Section J Assessment and Compliance Reports

In May 2006 the Australian Building Codes Board introduced a new chapter into the Building Code of Australia (BCA), titled “Section J - Energy Efficiency”. These regulations were mandated for all Class 2 to 9 buildings thereby providing energy efficiency codes for all building types. The current objective of Section J is to reduce greenhouse gas emissions through a low carbon economy.
 
As part of the Building Permit process, your Building Surveyor will normally request a BCA Section J Compliance Report from a suitably qualified person or company. Buildings and their services are required to achieve minimum energy efficiency performance standards as stipulated under each Part of Section J. Compliance with the regulations can be achieved by adopting the Deemed-to-Satisfy provision.
 
 
The Building Code of Australia  (BCA) in 2011 had a major change in documentation and title, due to alignment with the Disability Act (2006) and the Access Code in the Disability (Access to Premises – Buildings) Standards, it is now known as  The National Construction Code (NCC).
Section J objective remains the same, that is: “to reduce greenhouse gas emissions by efficiently using energy”.
Planning to achieve compliance for the NCC Section J is ideally done at concept design stage to results in a ‘Deem to Satisfy’ Report.

Deemed-To-Satisfy

The DTS approach for sole-occupancy units of a Class 2 building and a Class 4 part differs from the approach taken for other Classes of building. NCC requires a software rating.
 
For Classes 5, 6, 7, 8 & 9 buildings, each element within Section J is designed to work as part of a system. The Section J report will cover:

J1
Building Fabric
roof and ceiling construction, roof lights, walls, floors.
J2
Glazing
shading, glazing.
J3
Building Sealing
chimneys & flues, roof lights, external windows & doors, exhaust fans, construction of roof, walls, floor.
J5
Air-Conditioning & Ventilation Systems
air-conditioning, mechanical ventilation, ductwork, time switches, heating & cooling systems.
J6
Artificial Lighting & Power
interior artificial lighting & power control, decorative lighting, external lighting, boiling water & chilled water storage units.
J7
Hot Water Supply & Swimming Pool & Spa Plant.

I2
