: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.

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

1:5:10:061 Tip: LED (light emitting diode) lights use much less energy and last longer than compact fluorescents. They have the additonal advantage of not containing mercury. Unfortunately for now the light is not yet very pleasant. This is a technology that should be watched closely. If they can improve the light qualities, this may turn out to be far superior to compact fluorescents.

Additional Information

Because they last so long before needing replacement, LED lighting may be the thing to use for difficult to replace lights.

The low heat output advantage of LED lighting has turned into a disadvantage for some. Some communities switched their stop lights to LEDs and found that in winter they stopped working at cold temperatures. In addition there wasn’t enough heat to keep the signals from icing up.
