This document summarizes a presentation on assessing energy risks to urban activity systems based on urban form. It discusses (1) using the RECATS model to analyze energy supply and conduct risk analysis for different urban development scenarios, (2) a case study of Christchurch, New Zealand that finds centralized development has the lowest energy risks while urban sprawl has the highest, and (3) conclusions that RECATS can assess future scenarios and energy disruption probabilities to inform low-risk urban planning.
