参考解析：

推理判断题。根据第五段第二句“Building designs...use renewable building materials such as bamboo and straw”可知绿色建筑主要使用可再生的建筑材料，如竹子和稻草。A项正确；根据第六段第一句“Careful site selection is important to minimize human impact on the surrounding environment”可知，正确的选址可减少人类活动对环境的影响，因此不能随意选址，B项错误；根据第五段最后一句“it is important to build small”可知，作者建议建小一点，节省材料，且未提及风景视野，C项错误；根据第四段第二句“Green buildings can also result in lower operating costs”可知，绿色建筑更省成本，D项错误。故选A。
