In Maricopa County, and many other jurisdictions across the United States, a significant portion of heat-related deaths occur because of indoor exposure. Yet there are no explicit public programs or systems designed to detect extreme heat indoors and trigger appropriate and timely response actions. This project seeks to develop, build and test a real time, targeted, knowledge-sharing platform that would issue alerts when dangerously hot conditions are measured inside one’s home. These alerts would trigger wellness checks by neighbors, family members, or other support personnel, and ultimately help connect vulnerable residents to a larger network of resources and assistance. The goal of the project is to interrupt the causal pathway from unexpected or unknown dangerous heat to severe heat-related illness and/or heat- related death with technology-triggered interventions.
