Qatar University has developed air conditioned helmets for site operatives.
The helmets are solar-powered with a built-in fan that reduces the skin temperature of construction workers by up to 10 degrees centigrade.
A solar panel fixed on top of the helmet powers a fan to take in hot air, which is then cooled by phase change materials and filtered onto the worker’s head. The combined mechanism, plus a back-up battery, adds 300 grams to the weight of the hat, and $20 to its cost.
This helmet allows for safer conditions for those building stadiums for the 2022 World Cup and contributes to an overall safer working culture in this region.
