Byron Shire, NSW, Australia, aims to transition to zero emissions within ten years in five sectors - energy, buildings, transport, land use and waste. This study investigates the potential of Geodesign to effectively map the shire during this transition. A contextual study of the shire's residential pockets is initiated using open source Geographic Information System (GIS) data and a typical case study site selected based on demographic information. CO2 equivalents from current electricity usage and offsets from renewable energy systems are added to the database and visualized in ArcGIS software. Site specific benchmarks are derived as the first step of developing a Regenerative Sustainability Design (RSD) strategy using Geodesign tools. The tenets of RS require each building to use systems that enhance overall ecosystem health by achieving positive outcomes for energy, waste, water, biodiversity, etc. ArcGIS is a system for designing built and natural environments in an integrated process. It enables evaluation of RSD alternatives against their impacts, collaborative decision making and community engagement (via apps, online surveys). Vector data can be directly quantified, multiple parameters accounted for and the onground situation presented to stakeholders in a legible and easy to understand format. Complex datasets can be quickly accessed and visualized in order to identify opportunities for positive contributions to the community. This work shows the value of Geodesign for community planning processes to drive positive change. ArcGIS can assist in holistic assessments to identify the most effective retrofit opportunities, monitor the transition to zero emissions over time and inform policy.
