Which says, for Commercial energy use:
25% lighting
13% heating
11% cooling
6% refrigeration
6% water heating
6% ventilation
6% electronics
You could find gains in ventilation, electronics, refrigeration, cooling, and probably even heating if this technology was widely used and performs well over all uses, so the 7% isn't out of the question, even if it might be very optimistic.
