Looking for ways to reduce your electrical usage?
Try a concrete parking lot and sidewalk
One of the biggest users of energy are electric lights. If you are lighting a parking lot or sidewalk, using
light-colored concrete instead of black surfaces will reflect the light and reduce the number of lights you
will need. The Albedo effect is a ratio of solar radiation that is reflected off of a surface compared with the
amount that shines on that surface. Concrete is 10-14 times more reflective than newly paved asphalt.
Reducing the Heat Island Effect
Studies show that using
surfaces have 33%
less operational energy
costs than a surface paved
with asphalt. Concrete
surfaces need 24% fewer
lights and lower wattage
light bulbs to achieve the
same amount of light as
asphalt paved surfaces.

Normal Albedo ratios for concrete range from .4-.7. You may
receive LEED credits for reduction of Heat Island Effect by
using concrete with a Solar Reflective Index (SRI) of 29 or
greater. For more info,
