Should your local government invest in experimental materials to lower urban heat levels?
City officials will unveil a 200-foot heat-resistant mural at Cave Creek Sweetwater Park on November 1, 2026. The project aims to test whether the specialized coating can lower surface and air temperatures in the local park.
Why it matters
Phoenix is testing this innovative material to determine if it can mitigate extreme heat levels in public outdoor spaces. The study seeks to evaluate if coatings traditionally used for industrial roofing can be adapted to improve thermal conditions for residents.
The installation features a 200-foot mural coated in EnKoat, a material typically utilized for rooftop temperature mitigation. The project is currently at the stage of material application, with performance metrics still to be assessed.
The players
EnKoat
This Phoenix-based company was founded by Arizona State University alumni and specializes in heat-mitigating materials for rooftops.
Arizona State University
This public research university is the alma mater of the founders behind the heat-resistant material used in the mural.
The details
Painted using a heat-mitigating material from the Phoenix-based company EnKoat, the mural serves as a functional research site. City officials are collaborating with local researchers to monitor the installation's impact on the surrounding environment.
Timeline

Travel Outlook
This project follows the trajectory of the City of Phoenix Heat Response Plan by testing new passive cooling technologies in public recreation spaces. It reflects an ongoing effort to mitigate extreme summer temperatures that traditionally impact the seasonal usage of local parks.
Residents visiting Cave Creek Sweetwater Park can expect to see the new mural starting November 1, 2026. While the project is experimental, it could eventually lead to new design standards for outdoor surfaces if the material successfully lowers local temperatures.
The takeaway
Innovative cooling solutions are being tested in public spaces to see if industrial materials can improve comfort for park users. Residents are encouraged to monitor the park for upcoming temperature findings as the city continues its research into heat mitigation.
