RP3009e1: Net Zero Energy Housing: Design Review Report

This report explores cost-efficient approaches for the participating volumes builders to transition ‘business-as-usual’ house design to a ‘net zero energy’ house design.  

The methodology involved firstly a workshop, where the concepts of net zero energy housing (NZEH) design were discussed amongst stakeholders and different design and technology scenarios were brainstormed. The second step was to model the chosen scenarios with the use of the CSIRO AusZEH Design Tool, and cost these to identify the most cost-effective solutions. Finally, an adequate PV system was sized to cover the annual energy needs of a typical Australian household in order to achieve NZEH.
