Most people do not know of the various Australian Building codes. But in order to build an energy-efficient house, you must be familiar with the building codes. One of these is section J Compliance. 

What is Section J Compliance?

Section J compliance is an area of building codes that specifically deals with the energy efficiency of class 2-9 structures. The purpose of the assessment is to establish whether or not a building plan meets the Deemed to Satisfy provisions. Section J Report is integral in attaining an energy-efficient building. It also describes the amount of performance delivered by designing, materials, constructional methods, and components. 

Section J assessment often indicates the materials that are used in the building, as well as points out any additional requirements needed to meet the minimum required standards.

Who conducts Section J Assessment?

There are assessors who offer Section J Compliance reports. They must have qualifications in architecture, engineering, and building designs. Also, they must be certified to be able to examine a building’s thermal performance. Finally, they must be experienced in the building and construction field.

Assessors preparing the Section J Assessment reports are not legally liable for the work done by the local builders. Thus, they are considered experts in such situations since they examine all of a building’s constructional aspects.

What is included in Section J report?

DTS provisions contribute to the major part of the National Construction Codes (NCC). Builders and designers must need certain specific performance requirements. Below are the requirements:

• Building Fabric 

• Glazing

• Building 

• Air conditioning and Ventilation systems

• Artificial lighting and power

• Access for maintenance and Monitoring Facilities

Since Australia’s climate is so varied, it means different parts of the country have different heating and cooling needs. This means that energy efficiency Deemed to Satisfy provisions vary based on locations. The National Construction Codes NCC has categorized the locations into 8 zones.

 What’s the overall objection of a Section J report?

The overall reason for a Section J reports is reducing greenhouse gas emissions. The NCC aims to lessen energy consumption for cooking, heating, ventilation, and lighting among other services. It thus works towards improving systems that consume energy directly. Lastly, another role of Section J report is to maintain a bigger control level regarding how heat flows in and outside the building fabrics.

When do you need a section J report?

Anyone building a commercial building that falls between classes 2-9 requires a Section J Report. This is a requirement for all states in Australia. Most certifiers and councils need a section j assessment done during the stage of Application Development.


A Section J report typically doesn’t expire. However, if new NCC requirements are brought into effect, then you must make an effort to get an updated report. If you are putting up a non-residential building, it’s in your best interests to identify an experienced assessor to do the report for you. It will save you thousands of dollars as you will know exactly what adjustments you need to make prior to starting a construction project.
