Commercial Energy Efficiency Reports in Queensland
Need an energy efficiency report for a commercial project in Queensland?
From preliminary design advice to final Section J reporting and JV3 modelling, we help you work out what’s needed for building approval. Tell us about your project and the plans you have—we’ll confirm the scope and provide a fee proposal.
Request a fee proposal
Tell us the building use, Queensland project location and design stage, and whether you need preliminary advice, final documentation or both. Mention the drawings available; we can confirm how to share them when we scope the work.
Section J reports for commercial and non-residential projects
From a current sketch design to coordinated approval drawings, we can scope the work around your design stage. Your fee proposal sets out the assessment, information needed, deliverables and estimated time to undertake the work. We are Melbourne-based and serve Queensland projects.
A Section J report records how the assessed design addresses the applicable energy efficiency provisions of NCC Volume One. It is also often called a commercial energy efficiency report or Part J report. The name alone does not define what is included: the building use, work proposed and assessment pathway do.
Projects can include offices, warehouses with office areas, retail, healthcare and dental premises, aged-care buildings, motels and community facilities. We confirm the building classification rather than assume it from the project name. Mixed-use developments need the scope identified for each relevant part.
For a warehouse and office, show which spaces will be air-conditioned and how they connect. The office envelope and its separation from an unconditioned warehouse can matter to the assessment. An unconditioned storage area is not a reason to assume the whole project has no energy efficiency obligations.
What the assessment and report cover
We assess the elements relevant to your project and agreed scope. These can include building fabric and glazing, building sealing, air-conditioning and ventilation, lighting, heated water, energy monitoring and other applicable Section J provisions.
- The assessment basis: applicable NCC edition, building areas and pathway.
- The drawings, specifications and assumptions used in the assessment.
- Identified shortfalls and practical design or specification changes to address them.
- The assessment results and supporting calculations or modelling relevant to the selected method.
- Requirements and outstanding information the design team needs to carry into the coordinated documentation.
The report supports your building certifier’s assessment; it is not the building approval. Preliminary advice and final documentation are different stages, with different information needs.
DTS or JV3: choose the method around the design
Deemed-to-Satisfy assessment
A Deemed-to-Satisfy (DTS) assessment checks the design against the applicable prescriptive provisions. It can suit a design that meets those provisions without substantial changes. If a glazing or fabric check falls short, we identify the issue and consider whether a design change is practical before recommending modelling.
JV3 energy modelling
J1V3, commonly called JV3, is a Verification Method used to support a Performance Solution. It compares the proposed building with a reference building using the rules of the applicable NCC edition. It can be worth considering where glazing, shading or envelope constraints make DTS difficult. Modelling tests whether the design meets the requirements; it does not guarantee a pass or a cheaper specification.
A JV3 assessment does not automatically replace every Section J check. We identify what the modelling addresses and what still needs separate documentation. You do not need to choose DTS or JV3 before making an enquiry.
Early design advice or final approval-stage documentation?
Preliminary assessment and design advice
At sketch design or design development, we review the information available and flag energy efficiency risks while glazing, shading and construction choices can still change. The agreed scope may include a preliminary DTS review or design-stage modelling. Assumptions and missing inputs remain visible; preliminary advice is not a final compliance report.
Final assessment and report
For final assessment, the drawings, building fabric, glazing and relevant services information need to describe the design being assessed. We complete the agreed calculations or energy modelling and prepare the report from that information. If the design changes, the affected assessment may need review.
Tell us whether you need early advice, final documentation, or both. The fee proposal distinguishes the stages, the information needed for each and the allowance for revisions or responses to certifier queries. It also identifies work outside the quoted scope.
What to send for a fee proposal
Send what you have. An initial enquiry does not need a fully resolved specification. These details help us scope the assessment and identify the next information needed:
- Project location, building use, approximate floor area and building class if known.
- Current floor plans, roof plan and sections, with a north point and drawing revisions.
- Elevations or a window schedule showing glazing sizes and any known glass, frame and shading details.
- Available building fabric information: roof, wall and floor build-ups, insulation and relevant construction details.
- Which areas are conditioned, plus available mechanical, electrical and heated-water information.
- Design stage, intended approval programme and any specific energy efficiency request from the building certifier.
- Whether you want preliminary advice, final assessment and documentation, or a staged fee proposal.
If the class, pathway or specifications are not confirmed, say so. We can identify what is needed for the next stage rather than treat an assumption as a settled design decision.
Use the Queensland requirements that apply to your project
The applicable NCC edition, Queensland provisions, building class, climate zone and conditioned areas shape the assessment. We establish the assessment basis for your Queensland project before the detailed checks begin. For adoption dates and edition changes, see our Queensland NCC and Section J guide.
Questions before commissioning a report
Is a Part J report the same as an energy efficiency report?
Those terms are often used for Section J documentation on commercial projects. An energy efficiency report can also mean other work, so include the certifier’s request and the building use. We will confirm the assessment and documentation included in the fee proposal.
Does an unconditioned warehouse need the same assessment as an office?
Not necessarily. The building use, classification, conditioned spaces, envelope boundaries and services affect which provisions apply. A warehouse with an air-conditioned office should be scoped as the actual building, not as a single undifferentiated storage space.
How much will the report cost, and how long will it take?
The fee and programme depend on the size and complexity, available documentation, assessment pathway and stages required. We confirm the fee, deliverables and timeframe in the proposal. If you have a target date, include it so we can assess the programme before you commit.
Is this service for houses or mixed-use projects?
This page is for commercial and non-residential assessment work, not a household energy-rating enquiry. For mixed-use projects, include all uses and any known classifications so we can confirm the scope for the relevant parts, including commercial areas and apartment common areas where applicable.
