By setting the minimum requirements for building fabric and services of commercial buildings in Australia, the NCC Section J report aims to help reduce greenhouse gas emissions. Most of the greenhouse gas emissions are the byproduct of energy use. Therefore, NCC Section J establishes minimum requirements for the building industry to enhance energy efficiency.
Sources of greenhouse gas emissions that are subject to the requirements of Section J are:
- Space heating
- Space cooling
- Lighting (internal & external)
- Base building appliances
- Heated water supply
- Pumps & control
- Fans & control
- Heat rejection
- Lifts
- Mechanical ventilation and exhaust
- Swimming pool/spa
In a Section J energy report, minimum requirements are outlined for the above sources.
