Shopping Mall Window Glass Coating
Outdoor Climate in Dubai
In Dubai, malls like The Dubai Mall or Mall of the Emirates are gigantic spaces, surrounded by glass facades, skylights, and atrium. Because the outside climate can hit 45–50 °C with extreme humidity, maintaining a cool 20–22 °C inside requires massive energy consumption.
Summary Table
| Location | Outdoor Temperature | Heat Index Outdoors | Indoor Mall Climate |
|---|---|---|---|
|
Dubai (Summer) |
40–45 °C (peaking at ~51 °C) |
Up to 60 °C or more |
~20–22 °C (cool & comfortable) |
|
Dubai (Winter) |
24–26 °C (mild, pleasant) |
Not extreme |
Slightly cooler due to AC |
Energy Use is So High
Extreme Outdoor Heat → Cooling from 45 °C+ down to 22 °C means HVAC systems run constantly.
Glass Structures → Beautiful design but glass allows solar radiation in. Without coatings, it would overheat interiors quickly.
Foot Traffic → Thousands of visitors generate body heat and require constant air circulation.
Estimated Cooling Electricity Use
Here’s a solid, order-of-magnitude estimate for a mall like Dubai Mall (peak-summer day): ≈ 310–620 MWh per day (electricity) just for cooling.
- Cooled floor area: Dubai Mall’s internal floor area is ~550,000 m² (5.9M ft²).
- Peak cooling density for shops/malls: Typical design 150–300 W/m². (Rule-of-thumb range used by HVAC designers.)
- This implies a peak cooling capacity of ~82–165 MW (≈ 23,500–46,900 TR).
- District cooling efficiency: Dubai’s regulator study shows ~0.92 kW per RT for district cooling (i.e., ~0.262 kW electrical per 1 kW of cooling, COP ≈ 3.8).
- Daily profile: Malls don’t run peak 24/7. I assumed a realistic average 60% load over 24h (high during open hours, lower at night).
- Electrical power = Cooling kW × 0.262 → ~21.6–43.2 MW average electric draw.
- Daily energy = Power × 24h × 0.60 ≈ 310–620 MWh/day.
