Sustainable Building: Innovation Needed in Australia

For most of the last two decades, sustainability in Australian construction was a differentiator. A manufacturer could arrive with a good environmental story, win goodwill with a design team, and compete on the same commercial terms as everyone else. That period is ending, and it is ending unevenly, which is what makes it difficult to plan for.

Sustainability requirements now reach a building product through three separate doors, and they ask for completely different things.

Three doors, three kinds of evidence

Regulation sets a floor. The National Construction Code establishes minimum performance, and a product either helps a building meet it or does not. This is the door most manufacturers understand, because it works like the compliance regime they already deal with at home.

Voluntary rating schemes sit above the floor. Green Star and NABERS are the ones that shape specification on commercial projects, and they operate on a logic that catches many entrants out: they do not reward a product for being good. They reward a product for being verifiably documented in a format the rating tool can consume. A genuinely superior product with no third party verified data is worth close to nothing inside a rating submission.

Client procurement policy is the fastest moving of the three and the least visible from offshore. Government departments, institutional developers and large corporate tenants increasingly write environmental requirements directly into tender documents. These are contractual rather than regulatory, they change without any public consultation process, and they are frequently more demanding than either of the other two doors.

The Environmental Product Declaration is a gate, not a brochure

The single most common mistake we see is treating an Environmental Product Declaration as a marketing asset. It is not. It is a piece of infrastructure, and increasingly it is a precondition for being considered at all.

An EPD is a third party verified statement of a product’s environmental performance across its life cycle, prepared to a recognised standard and independently reviewed. What matters commercially is not that it says something flattering. What matters is that it exists, that it is current, and that its declared unit and system boundary match what the assessor needs.

Manufacturers regularly arrive with an EPD prepared for their home market and discover it is not usable here, for reasons that have nothing to do with product quality: the wrong programme operator, a system boundary that excludes transport to a market on the other side of the world, or a declared unit that does not match how the product is specified locally. Shipping a product 15,000 kilometres materially changes its embodied carbon figure, and an EPD that ignores that stage will be challenged by anyone doing the assessment carefully.

Embodied carbon is moving from voluntary to contractual

Operational energy has been regulated for years. Embodied carbon, the emissions locked into the materials themselves, has largely not been. That is changing through procurement rather than through the Code, which means it is arriving faster and with less warning than a regulatory change would.

For a manufacturer, this has a specific practical consequence. Whole-of-building assessments need product-level data. If your data does not exist in a usable form, the assessor substitutes a generic industry average, and generic averages are almost always worse than a real product’s actual performance. You are then penalised for the absence of documentation rather than for the product.

What we would prepare, in order

• A current EPD with a defensible system boundary that accounts for transport to this market rather than pretending it does not happen.
• Data in the formats assessors actually use, so a consultant can drop your product into a model without contacting you and waiting three days for an answer.
• Clarity about what your product does not claim. Overstated environmental claims attract regulatory attention in Australia, and a specifier who finds one overstatement will discount everything else you have said.
• A position on end of life. Recyclability, disassembly and take-back are increasingly asked about directly, and “we have not considered that” is an answer that gets remembered.

Why this is an opportunity rather than a burden

The manufacturers who struggle with this are the ones who treat it as a compliance cost to be minimised. The ones who do well treat it as a barrier to entry that works in their favour once they are over it.

Most of your competitors in a given category will have incomplete data. Being the supplier whose numbers are verified, current and easy for a consultant to use makes you the path of least resistance on a rating submission. In a market where specifiers are professionally accountable for what they name, being easy to defend is worth more than being marginally better.
