“装”出来的房子,让你住得更美

2017-08-16 08:40:53   中国青年网

据了解,南京市建委、发改、规划、国土、房产等部门去年已形成相关协调联动机制,明确所有出让地块出让前均要征求市(区)产业办对装配式建筑的意见。去年6月至今,该市已有97幅出让地块明确了装配式建筑相关指标要求,总建筑面积约1345万平方米。另据统计,截至今年上半年,南京采用装配式项目43个,总建筑面积约475万平方米,其中已竣工项目5个,总建筑面积23万平方米;在建装配式建筑项目38个,总建筑面积452万平方米。这些装配式建筑中,既有政府投资的保障房、学校,也有开发企业投资的商业、住宅和美丽乡村项目。

“现在提工业4.0,以此对照,我们的建筑业目前只不过才工业1.5的水平,行业发展粗放。”省建筑产业现代化推进领导小组办公室调研员韩建忠直言,建筑产业的转型升级也至关重要。“十三五”期间,江苏的劳动力、土地、能源资源、资本价格和环境违约成本将持续攀升,传统住宅建造方式将难以为继,必须转换为以工厂化、标准化、装配化、成品化、专业化、低碳化为主要手段的现代住宅生产方式。

我省从2014年开始多次出台政策鼓励发展装配式建筑。最近发布的《江苏省“十三五”住宅产业现代化发展规划》提出,到2020年全省装配式住宅占新建住宅比例达到30%以上,并鼓励保障性安居工程建设装配式成品住房。

不会带来房价上涨

装配式建筑是否会增加建安成本、拉高房价?

先后就职于日本藤田公司和南京万科的建筑产业现代资深专家王生明表示,与传统建筑相比,装配式建筑的建造成本确实有所上升,但伴随技术的不断进步和建筑单体预制装备率的不断提升,装配式建筑的成本也在不断下降,就万科上坊保障房项目看,目前增加的成本约300元/平方米左右。

“现在全省有48个装配式建筑示范项目,现阶段成本平均上升5%-10%,主要缘于规模化程度不够、设计标准化程度和产业部门熟练度不高等。现在一些项目已通过统一设计、加强规模化等让成本有明显下降,比如南京丁家庄二期保障房项目,9万多平方米的建筑面积统一设计,统一装配装修,每平方米成本增加仅70元,装修成本不足800元/平方米。”韩建忠说。

韩建忠同时提醒,也应注意到装配式建筑带来的间接成本的下降:比如建设工期的缩短就减少了财务成本;规避了传统建筑产生大量建筑垃圾、填埋成本高的问题;之前老百姓装修时往往会敲掉一些不需要的建筑材料,大约花费123元/平方米,装配式建筑则不需要;此外,装配式建筑节水、节电,建造时可减少1倍以上的扬尘等等,“一旦规模化运用,比如预制装配面积超过20万平方米之后,就不会增加建安成本了。”

徐宏芳则表示,南京目前加大政策鼓励力度,只要采用装配式建筑达到相关指标要求的项目,就给予总建筑面积2%的奖励,且奖励部分免收土地出让金;对使用预制外墙的,另外对不超过总建筑面积2%的部分可不计入容积率,两条奖励政策可同时享受。“经过测算,这样的奖励完全可以抵扣实施装配式建筑带来的成本增加。所以,推广装配式建筑不会带来房价上涨。”
