[单项选择]It is officially known as the Swiss Re Tower, or 30 St. Mary Axe. Londoners universally refer to the new 41-story building as "the Gherkin (小黄瓜) ", though it actually looks more like a pine cone. As a typical example of green architecture, what is most remarkable about the building is its energy-efficiency. Thanks to its artful design and some fancy technology, it is expected to consume up to 50% less energy than a comparable conventional office building. Green architecture is changing the way buildings are designed, built and run.
Proponents (支持者) of green architecture argue that the approach has many benefits. In the case of a large office, for example, the combination of green design techniques and clever technology can not only reduce energy consumption and environmental impact, but also reduce running costs, create a more pleasant working environment, improve employees’ health and productivity, reduce legal liability, and boost property values and rental returns.
