GCC Cooling Degree Days Tool
Look up cooling degree days for GCC cities to right-size cooling and forecast load.
Estimate only, based on typical annual averages at base 18°C. A puniq audit ties cooling load to your actual meters, occupancy, and tariff.
About this tool
In the GCC, cooling drives 60 to 70% of a building's energy load, so any honest energy plan starts with the climate. This tool gives you the annual cooling degree days (CDD) for the major Gulf cities at a base of 18°C, a simple measure of how hard your chillers and air handlers have to work across a full year.
Pick a city and you get its annual CDD plus a relative cooling-load index: how that city compares to the average of all six. A city above 100% runs a heavier cooling burden than the Gulf norm, so equipment is sized harder and the savings from smart controls are larger.
How to read the result
Higher CDD means more hours where outdoor heat pushes the building above its setpoint, so more cooling energy. Use the index to benchmark sites across your portfolio and to sanity-check where optimization will pay back fastest. These are typical annual averages, not a substitute for hourly weather data tied to your meters.
Frequently asked
What are cooling degree days?
Cooling degree days sum how far and how long outdoor temperature stays above a base (here 18°C) over a year. The higher the number, the more cooling a building needs.
Why base 18°C?
18°C is a common balance point: above it, buildings generally need active cooling rather than just ventilation. It lets you compare cities on a consistent basis.
How do I use the cooling-load index?
It shows each city against the 6-city average. Above 100% means a heavier cooling burden, which usually means larger equipment and bigger savings from optimized controls.
Can I use these figures for design sizing?
Treat them as planning benchmarks only. Formal sizing needs hourly weather files and a load model. A puniq audit ties cooling demand to your actual building and meters.
