2026 NCC commercial fit-outs change the calculus entirely. For years, energy efficiency in commercial buildings was treated as a box to be ticked at the end of design — a compliance report confirming the building met the minimum. That framing no longer holds. With the National Construction Code 2025 adopted in Victoria from 1 May 2026, the most substantial changes in the entire code fall on commercial buildings, and they are significant enough to reshape how a fit-out or a new commercial project is conceived. For an asset owner, the smarter response is not to ask how to comply at lowest cost, but to recognise that a genuinely efficient building is a more valuable building.
This article sets out what has changed under NCC 2025 for commercial work, why the direction of travel favours all-electric design, and how to treat the new standards as an asset rather than a burden.
2026 NCC Commercial Fit-Outs: A Code Turned Towards Commercial Buildings
The previous edition of the code, NCC 2022, directed its major energy changes at housing. NCC 2025 reverses that emphasis. Residential requirements are largely held steady — building ministers have paused further residential energy changes for several years — while the commercial provisions, sitting in Section J of Volume One, have been tightened considerably. The changes apply to the commercial building classes: offices, retail, hotels, warehouses, healthcare and the like. Victoria adopted the new code from 1 May 2026, with projects that had not commenced design before that date generally required to work to the new standard. It lands alongside a broader regulatory reset — our guide to the VBA to BPC transition covers the other half of the picture.
The headline measures are worth understanding even at a high level, because they change how a building is planned rather than merely how it is documented.
What has actually changed
Several shifts stand out in the National Construction Code for anyone delivering commercial work:
- Mandatory on-site solar. Where the previous code only required the electrical provision for future solar, NCC 2025 requires actual photovoltaic generation for new commercial buildings, sized against the available roof area. Solar has moved from optional to expected.
- Tighter building fabric. Walls, glazing and roofs must perform better, with improved insulation and glazing requirements across most commercial classes, reducing the energy the building needs in the first place.
- A penalty on gas. The code’s emissions framework effectively penalises gas use by requiring additional renewable generation to offset it, tilting the economics firmly towards electric systems for heating and hot water.
- Higher-efficiency services. Heating, cooling and ventilation equipment must meet improved efficiency requirements, and lighting must be controlled by demand-operated devices rather than simple manual switches.
- Battery and electrical readiness. Provisions point towards infrastructure that anticipates battery storage and a more electrified building.
The cumulative effect is a code that assumes a commercial building should generate some of its own power, waste less of what it uses, and move away from fossil gas.
Why this points to all-electric
The gas penalty is the quiet driver of a larger shift. Because using gas requires a building to install additional solar capacity to offset the associated emissions, the all-electric path frequently becomes the lower-cost route to compliance as well as the lower-emission one. Heat-pump hot water and electric heating sidestep the offset penalty entirely. For most commercial projects, designing all-electric from the outset is now the path of least resistance — and it positions the asset for a grid that continues to decarbonise, rather than tying it to a fuel facing rising cost and regulatory pressure.
There is a coordination consequence worth flagging early: mandatory rooftop solar competes with mechanical plant for roof space. Cooling towers, exhaust risers and fresh-air intakes now share the roof with a photovoltaic array that the code wants spread across the available area. That is a design conversation to have at concept stage, not after the roof plan is fixed — and it is precisely the kind of buildability issue that benefits from a builder’s input during design.
Sustainability as a commercial asset, not a cost
The reframing that serves an asset owner best with 2026 NCC commercial fit-outs is to stop seeing these requirements as a compliance tax and start seeing them as value drivers. A building that generates its own power and runs efficiently has lower operating costs, which flows directly to net income and, through it, to asset value. Efficient, all-electric, well-credentialled commercial space is increasingly what quality tenants seek and what funders prefer. And a building designed to the current code is protected against the obsolescence that overtakes assets built to a standard the market has moved past.
Minimising lifecycle cost — not just construction cost — is the lens that makes sense of the new requirements. A slightly higher capital cost that delivers materially lower running costs over a fifteen or twenty-year hold is, for most owners, straightforwardly a good investment. The discipline is in designing for that outcome deliberately, which is part of how we approach commercial construction.
Getting it right from the start
The practical lesson of 2026 NCC commercial fit-outs is that energy performance can no longer be resolved at the end of design. Solar coverage, fabric performance, the choice between gas and electric, and the coordination of plant and panels on the roof are all decisions that shape the building’s form and cost from concept onwards. Bringing construction and compliance expertise in early — to plan against the current code rather than retrofit to it — is what turns the new standards from a source of cost overruns into a source of durable value.

Frequently asked questions
When did NCC 2025 take effect in Victoria?
Victoria adopted the National Construction Code 2025 from 1 May 2026. Projects that had not commenced design work before that date are generally required to comply with the new code, while projects already underway may continue under the standards in place when they commenced.
What are the main NCC 2025 changes for commercial buildings?
The major changes include mandatory on-site solar generation for new commercial buildings, tighter building fabric and glazing requirements, an emissions framework that penalises gas use, higher-efficiency heating, cooling and ventilation, demand-based lighting controls, and provisions pointing towards battery and electrical readiness.
Why does NCC 2025 favour all-electric commercial buildings?
The code requires additional solar generation to offset gas-related emissions, which often makes the all-electric path the lower-cost route to compliance as well as the lower-emission one. Heat-pump hot water and electric heating avoid the offset penalty entirely, and position the building for a decarbonising electricity grid.
Is meeting NCC 2025 just an added cost?
It can be treated that way, but it is better understood as a value driver. A building that generates power and runs efficiently has lower operating costs, which supports net income and asset value, appeals to quality tenants and funders, and is protected against the obsolescence that overtakes buildings built to outdated standards.
