Residential housing is a major contributor of greenhouse gas emissions with most emissions being generated during the operation of buildings. Josh’s House has shown that high performance, Net Zero Emissions Homes (NZEH) are accessible to the volume market. The challenge is to now translate this into mainstream construction industry practice.

Through the collaborative delivery of NZEH display homes in new housing developments around Australia, Josh and his research colleagues are looking to establish an agreed position on cost barriers and customer perception of NZEH homes, whilst engaging industry and informing the market.

The findings of the study are being documented in a series of videos and publications.
