Volume builders may need to make some adjustments to their standard plans for future volume projects to meet the new requirements. However, applying improved design and orientation applied effectively, can make a significant contribution to meeting 7 stars without significant additional upfront costs. A level of customisation of volume builders’ standard plans may be required in some cases by exception, but not as standard.
Increases in materials costs are affecting the construction industry internationally and are not unique to Australia. Some of these supply issues were in place prior to COVID-19 and were further exacerbated by pandemic impacts.
Achieving a 7 star rating can be cost-effectively reached through a considered combination of design and orientation, rather than simply replacing existing designs with higher-performing or additional materials.
Further information for the industry on understanding the uplift from 6 to 7 stars, with practical tips and advice are included in Sustainability Victoria online resources.
