Renewables in buildingsProject Mirvac Net Zero Energy Homes
This report provides insights into the key challenges and lessons learnt by the Mirvac Team during construction to deliver 7-star Net Zero Energy Homes.
Mirvac released Stage 1 (no. 49 lots) to the market in October 2019 and construction of the homes commenced in June 2021. Final settlements of the homes were completed in January 2023. The construction programme was heavily affected by the industry wide impacts of the COVID-19 pandemic including restricted numbers on site and labour shortages, procurement of materials, and cost escalation. Delivering 7-star NatHERS rated, Net Zero Energy homes at a masterplanned community scale is an emerging concept and resulted in additional design and construction costs to the project. However, through the ARENA trial and a detailed lessons learnt process, Mirvac has identified design and constructability efficiencies to reduce delivery costs and impact to programme for future stages of the project.
This report will provide industry stakeholders with some of the key technical, regulatory and financial challenges and lessons learnt during construction to deliver 7-star Net Zero Energy Homes.
