Commercial energy compliance & ESD consulting.

For commercial, the ideal time to consider energy efficiency is at design. We tell you whether Section J or J1V3 is the more flexible or cost-effective path, and integrate the recommendations, without compromising the design.

commercial energy efficiency
Section J & J1V3

From single-tenant fit-outs to A-grade commercial towers.

EcoForm has years of experience helping commercial developments across Australia comply with energy efficiency, sustainability and bushfire requirements quickly and easily. Offices, warehouses, multi-storey mixed use, change of use, apartment buildings: our commercial energy consultants have you covered.

We identify the right energy assessment early, then integrate it through the documentation so it lands exactly when your certifier needs it.

01 Capabilities

Full spectrum commercial sustainability services.

01 · Section J

Section J compliance modelling

Deemed-to-Satisfy energy assessments with detailed glazing, fabric and services calculations, producing clean, defensible documentation for certifier sign-off.

02 · J1V3

J1V3 Performance

Where Deemed-to-Satisfy does not suit the design, we model performance pathways using dynamic thermal simulation, preserving design intent while meeting NCC energy targets.

03 · Green Star

Green Star strategy & submission

Section J / J1V3 across whole developments coordinated with the residential assessor for shared-wall and core compliance.

04 · ESD strategy

ESD reports for DA & planning

Sustainable Development Assessments prepared to satisfy state and council planning conditions, including BASIX (NSW) and SDA (VIC), covering energy, water, thermal comfort, stormwater and waste from concept design through to development application.

05 · LCA

Life Cycle Analysis

Whole-of-life carbon, water and material accounting. The right tool when the brief includes embodied performance or net-zero targets.

06 · Daylight & thermal

Daylight, thermal & comfort modelling

Targeted simulation for daylight autonomy, thermal comfort and overheating risk, particularly for residential apartments and education buildings.

02 Engaged early

The ideal time to plan energy efficiency is at design.

At design stage, we can adjust building features to incorporate cost-effective measures that increase energy efficiency. Trying to retrofit energy efficiency at the end of the design stage or, worse, after the building is up, is far more costly and nowhere near as effective.

Commercial buildings are a large consumer of electricity and producer of greenhouse gas emissions. With electricity costs rising and the spotlight on sustainability getting sharper every year, buildings that have considered sustainability and energy efficiency are increasingly attractive to both tenants and buyers.

With EcoForm as part of your design team, you have the information you need to make the decisions that drive long-term building performance at the point in the project where they cost the least to act on.

03 The business case

A Green Star rating moves more than carbon.

Green Star is just one of the assessments we offer, but the numbers below frame why so many of our developer clients now ask for the rating, not just the compliance certificate.

04 Project types

Wherever commercial meets energy compliance.

We have years of experience helping developments comply with energy efficiency, sustainability and bushfire requirements. The right assessment depends on the building's class, the planning authority, and the brief.

Type 01

Offices & workplaces

From single-tenant fit-outs through to A-grade towers. Section J or J1V3 for compliance, Green Star or NABERS for differentiation.

Type 02

Warehouses & logistics

Industrial fabric, large-volume conditioned spaces and PV-ready roofs.

Type 03

Multi-storey mixed use

Buildings combining retail, commercial and residential floors, with coordinated assessments across the Classes so nothing falls between them.

Type 04

Apartments & multi-residential

Small townhouse developments, medium apartment complexes, or large multi-storey, we have the expertise to assess plans and guide approvals.

Type 05

Change of use

Reclassifying a building's use triggers fresh energy compliance obligations. We work out the most achievable pathway given what's already there.

Type 06

Tourism developments

Hotels, chalets, function centres. Where high electricity loads directly impacts the operator's bottom line.

05 Two pathways

Section J or J1V3? The more flexible, cost-effective option.

The NCC gives two pathways to demonstrate commercial energy compliance. We advise which one suits your project and integrate the recommendations without compromising the design.

Pathway 01 · Deemed-to-Satisfy

Section J Assessment

The prescriptive path. The building demonstrates compliance by meeting fixed values for fabric, glazing, services and lighting: a recipe to follow.

Faster to document, easier for the certifier, and the right choice when the design already lands inside the Deemed-to-Satisfy envelope.

Best when
  • The design already aligns with prescriptive values
  • Speed and documentation simplicity matter
  • The brief doesn't need design flexibility on glazing or fabric
  • Smaller or simpler building forms
Pathway 02 · Performance

J1V3 Assessment

The modelling path. We build a dynamic thermal model of the proposed building and a reference building, then demonstrate the proposed design performs no worse.

More flexible: it preserves design intent on glazing ratios, fabric and HVAC where Deemed-to-Satisfy would lock you out.

Best when
  • Glazing area or facade design is outside DtS values
  • Architectural intent requires materials DtS doesn't cover
  • Mixed-use or complex zoning makes prescriptive compliance impractical
  • You want the option to trade fabric performance against services
06 Beyond compliance

When the brief aims past minimum standards.

Projects aim beyond minimum standards for many reasons: a client requesting a more sustainable building, a council planning condition, approval for greater lot yield, or exceeding the height restriction of an area. Whatever the reason, we have the tools to quantify it.

ESD
ESD Reports

Council-specific ESD reports fit to the authority and written to approve.

LCA
Life Cycle Analysis

Whole-of-life carbon, water and material accounting. The right tool when the brief includes embodied performance or net-zero targets.

Star
Green Star ratings

GBCA Design and As Built credit strategy, energy modelling and submission management coordinated across the consultant team end to end.

Strategy
Net-zero & carbon-neutral pathways

Strategy work for clients wanting a net-zero facility, carbon-neutral operation, or simply a defensible sustainability story for marketing.

For your role

An in-house energy consultant, by the project.

EcoForm has the personnel and technical capabilities to act as if we were an in-house energy consultant on your design team. Engage us project by project, or as an ongoing partner across your development pipeline.

We help your team make informed choices about energy, sustainability and bushfire compliance so there are no surprises at the end. That means in-office training sessions, informal conversations about potential projects, and full feasibility and consultancy services across the development life.
