Grass: Nature´s Air Conditioning

A healthy front lawn has the same cooling effect as an 8-1/2 ton air-conditioning compressor. The plants transpire (evaporate water through the leaf surface) to cool themselves, and cool the immediate area to boot. About half of the heat energy directed to a turf area is eliminated by transpiration. When the temperature of the sidewalk is 100 degrees Fahrenheit, the temperature of the adjacent turf remains near 75. This cooling may last into the night, with studies showing a 13-degree cooling at 9 p.m. (Mississippi State University).
