COMMERCIAL ENERGY COMPLIANCE

Section J Solutions. Smarter Building Compliance.

Section J in the National Construction Code (NCC) focuses on energy efficiency, establishing requirements for the design of energy-efficient buildings and their systems.

Its objective is to minimise peak energy consumption, reduce greenhouse gas emissions and ensure occupant comfort. Positive Eco provides Section J assessments and reports through both Deemed-to-Satisfy and J1V3 verification approaches.

OUR EXPERTISE

Smarter Energy Solutions. Better Building Outcomes.

At Positive Eco, we help architects, builders and developers navigate the energy efficiency requirements of NCC Section J.

Our approach combines practical building design knowledge with energy performance assessment to identify suitable compliance solutions for commercial building projects.

Whether your project requires a Deemed-to-Satisfy assessment or a performance-based verification approach, we work with your design team to support energy-efficient and compliant building outcomes.

01 / COMPLIANCE

Deemed-to-Satisfy Assessment

Assessing building elements and systems against the applicable NCC Section J energy efficiency provisions.

02 / PERFORMANCE

J1V3 Verification

Using energy modelling to evaluate building performance and explore alternative design solutions.

03 / ENERGY MODELLING

Building Performance Analysis

Supporting informed design decisions through building energy analysis and simulation-based assessment.

SEE HOW IT WORKS

Understanding Buildings Beyond the Blueprint.

Energy modelling helps evaluate how a building performs beyond its architectural drawings.

Through building performance analysis, design teams can explore energy efficiency measures and assess the effect of different design decisions before construction.

PERFORMANCE SOLUTIONS

J1V3 Assessment. Greater Design Flexibility.

Commercial buildings must meet applicable energy efficiency requirements under the National Construction Code (NCC).

The traditional Deemed-to-Satisfy approach specifies minimum requirements for building elements and systems. The J1V3 performance solution provides an alternative assessment method under earlier NCC provisions.

This alternative approach allows losses associated with glazing to be offset by better-performing building components, providing flexibility to trade off performance between elements of the building fabric.

J1V3 modelling uses prescribed building operating assumptions and Australian weather data to evaluate energy performance. Positive Eco uses IES building simulation software to support these assessments.

Efficient building fabric is a long-term investment, as it typically outlasts mechanical and electrical building services.

FREQUENTLY ASKED QUESTIONS

Your Questions, Answered.

Everything you need to know about Section J compliance, NABERS energy modelling and daylight simulation for commercial buildings.

What's included in a Section J report?

A Section J report assesses the applicable energy efficiency requirements under the National Construction Code (NCC).

Our assessment covers the relevant provisions of Part J4 (Building Fabric) and Part J5 (Building Sealing), helping demonstrate compliance with the applicable requirements.

How does NABERS energy modelling work?

NABERS energy modelling involves analysing the design of commercial buildings to estimate their annual energy consumption, including heating and cooling requirements.

Specialised energy simulation software is used to calculate predicted energy consumption based on building design, operational schedules and usage patterns.

For NABERS purposes, the assessment follows specific behavioural and operational assumptions prescribed for the relevant rating methodology.

The estimated energy consumption is then compared against established benchmarks to determine a predicted NABERS star rating.

What is the best software for daylight simulation in Australia?

Radiance and IES Virtual Environment (IES VE) are recognised software tools used for daylight simulation and building performance analysis.

These tools help evaluate natural daylight availability, building orientation, glazing performance and indoor daylight conditions.

The most suitable software depends on the project's design, simulation requirements and assessment objectives.
