Smart HVAC and Climate Control for Dubai's Extreme Heat
Dubai's extreme summer heat (reaching 50°C) makes HVAC your villa's largest energy consumer. Smart climate control can reduce cooling costs by 30-40% while improving comfort.
The Dubai HVAC Challenge
Climate Reality:
- Summer temps: 40-50°C (104-122°F)
