Cooling in Riyadh: where half your bill goes

In Riyadh's climate, cooling is not a line on the bill — it is very nearly the bill. And most of the waste is not in the temperature chosen, but in rooms cooled with nobody in them.

Three steps, in order

• Zone the house: sleeping wings during the day do not need what the living room needs.
• Tie cooling to presence: a simple sensor stops the unit after a period of vacancy.
• Use blinds before the compressor: shading a south window is cheaper than one more degree.

What we do not promise

We will not quote a specific saving figure — it depends on insulation, glazing area and living habits, and generalising it would be dishonest. What we do promise is a clear reading per circuit, so you can see where the consumption actually goes.
