Google earth satellite picture of a roof in Baghdad, Iraq, coated with 20 mils/0.5mm of TC Ceramic white. The roof is a concrete roof. Before the roof was coated with TC Ceramic, the air conditioning electrical panel was measured for two hours, from 1300 to 1500 hours.
Two days after the roof was coated with TC Ceramic white, the air conditioning system electrical panel was again between 1300 and 1500 hours. The difference was a reduction of 63% of electricity used to power the air conditioning system.
In 2004, all power for this building was provided by a large generator which was fueled by a separate fuel tank. Before the roof being coated with TC Ceramic, the fuel tank would last two days. After coating the roof with TC Ceramic, the fuel tank lasted three days. A 50% reduction in fuel consumption.
