  欧美建筑平均寿命是80年以上,相比之下,我国建筑平均寿命却只有30年,不及国标最低使用年限的60%。房子拆一次创造了GDP,再盖一次又创造了GDP,在这种“破坏式建设”的怪圈中,在重复建设的过程中,我国创造了两项世界第一:在消耗了全球最多的水泥和钢材的同时,也生产出全球最多的建筑垃圾——每年高达4亿吨,建筑垃圾数量已占到垃圾总量30%~40%。英国《金融时报》指出:“中国可能已经成为全球最大的建筑浪费国”。“英年早逝”的“短命建筑”与建设“节约型社会”的精神相悖,更是与科学发展观严重背离。其后果不止是造成社会资源的巨大浪费,同时产生大量的建筑垃圾,被堆放和填埋在城市周围,陷入“垃圾围城”的局面,不仅占用土地,其中含有各种有害化学物质,严重腐蚀地表和污染地下水源,危害极大,对人类生存环境构成威胁;而且割裂了城市历史文脉,削弱了城市文化传承,城市风貌遭到严重破坏。房屋拆迁引发社会矛盾,影响社会稳定。

  结合钢结构的特点,以绿色建筑为主题,按照“零资源、零能耗、零排放、零污染、零工地、零距离”这“六个零”的建筑设计理念,开发钢结构住宅建筑产品。“零”资源。最大限度以钢材和其他可再生资源作为建筑材料,利用钢材循环生产技术和钢结构技术;“零”能耗。采用新型节能保温透气的钢结构建筑配套建筑材料、被动式节能空调技术和清洁能源集成应用技术,包括水蒸发制冷、太阳能集电、集热技术,将建筑全生命周期能耗降到最低;“零”排放。钢结构降低粉尘,采用雨污水回收及渣物处理,使二氧化碳和污水污物排放被杜绝;“零”污染。利用现代钢结构技术,工业化和标准化制造,集成生产、施工现场快速拼装的经营模式,使建筑过程无噪音、无大气污染、无污水排放;“零”工地。将施工现场需要的关键构件和部件移至室内工厂生产,生产完成后到现场实行快速拼装施工工法,提高作业功效、缩短施工周期,实现“零”现场施工装配;“零”距离。以实现了构件标准化、供应系列化、生产工厂化、施工装配化,随时随地通过物联网智能控制系统操控营造和使用的耗能设备,实现零距离连接。
