  • Section J


    What is a Section J Report?

    A Section J Report is an Energy Efficiency Report required for all new Class 3-9 buildings to ensure compliance with the National Construction Code (NCC).

    When are they required?

    Section J Reports are required by councils and PCA’s at CC Stage. We would recommend engaging us as early as possible at DA Stage so that we can identify any possible non-compliances based on early design, therefore reducing compliance risk, identifying costs ensuring effective time management.

    What does a Section J cover?

    The Section J Report takes the DTS (deemed to satisfy) route to compliance. It is designed so that all new buildings will meet minimum requirements for thermal comfort and greenhouse gas emissions.

    The main passive design elements of a Section J Report cover:

    • J1 - Building Fabric
      Our report will provide you with detailed tables of your total system R-values for walls, floor and roofs located on your developments thermal envelope.
    • J2 - Glazing
      For the glazing specifications we will complete the ABCB glazing calculator and determine your total system U-values and SHGC’s for your glazing.
      NB - Refer to JV3 Alternative/Performance Solution to reduce the thermal specification of windows or rationalise to one specification throughout.
    • J3 - Building Sealing
      We will provide detailing on building sealing, where it is required and what can be done to meet compliance.

    Section J - JV3


    What is a JV3 Report?

    The Section J, JV3 Performance Solution is the alternative or performance pathway to compliance with Section J of the NCC.

    The JV3 is generated from a bespoke computer simulation for each development. We use an approved software called IES VE.

    When are they required?

    Section J, JV3 reports are required by councils and PCA’s at CC Stage.

    What does a JV3 cover?

    The JV3 uses the verification method approach and involves holistic modelling of the building/development to incorporate:

    • thermal mass of buildings;
    • profiles for usage patterns;
    • internal heat gains (appliances, solar, lighting, people etc);
    • dynamic topographic solar shading analysis;
    • air-conditioning design control;
    • uncontrolled infiltration;
    • solar absorptance for walls roofs;
    • occupants thermal comfort;
    • renewable energy (solar panels/photovoltaics)

    The JV3 alternative/performance solution is a great way to overcome some of the worst-case scenario calculations of the DTS glazing calculator, by considering the building/development more holistically and therefore reducing glazing thermal specifications which results in cost-savings for the build.

    The JV3 can also compensate by increasing the R-value’s of walls, roofs and more to offset the glazing specification and consider the benefit of on-site energy generation like PV’s.

  • BASIX Certification

    What is a BASIX Certificate?

    BASIX is a sustainability certificate in NSW that is required for Class 1 and Class 2 developments for both new builds and alterations/additions.

    When are they required?

    A BASIX is mandatory for all DA’s in NSW.

    What does a BASIX Certificate cover?

    A BASIX Certificate consists of three sections; Water, Thermal Comfort and Energy.


    • Star ratings of showerheads, toilets, taps, dishwashers, clothes washers and more (if applicable).
    • Requirements for a rainwater tank and volume (if applicable).
    • Types of plants, indigenous or non-native.

    Thermal Comfort:

    • Insulation R-values to walls, floors and roofs.
    • Glazing U-values and SHGC’s.


    • Hot water system types and star ratings.
    • Control of bathroom and laundry exhausts.
    • Air-Conditioning types and star ratings (if applicable).
    • Gas or electric cooktops/ovens.
    • Appliances such as dryers, clothes washers, dishwashers and star ratings (if applicable).
    • Solar panels (if applicable).

    We are proficient and accredited in the use of BersPro and FirstRate5 Softwares for thermal comfort calculation

    We provide a draft of the BASIX Certificate before the completion and certification.

  • NABERS/BEEC Ratings

    What is NABERS?

    NABERS is a government piloted initiative which looks at existing buildings by assessing the actual energy and water consumption and calculating a star rating.

    What is BEEC?

    The BEEC is a federal requirement. It consists of a NABERS Energy Rating and a TLA (Tenancy Lighting Assessment).

    When are they required?

    A BEEC is mandatory for all existing offices over 1000m2.

    What does a NABERS Cover?

    There are two NABERS ratings we provide which are the office and apartment building ratings.

    For NABERS offices, a base building, office rating or whole of building rating can be completed for both water and energy. The office rating considers three critical elements, which are NLA, office hours and energy/water consumption over the past rating period.

    NABERS has introduced a new rating for apartment buildings which considers energy/water usage, apartment numbers, car parking spaces, centrally air-conditioned units, lift serviced apartments and more, to determine a rating score.

    Different apartment buildings are not disadvantaged by having more services, rather they are benchmarked against other similar apartment buildings to provide an informative comparative analysis.

  • Lunch 'n' Learn

    We can provide lunch & learn presentations to numerous architectural firms in the following areas:

    • Section J Compliance;
    • BASIX Compliance;
    • NABERS Ratings;
    • Proposed changes to Section J of the NCC 2019; and/or
    • Introduction to Sustainability.
    If you want to know more, please get in contact via phone or email Contact Us
  • Compliance Statements

    As the energy efficiency industry is developing and becoming more specialised, Certifiers are looking at industry professionals to ensure compliance.

    We have provided numerous SJ and BASIX Compliance Statements whereby we complete site inspections and identify defects accordingly.

    We liaise directly with the builder and resolve any outstanding issues in a cost effective and timely manner to ensure compliance.

  • BESS Reports

    In Victoria SDA’s (Sustainable Design Assessments) and SMP’s (Sustainability Management Plans) are required to be submitted to council. A BESS Report (Built Environment Sustainability Scorecard) is used to show compliance with SDAs and SMPs.

    It uses nine set categories such as Management, Water, Energy, Stormwater and more to calculate sustainability.

    We can complete and submit BESS Reports to councils as required.


    WELL Building Standard is the premier standard for buildings, interior spaces and communities seeking to implement, validate and measure features that support and advance human health and wellness.

    WELL looks at eleven different criteria's ranging from air quality, water, nourishment, light, movement, thermal comfort, sound, materials, mind, community and innovations.

    Certain preconditions must be met to achieve a rating. These along with optimisations can achieve a higher rating.

    WELL has three different ratings which are Bronze, Gold and Platinum.

    NABERS Commitment Agreements

    A NABERS Commitment Agreement is at design stage whereby the developer enters into a commitment that the building, when it is finally operating after a year, will meet a certain star rating.

    This is required by Council, especially for large office buildings. Essentially an energy rating is performed on the building from design stage with all the M & E specs. This gives an energy output which gives it a projected star rating. After the building has been in use for a full year, a year worth of bills are collected for an official NABERS rating to be conducted. The actual rating must align with the NABERS Commitment Agreement Rating.


    Greenstar - Design As Built is the top end design rating tool used for sustainability in Australia.

    The rating basically looks at approximately 9 different categories running from water, energy, technology, indoor environment, materials, transport, greenhouse gas emissions and more.

    Different credits are awarded for the different categories. The credits are weighted. A total of 100 credits are available.

    The more credits achieved the higher your star rating, ranging from 0-6 Stars.
