$GDGI According to researchers at UC Davis, the world NEEDs innovations like Cool-n-Save. HVAC operations account for more than 25% of electricity consumption in California alone. In climates where heat is more intensive (e.g, the U.S. "sunbelt region", Central America, South America), HVAC operations can account for more than 40% of annual energy consumption. The California Energy Commission California Commercial End-Use Survey (CEUS) reports that roughly 65% of commercial floor area is cooled by 'split system' packaged rooftop units. About 80% of the individually connected air conditioning systems fall in this category.
