Their article states the benefits of Qatar Cool include the following

"Lower operation and maintenance cost over conventional systems."

The yearly running costs for a 200sqm apartment is QR16,920 (QR7,920 consumption and QR750 per month X 12 months). Per month this is QR1,410 just for cooling. Even running all my AC's in my villa at the height of summer I do not get an electricity bill for QR1,410.

If I can run my AC's and light up my large villa for less money where are the lower costs.
