As temperatures increase across the United States, some populations are more at risk for heat-related death and illness than others. One of these at-risk demographics is mobile home and trailer park inhabitants, who are disproportionately represented among indoor heat-related deaths (Solís, “Heat, Health”). In this paper, we outline a cost-benefit analysis that was used to calculate the net present economic value of projects related to reducing heat burden on mobile home owners and parks in Maricopa County. We use this model to assess solutions developed by student teams under the Knowledge Exchange for Resilience’s Summer Heat Resilience Challenge. We find that one of the seven solutions has a positive net present value (NPV) even in the lowest effectiveness (10%), while three more solutions have a positive NPV in the mid-level (50%) effectiveness scenario, showcasing their economic viability.

In the face of profound shock and change, individuals, organizations, and communities are seeking new ways to prepare for an uncertain future, their only certainty being that the present trajectory of change will intensify. Pandemics, wildfires, heat waves, hurricanes, flooding, social unrest, economic strife, and a rapidly changing climate system comprise a resounding wake up call: we must reinvent our institutions to think about and act with a resilient mindset. The purpose of the playbook is to support these efforts and build stronger, adaptive, and resilient communities.
