KB Home continues to champion the important role EPA's WaterSense program plays in helping to lower its buyers' monthly utility costs and minimize their carbon footprint and energy usage. To date, KB Home has built over 19,000 WaterSense labeled and Water Smart homes — more than any other homebuilder — and installed over one million WaterSense labeled fixtures. The company estimates that its homes conserve approximately 1.7 billion gallons of water annually. More recently, the homebuilder announced that every KB home built in its future Arizona, California and Nevada communities will be WaterSense ® labeled, further helping homeowners in some of the most drought-stricken areas of the country.
