问题     What is most remarkable about the building of the Swiss Re Tower is not its name or its shape, however, but 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  【C1】  office building.
    Most people are not used to thinking of large buildings as vast, energy-guzzling machines. But that is  what they are. In America, buildings 【C2】 for 65% of electricity consumption, 36% of total energy use and30% of greenhouse-gas 【C3】 . So making buildings more energy-efficient could have a significant 【C4】on energy policy, notes Rebecca Flora of the Green Building Alliance, a group that promotes sustainable architecture. That is a key goal of the "green architecture" movement, which is changing the way buildings are 【C5】  , built and run.
    Proponents of green architecture 【C6】  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 【C7】  , create a more pleasant working environment, improve employees’ health and  【C8】 , reduce legal liability, and boost property values and rental returns.
    The term "green architecture" only came into use in the 1990s, but the movement’s roots can be  【C9】 back a long way. Crystal Palace in London and Milan’s Galleria Vittorio Emanuele II, for example, built in 1851 and 1877 respectively, used roof ventilators and underground air-cooling chambers to regulate the indoor temperature. Today’s enthusiasm for green architecture has its origins in the energy crisis of the 1970s, when architects began to question the  【C10】of building enclosed glass-and-steel boxes that required massive heating and cooling systems. word bank:
