Big Key Changes Coming Into Effect In Section J 2019

Australian National Construction Code Section J is ready to build a more energy efficient bedrock tinkering the energy performance for commercials and residential buildings. This overhaul has been incorporated owing to the rising greenhouse gases in Australia. So if you are planning to start a new project within the next 12-18 months, then wait… Read this blog on BCA section J changes. By the time you start, these changes would have got highly relevant.

So the question that most of the builders ask why the changes?

The answer, it was necessary! Section J 2019 changes aim to mitigate the greenhouse gases emission and increase the energy efficiency of the Australian building blocks by 40% in 2030. So we can say, it is a broader strategy laid down by the Australian Government bodies after consulting rigorous discussion and research by the Australian Building Board. The changes are also incorporated for imparting more flexibility on the verification options and include NABERS energy and Green Star compliance against these sets of changes.

The next question that pops up is, what are the exact changes?

The changes are focused more on improving the two main components of architectures,

1) The commercial buildings and

2) The Residential buildings

Let’s read further to understand more about it.

1. Commercial buildings:

Section J changes 2019 needs to be strictly followed by the commercial building owners who now have the capacity to save 53% of energy. Further, this can be divided for Class 2, Class 3, and Class 5 to 9 buildings as:

• It is now necessary to increase and quantify the minimum performance requirements;

• All the basic comfort levels should be included in the buildings itself;

• The owner should work upon increasing bridging requirements;

• Instead of having separate glazing and walls concept, it focuses on the “whole facade” performance approach;

• The air conditioners and the ventilation systems should be efficient enough to increase the building efficiency;

• Photovoltaics should also be included;

• Improved current JV3 standards;

2. Residential Buildings:

The changes are made to achieve energy savings by up to 18% for residential buildings. The codes are simplified for the residential buildings of Class 1, Class 2-solo-occupancy and parts of class 4 buildings. Some other extensions of the improvements are:

• Separate heat and cooling load limits;

• New verification methods for building envelope sealing.

When are the changes coming into effect?

The changes will be effective from 1st May 2019 and it is expected to best benefit the building industry. All the building owners have to strictly adhere to the changes and participate the best in the process of improving energy efficiency in Australia.
