Just to remind people, the NCC (national construction code) in Australia is about to change for all new homes that will require 7 Star energy assessments in the coming months. This means that all new homes will need a higher level of thermal performance to comply with council approval.
What this means, is that the cost of new homes will be increasing due to the requirements needed to meet this new 'green' target for all new construction. Inadvertently, the costs of building a home could vary in pricing of up to $30k or more depending on design.
Careful and clever design practice by Builders, Building Designers and Architects is required more than ever to minimize these costs in conjunction with local council and estate encumbrance regulations.
Some states already have implemented this plan already. But it will soon be Australia wide and builders will then be forced to pass on any additional costs incurred to the owner to meet the minimum requirements on top of an already expensive and life changing purchase.

What are recent changes in the NCC 7-star program?
The NCC (National Construction Code) 7-star changes refer to an increase in minimum energy efficiency building standards for new homes from 6 to 7 stars under the National Construction Code 2022. This change aims to make homes more comfortable to live in, cost less to heat and cool, and help reduce greenhouse gas emissions. The new energy efficiency provisions for NCC 2022 allow for flexibility across design, materials, and orientation.
Key points regarding the NCC 7-star changes:
The increase to minimum standards for new homes will be introduced from 1 October 2023 in most states and territories.
The new energy efficiency provisions for NCC 2022 allow for flexibility across design, materials, and orientation and do not place any specific restrictions on window size.
The style of window, type of glazing, window coverings, and external shading are ways that windows can be made to be more energy efficient without compromising on size.
There will be a transition period before the mandatory introduction of the new minimum 7-star standard for new homes. The changes will not be compulsory for homes that have a building permit issued before 1 May 2024.
The new minimum requirement for new homes is a rating of 7, which means a higher level of thermal performance. Thermal performance is essentially how well your building uses and stores energy for heating and cooling.
The new energy efficiency and condensation mitigation requirements will commence in Victoria on 1 May 2024. The changes will make homes cheaper to run, more comfortable to live in, and more resilient to extreme weather.
These changes are expected to result in more comfortable and energy-efficient homes, contributing to a reduction in greenhouse gas emissions and promoting sustainable living.
