Zurich’s North American headquarters in Chicago, USA was designed to reflect the company’s fundamental values: strength and stability. The modern structure is made up of three stacked glass prisms. The underbelly of the largest prism, which sits on top of the other two, is covered with the distinctive NATURCLAD-W panels.
The building’s sustainable initiatives mean that it has been certified LEED Platinum; the highest level of green certification possible. To achieve this certification the headquarters had to meet various environmental criteria, many of which were met in the project’s energy efficient design.
The facades increase the amount of natural light entering the building while regulating the inside temperature. Double walls help to mitigate the difference in temperature between the interior and exterior. Both of these innovative design features led to a significant decrease in energy consumption.
苏黎世保险北美总部位于美国芝加哥，其设计旨在体现公司的核心价值观：力量与稳定。这座现代结构由三个叠放的玻璃棱柱体构成。置于顶部、体量最大的棱柱体底面覆盖着标志性的 NATURCLAD-W 面板。
建筑的可持续举措使其获得 LEED 铂金认证——绿色认证的最高等级。为获此认证，总部须满足多项环境标准，其中许多都通过项目的高能效设计达成。
幕墙增加了进入建筑的自然光并调节室内温度，双层墙体则缓解室内外的温差。这两项创新设计共同带来了能耗的显著下降。
