Section J is a part of the building code of Australia that deals with making energy-efficient class 2- class 9 buildings. Section J assessment signifies that the building solution must satisfy the proposed provisions and legislations defined in the Section J report. Building Code Of Australia makes it mandatory that all the construction methods, building materials, design factors and the construction methods must comply by the minimum energy efficiency standards.
Section J assessment assesses the materials already used in the construction and showcase whether any additional requirements are needed to gain the minimum standard as needed in section J1. Section J2 refers to glazing calculator that helps in showing the level of performance required for the glazing to meet the minimum standard. Section J3 indicates the addons required for the envelope perimeter. Section J5 to J8 has no connection with the project but prescribes the minimum standards that need to be followed.
Section J As Part Of National Construction Code (NCC)
In many jurisdictions, a report containing compliance with section J must be issued before a construction certificate is issued. According to the National Construction Code (NCC), class 2 to class 9 buildings including all the retail apartments, industrial buildings, commercial buildings must be well-evaluated with NCC Section J Compliance Report. The report contains all the legislation that is required for the development to comply the requirements already explained in Section J.
You will need a Section J report when applying for Construction Certificate Application. Section J report shows that you have complied with the energy efficiency requirements that have been set by NCC.
Certified Energy makes the Section J reports using Deemed-to-satisfy (DtS) and verified with the aid of reference building (JV3) verification methodologies.
Deemed to Satisfy (DtS)
House architects or builders can adopt the DtS provisions if they do not want to achieve a new way of achieving performance requirements. Performance requirements refer to the performance level that must be met while carrying out the construction procedure.
According to Section J report:
- J1: Building Fabric: Walls and floors construction, roof and ceiling construction, roof lights.
- J2: Glazing: involves shading.
- J3: Building Sealing: Walls and floors, chimneys and flues, exhaust fans, roof construction, roof lights.
- J5: Air-conditioning And Ventilation Systems: Heating and cooling systems, ductwork, mechanical ventilation and time switches.
- J6: Artificial Lighting And Power: Boiling as well as chilled water storage units, interior artificial lighting, decorative lighting and power control.
- J7: Water supply to spa pool plant and swimming pool.
- J8: Access to monitoring facilities and maintenance.
Verification method refers to the test, inspection and necessary calculation to assess whether performance solution meets the relevant performance requirements or not. To verify whether your new home is energy efficient or not, consult professionals now. In Australia, you can find several specialists offering energy efficiency solutions, seek the service of the one you feel convenient.
