:274 Cool Pavement

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet environment.

1:5:10:274 EcoTip: Cool pavement is more reflective so it doesn’t build up as much heat as asphalt. This has the advantage of increasing the amount of light available because it is reflected off of the ground. When light is absorbed by asphalt or other dark surface materials the wavelength changes to heat energy that can contribute to the heat island effect in cities and higher cooling costs for individual buildings. The temperature of asphalt can be as much as 70 degrees F (40 degrees C) hotter than light colored paving.
