Thermal Infrared Images
Infrared thermal Captures and data recording are still in progress as of 8/26/23. It is still unclear how much of a cooling difference the solar reflective coating makes. More of the image comparisons will become uploaded when data collecting period has ended.

Cool-Coat Comparison
How did you Compare the Cool-Coat?
I used the Flir Ignite Thermal Comparison tool and made a polygon selection around the before and after cool-coat images displaying the sustainable city. I then used the delta tool to compare the two average temperatures of the polygon selections. The video on the right shows the tool measuring the temperature average of the pre-cool-coat capture on the right and the post-cool-coat capture on the left.
Slide to see Before and After Comparison
The mural’s 1st coat surface layer used regular mural paint. After painting the final colors, I went over the “sustainable city” section of the mural with a clear cool-coat sealant. I documented the before and after comparison with my thermal infrared camera to see how much of a temperature-cooling difference the coat made. Two coats are on the sustainable/blue figure, and one coat is on the surrounding environment of the sustainable city. No coats are on the urban heat island/red figure and their environment.
