certification<\/b><\/h3>

    Upon completing the assessment and making any necessary modifications, we issue the NatHERS Certificate with the logo, confirming the building’s energy efficiency rating.<\/span><\/p><\/li><\/ol>

    At Afogreen Build, our assessors use NatHERS-accredited software tools to generate official star ratings and issue relevant certificates.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    NatHERS star ratings are generated using sophisticated thermal performance modelling. In simple terms, accredited NatHERS software analyses the building\u2019s design, construction materials, orientation, and climate zone. The software then simulates how much heating and cooling the home will need throughout the year.<\/p>

    Based on these simulations, the home is assigned a star rating. A lower rating means the home requires more energy to stay comfortable, while a higher rating reflects efficient design with minimal heating and cooling demand. Working with a NatHERS consultant helps these simulations are interpreted accurately, allowing homeowners and designers make informed decisions that support energy-efficient home design and long-term sustainability.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    IMPROVING YOUR DESIGN TO ACHIEVE HIGHER STAR RATINGS<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
    \n\t\t\t\t
    \n\t\t\t\t\t\t\t\t\t

    Even small design improvements can significantly increase a home’s NatHERS star rating. Upgrading insulation, choosing better wall construction methods, improving window glazing, and incorporating effective shading all reduce the amount of energy required for heating and cooling. These changes enhance thermal performance and help achieve better results.<\/p>

    At Afogreen Build, our NatHERS consultants provide tailored recommendations based on your home\u2019s climate zone, site conditions, and construction approach. By modelling different design scenarios, we help homeowners, architects, and builders refine their plans to reach 7-star performance or higher, aligning each project with modern expectations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
