Green Star and NABERS: where office furniture actually earns points

Green Star office furniture questions usually arrive in the wrong order. The short answer is that one Australian rating scores the furniture and the others do not. Green Star Fitouts v1, released on 18 March 2026, carries a credit named Responsible furniture, and from 1 October 2026 it is the only tool a new fitout project can register under. Green Star Buildings rates the base build, spreads its Responsible Products credits across four building layers, and excludes loose furniture from the finishes calculation entirely. NABERS rates measured operating performance and does not assess products at all. This post sets out which document says what, and what a furniture package has to produce to count.

Three ratings, and only one of them scores a chair

The confusion is reasonable, because all three ratings turn up on the same project and two of them use the word responsible. The distinction that matters is what each one is actually rating: a building, a fitout, or twelve months of measured operation.

The three Australian ratings a furniture package runs into, and whether the furniture scores in each

Rating	What it rates	When it applies	Does loose furniture score
Green Star Fitouts v1	Design and construction of a new fitout	Registration, through to a design and as built submission	Yes. The Responsible category carries a credit named Responsible furniture
Green Star Buildings v1	Design and construction of a new building	Base build, before a tenant is in it	No. The Apartments Pathway states that loose furniture is not included in the finishes package calculation
Green Star Interiors	Fitout, superseded tool	Closed to new registration on 30 September 2026	Registered projects continue under their approved timelines
NABERS	Measured operational performance of a building in use	Annually, after twelve months of operation	No. None of the five NABERS ratings assess a product

That last row is the one that saves the most time in a meeting. A tenant chasing a 5 Star NABERS Energy rating has no furniture obligation arising from it, because NABERS has no product scope. A tenant chasing a Green Star Fitouts rating has a furniture obligation that starts at tender, not at delivery.

What changed on 1 October 2026

The tool the fitout industry had used was Green Star Interiors. GBCA states on its Green Star Fitouts development page that "Green Star Fitouts replaces the previous rating tool, Green Star Interiors", that "Green Star Interiors remains open for registration until 30 September 2026", and that "From 1 October 2026 all new fitout projects must register under Green Star Fitouts". Projects already registered under Interiors may continue under their approved timelines, and GBCA states that an Interiors project can move across at no additional cost.

For a specifier the practical effect is that a fitout registered this month is being assessed against a credit set that did not exist two years ago, and a furniture schedule written against the old habits will be short of evidence. The reasoning GBCA gives for the new tool is published on the overview page: fitouts account for 32 per cent of a commercial office building's lifecycle emissions, the average commercial fitout generates 368.6 tonnes of waste, and interiors are replaced every five to seven years.

Announcing the tool on 18 March 2026, GBCA Chief Executive Officer Davina Rooney said of fitouts that "Green Star Fitouts is designed to break that cycle by embedding circularity into how fitouts are planned from day one". The first project certified under the tool came through the Early Access Program, led by Dexus for the Clean Energy Finance Corporation with Woods Bagot, applying Dexus's Forever Fitout approach. Andy Collins, Executive General Manager, Office at Dexus, said that "Green Star Fitouts provides an important, credible framework to measure and verify these outcomes".

Where furniture sits in the Green Star Fitouts credit set

Green Star Fitouts v1 organises its credits into six categories. Furniture is named in one credit outright and is reachable through several others, which is the part that gets missed when a schedule is written to chase a single credit.

Green Star Fitouts v1 credits in four of its six categories, as published on the tool overview

Category	Credits
Responsible	Industry development; Responsible building selection; Responsible fitout delivery; Responsible handover; Responsible procurement; Responsible finishes and joinery; Responsible partitions; Responsible furniture; Responsible equipment and fixtures
Circular	Maximising reuse; Enabling multiple uses; Enabling long life; Enabling future reuse; Circularity Measurement
Healthy	Clean air; Light quality; Acoustic comfort; Low toxin materials; Ergonomics; Connection to nature; Thermal comfort; Amenity and comfort
Positive	Fully Electric; Powered by renewables; Energy efficient; Water efficient; Upfront carbon reduction; Upfront carbon compensation

Read down the Circular column and the furniture implications are obvious even without the criteria in front of you. Maximising reuse rewards keeping what is already on the floor. Enabling multiple uses rewards a setting that does more than one job. Enabling long life and Enabling future reuse reward a piece that can be repaired, re-upholstered, dismantled and sold or redeployed rather than skipped. In the Healthy category, Ergonomics and Low toxin materials both land on seating and worksurfaces.

The rating thresholds are published: a 4 Star rating is described as Best Practice and requires the Minimum Expectations; 5 Star, Australian Excellence, requires the Minimum Expectations, the Climate Positive Pathway and 20 points; 6 Star, World Leadership, requires the same plus 45 points.

Why Green Star Buildings stops short of the furniture

Green Star Buildings handles products through four Responsible Products credits, and GBCA's guidance on Responsible Products credits defines each layer: Responsible Structure for load bearing and stability components, Responsible Envelope for the external shell and its components, Responsible Systems for active systems such as mechanical, hydraulic, transportation, electrical and ventilation, and Responsible Finishes for internal finishes such as flooring, plasterboard, paints, ceilings, partitions, doors and internal windows.

Furniture is not one of the four. The Green Star Buildings Apartments Pathway document, version 1 revision A dated 24 February 2025, makes the exclusion explicit where it defines the finishes package: internal finishes include flooring, plasterboard, paints, ceilings, partitions, doors, internal windows or similar, joinery used as part of a wall finish may be counted, and "Loose furniture is not included". Fixed joinery that forms part of a partition is in. The chairs in front of it are not.

The thresholds each layer has to hit are worth having in one place, because the Finishes row is the one a furniture supplier is most often asked about by a project team that has not yet worked out furniture is outside it.

Responsible Products thresholds in Green Star Buildings, by building layer, from the GBCA Responsible Products fact sheet

Building layer	Good practice, credit achievement	Best practice, exceptional performance	Good practice, exceptional performance
Responsible Structure	50% of products, minimum RPV 10	10% of products, minimum RPV 15	80% of products, minimum RPV 10
Responsible Envelope	30% of products, minimum RPV 10	10% of products, minimum RPV 15	60% of products, minimum RPV 10
Responsible Systems	20% of products, minimum RPV 6	5% of products, minimum RPV 11	35% of products, minimum RPV 6
Responsible Finishes	40% of products, minimum RPV 7	10% of products, RPV 12	60% of products, minimum RPV 7

Those figures come from GBCA's Responsible Products Leadership Challenge fact sheet, which also sets out that the Leadership Challenge is worth 4 points, one per Responsible Products credit. The Apartments Pathway document confirms the Finishes position in its own credit: 40 per cent of finishes in each scheme package by cost at a Responsible Products Value of at least 7, or a prescriptive route where all carpet, paint and timber products meet a Responsible Products Value of at least 7.

How a Responsible Products Value is built, with a chair as the worked example

A Responsible Products Value is not a rating a project team calculates. GBCA's Responsible Products Framework describes initiatives completing a self assessment that aligns their standards criteria and governance processes against the Responsible Product Guidelines, after which they are assigned a Responsible Product Value. The greater the value, the more closely they align with the guidelines. Examples of recognised initiatives GBCA gives are industry wide environmental product declarations, product specific environmental product declarations, ISO 14001 certification, Climate Active Carbon Neutral Certification, chain of custody certification and third party product certification schemes. Which of those claims are worth asking a supplier for, and which are self declared, is the subject of sustainable office furniture: which claims hold up on a schedule.

The useful part for anyone specifying furniture is how GBCA handles an item whose components do not all comply, because the worked example it publishes is a chair. The item is broken into the key major components, approximately those making up 80 per cent of its mass, each is assigned a value, and the values are weighted by the component share.

The worked example GBCA publishes for a chair, where only some components carry a Responsible Products Value

Component	Share of the item	Component RPV	Contribution
Timber	60%	10	6
Foam	20%	0	0
Fabric	20%	12	2.4
Chair, total	100%		8.4

Two things follow from that arithmetic and both are useful at tender. The first is that an uncertified component does not disqualify the item, it dilutes it: the foam at zero costs the chair 2 points out of a possible 12 or so, not the whole score. The second is that mass is the weighting, not cost or visual prominence, so a heavy certified timber frame carries a chair further than a certified fabric does. Where the timber certification itself comes from, and what Australia's own rules now demand of imported timber furniture, is set out in timber chain of custody on a furniture package.

Compliance is then measured by cost, not by item count. The Apartments Pathway document allows cost to be calculated either as total cost, meaning materials plus labour, or as materials only, provided the basis is consistent across the numerator and the denominator.

The evidence a furniture package has to produce

This is where fitout projects lose points they had already earned. GBCA's guidance sets out exactly what an assessor checks on a manually added product: that the certificate matches the product added to the calculator, that the certificate was valid at the time of procurement, with the end date checked, that it matches the product certification initiative selected in the calculator, and that it includes a certificate number. Receipts must be attached to each compliant product, and a subcontractor confirmation of purchase price is deemed acceptable.

Where a product straddles two layers, the guidance allows it to be entered in more than one, with the cost split across them and the split noted in the submission. That is the clause a freestanding pod, a full height storage wall or a demountable partition run usually ends up relying on.

What the Circular credits ask a piece of furniture to be

The criteria behind each Circular credit sit in the submission guidelines on the GBCA resources portal and are not public, so what follows is about product characteristics rather than point counts. The credit names, though, are enough to tell a specifier what sort of evidence to start collecting, and three products Geneva supplies illustrate the three different answers.

EONA from Thinking Works is the clearest case for Enabling future reuse. Thinking Works publishes legs made from 100 per cent post consumer recycled aluminium, a system that comes apart completely for recycling, leg stances and three leg angles at 0, 22.5 and 45 degrees that can be changed after installation, and a Life Cycle Assessment it commissioned of the materials. The name is an argument in itself: EONA stands for Everything Old Is New Again.

Okidoki XL Folding answers Enabling multiple uses. Published tops run from 900 to 2600 mm wide and 900 to 1200 mm deep at 725 mm high across five frame sizes, the frame folds flat and nests on castors, table links are supplied with every folding frame so a run can be joined and separated again, and the frame carries 80 kg including the worktop. A training room that can become an all hands space and go back again in an hour is a reuse argument that does not depend on anybody buying anything.

Merano from TON answers Enabling long life. It is a solid wood stacking chair, made in beech, oak or American walnut, and TON publishes the side chair as stacking five high on the floor and fourteen on its trolley. Stacking is the quiet circularity feature, because a chair that can be stored compactly and brought back out is a chair a tenant redeploys rather than skips at the end of a lease. The broader table and seating ranges carry the same logic in different proportions.

What this changes on a furniture schedule

Four changes, in the order they bite. Establish which tool the project is registered under before the furniture schedule is priced, because Green Star Fitouts puts furniture in scope and Green Star Buildings does not. Ask for certificates at quotation, with numbers and expiry dates, not at delivery. Record the cost basis you are using and keep it consistent, because the calculation is a percentage of cost and a mixed basis will not reconcile. And treat reuse as a specification decision rather than a sustainability gesture, because the Circular credits reward the floor that kept its tables far more reliably than the floor that bought better ones.

One thing worth saying to any project team: furniture sitting outside Green Star Buildings is not the same as furniture not mattering. It means the base build rating will not capture it, and the fitout rating will. The waste side of the same question, including what the strip out produces and who is responsible for it, is covered in what the furniture delivery leaves behind, and the procurement route a government or institutional client has to follow is in government furniture procurement: what a panel does not settle.

What we could not verify

The criteria for the Responsible furniture credit itself, meaning the points available, the percentage of the furniture package by cost and the minimum Responsible Products Value it requires, are published in the Green Star Fitouts submission guidelines on the GBCA Green Star resources portal, which needs a GBCA account. The credit name and its category are published openly on the tool overview; the numbers are not, and they are not reproduced here or guessed at. The same applies to every other Fitouts credit named in this post. The Responsible Products Values held by any particular furniture certification are held in GBCA's Responsible Products score checker, which is queried product by product, so no value for any specific product or scheme is quoted here. Finally, the thresholds in the Green Star Buildings table are taken from a GBCA fact sheet dated 16 December 2021 and confirmed for the Finishes layer against the 24 February 2025 Apartments Pathway document; the other three layers were not re-confirmed against a 2025 or later source.

Geneva supplies the tables, workstation systems and seating that these credits land on, and the manufacturers behind them are the ones who hold the certificates a submission needs. If you have a fitout registered under Green Star Fitouts and you want to know which items on the furniture schedule can produce a current certificate and which cannot, send us the schedule and we will go back to the manufacturers and tell you what is actually documented.
