In Abu Dhabi, where temperatures peak at well over 100°F (38°C), keeping buildings cool is a challenge. Al Bahar Towers feature a facade with intricately designed shades that open and close in response to the sun, reducing heat gain by more than 50%. Using less air-conditioning helps reduce the towers’ carbon emissions by an estimated 1,750 tons per year.
