Building Standards: How to Pass the National Construction Code

New establishments built anywhere in Australia should follow the energy efficiency provisions of the National Construction Code (NCC), formerly known as the Building Code of Australia (BCA). Since the 1980s, the government has focused on the energy efficiency of buildings by reducing the use of heating and cooling energy. This way, the production of greenhouse gas emissions will decrease. Published in 2011, the NCC has three volumes: Volume 1 for Class 2 to 9 buildings (Commercial), Volume 2 for Class 1 and 10 buildings (Residential), and Volume 3 for plumbing and drainage of all buildings.

Passing the NCC

The Building Certifiers and Certifying Authorities (BCCA) will request for Energy Efficiency Performance Assessment Reports from those planning to build new establishments. These include the deemed-to-satisfy approach and energy modelling provisions, which can affect the building energy rating results of your construction project.

What is the Deemed-to-Satisfy Approach?

This is the preliminary performance assessment of your construction project, which includes two parts:

  1. Energy Rating Software – Reduce heating and cooling energy until it reaches the 6-star minimum rating. In some climate zones, however, it’s acceptable to negotiate the energy rating. The Nationwide House Energy Rating Scheme (NatHERS) should authorise the measurement software used to ensure accurate results.
  2. Elemental BCA DtS Provisions – Follow the provisions regarding the use of floor, wall, and roof materials, glazing, and air movement. To do this, you’ll need to test the installation of thermal breaks, floor edge insulations, and insulators.

What is Energy Modelling?

This uses computer-based simulations to measure energy consumption, daylight effects, and other design characteristics. It analyses the building elements before allowing you to start a project. This way, you can find alternatives in case your building proposals need changes. This can also help strategise investments, so you can improve the establishment’s energy use.

The National Construction Code (NCC) aims to save the planet from harmful emissions through accurate appliance energy ratings and building construction requirements. If you want to get permission for your construction project, it’s ideal to get the advice of experts in different fields.
