Rooftops on new buildings built in commercial zones in France must either be partially covered in plants or solar panels, under a law approved on Thursday. 法国议会3月19日通过新法案,规定法国商业区的新建筑物屋顶须由植物或太阳能电池板部分覆盖。 Green roofs have an isolating effect, helping reduce the amount of energy needed to heat a building in winter and cool it in summer. 绿色屋顶有隔离效果,能帮助减少建筑冬天加热或夏天制冷所需的能量。 They also retain rainwater, thus helping reduce problems with runoff, while favoring biodiversity and giving birds a place to nest in the urban jungle, ecologists say. 生态学家称,绿色屋顶还能贮存雨水,缓解地表径流。不仅如此,绿色植物还有利于维护生物多样性,为鸟类在市区内提供栖息之地。 The law approved by parliament was more limited in scope than initial calls by French environmental activists to make green roofs that cover the entire surface mandatory on all new buildings. 不过,此次通过的法案同环保人士的最初提议相比,范围有所缩小。环保人士起初要求对境内所有新建筑物进行强制性“绿色”覆盖。 The Socialist government convinced activists to limit the scope of the law to commercial buildings. 社会党政府最终说服环保人士把适用范围缩小到商业区建筑。 |
