Carbon Zero by Off-grid Technologies

Abstract

To mitigate the effects of climate change, low-carbon developments, such as zero-carbon building systems, are unavoidable in both existing and future structures. In this regard, a comprehensive analysis of four off-grid systems (Grey water system, Green curtain, Off-grid toilet, and Double roof house) was done in the off-grid tech lab at The University of Sydney. The mentioned systems were designed, constructed, and operated for a certain period (3 - 15 months), proving their credibility and effectiveness. Out of the four systems, only Double roof house was a scaled-down model (3:1). The work

All prototypes collectively aimed to determine if off-grid systems can be operated in a way that does not compromise the quality of life. The research project embraced a biophilic approach, viewing each prototype as part of a larger system interacting with nature. Waste generation was minimized, and valuable performances were achieved with the least resource usage and minimal human interventions. The prototypes endorsed and demonstrated that sustainability and modernity can coexist without compromising on lifestyle. For instance, the Grey water system provided water to plants without any waste going out of the project boundaries, the Off-grid toilet functioned as a contemporary toilet while producing compost, the Double roof house roofing system powered appliances and ensured indoor comfort, and the Green curtain offered indoor comfort with indoor living greenery. These findings highlighted the feasibility of off-grid technologies without sacrificing modern-day conveniences.
