Section J Report - Section J NCC 2019
What is a Section J Report, what are the Section J Requirements and what does a Section J Report cost?
What Is A Section J Report?
A Section J Report (Part J) is used to demonstrate compliance with the energy efficiency provisions contained in Volume 1 of the National Construction Code (NCC). All commercial buildings must meet the minimum standards detailed in the NCC (previously known as BCA).
The regulations in the NCC apply to new commercial buildings, renovations, alterations and extensions. This includes apartments, board-houses, caretaker’s residence’s offices, cafes, shops, restaurants, laboratories, schools, medical centres and more.
The most appropriate way to show compliance for most projects is to use the Deemed to Satisfy provisions contained in Section J of the NCC. A Section J Report will show how your proposed building complies with the Energy Efficiency Requirements of the Building Code of Australia.
When Is A Section J Report Required?
A Section J Report is required when applying for a construction permit for a commercial building. The following types of buildings are required to comply with the Section J NCC requirements:
- Class 2: Apartment buildings
- Class 3: Residential buildings such as a boarding-house, guest house, hostel, lodging-house or backpackers accommodation
- Class 4: A single dwelling in a building that is Class 5, 6, 7, 8 or 9. An example of a Class 4 part of a building would be a caretaker’s residence in a storage facility.
- Class 5: An office building used for professional or commercial purposes, excluding Class 6, 7, 8, or buildings
- Class 6: A shop or other building that has the purpose of serving goods or services directly to the public. Examples include a cafe, restaurant, bar, shop, kiosk, hairdresser’s, showrooms or service stations
- Class 7: Carparks, storage facilities or wholesale display buildings
- Class 8: Laboratories, or buildings for the purpose of producing, assembling, altering, reparing, packing, finishing or cleaining goods. An example would be a factory
- Class 9: Buildings of a public nature. This includes health-care, an assembly building within a school and aged care buildings
If you are planning to build a new commercial building or planning an extension or renovation you will require a Section J assessment to demonstrate compliance with the energy efficiency provisions. The NCC applies Australia wide and all councils will require compliance.
What the Section J Requirements?
Section J of the NCC 2019 details the performance requirements that your commercial build needs to meet. You will need to meet the Total R-Values required for the floors, roofs, walls. You will also need to meet glazing requirements and air movement requirements.
The provisions also detail requirements for the testing and installation of insulation, compensation for loss of ceiling insulation from penetrations, floor edge insulation and the sealing of the building.
The requirements for Section J of the NCC 2019 includes:
- Section J Energy Efficiency
- Part J0 Energy Efficiency
- Part J1 Building Fabric
- Part J3 Building Sealing
- Part J5 Air-conditioning and ventilation systems
- Part J6 Artificial lighting and power
- Part J7 Heated water supply and swimming pool and spa pool plant
- Part J8 Facilities for energy monitoring

What Does A Section J Report Cost?
The cost of a Section J Report can vary depending on the type of building and complexity of the project. Typically most reports using the Deemed to Satisfy provisions will range from $500-$4000 (plus GST).
The following aspects of the design can impact the cost of the report:
- The number of different wall types
- The number of different roof types
- The number of storey’s
- The type of floor construction
- The amount of shading and glazing
Large projects such as hotels can have significantly higher costs because they may be more appropriate to complete using a JV3 assessment (modelling the entire building in software to calculate energy usage). We provide quotations on a case-by-case basis due to the complexity of these jobs.
