This sort of thing is why I sort of hate energy star everything. Take dishwashers, for example. You can regulate the energy and water usage all you want, but it long ago got to the point where dishwashers that meet regulations basically fail to clean the dishes. Which is fine, it just causes the consumer to wash the dishes by hand either instead of or in addition to using the dishwasher. So now the dishwasher uses less energy/water, but the whole process uses net more water and takes more time.
