Designing 'Chill City': An Interactive Game Supporting Public Learning about Urban Planning for Extreme Heat

Climate change and the urban heat island (UHI) effect are increasing extreme heat risk in cities across the world, and have already made extreme heat the top weather-related cause of death in the United States. Despite this, understanding of viable strategies to address extreme heat is still limited, for both decision-makers and the public. Using a design-based research methodology, we developed an interactive educational game, "Chill City," which teaches players about possible heat planning strategies and their tradeoffs. We surveyed adult, non-expert players to understand the game's reception and impacts. Players expressed that they enjoyed the game and that it helped them better understand heat planning strategies and the environmental, social, and economic tradeoffs associated with them. We argue that environmental games offer educational potential for adult learners on issues of extreme heat and climate change that should be further explored to inform effective approaches and designs.
