Comparing summer night time temperatures: Cooling rain gardens vs. heating pavement

Brad Lancaster shows us dramatic pre-sunrise temperature differences of paved and unpaved areas in the urban environment, so you can see what heats us up, and what cools us down (and by how much), on summer nights. So, you can make informed choices on how to transform your home, neighborhood, and street for more a more comfortable, joyous, and productive life for all.

Filmed August 2023

I use a Fluke 62 MAX+ Handheld Infrared Laser Thermometer to take the temperature readings.
