绿色建材认证体系系统的政策配套
Green building certification system supporting policies
刘翼介绍，绿色建材认证将基于几个原则。第一，绿色建材性能认证对成品的关键指标，相比国家标准或是行业标准的门槛，会提出更严格的要求，向国际水平靠拢，“因为你是绿色建材，不是普通建材”。刘翼举例，水性涂料VOC含量限值120克/升，环境标志产品认证要求低于80克/升，北京奥运鸟巢要求低于50克/升，欧洲的标准要求30克/升。
Liu Yi introduces, green building certification will be based on several principles. First, the key indicators of green building materials performance certification for products, compared with the national standards or industry standards, will be made more stringent requirements, close to the international level, "because you are not ordinary green building materials, building materials". Liu Yi example, water-borne coatings VOC content limit of 120 g / L, product certification requirements of less than 80 g / L environment symbol, Beijing Olympic Bird's nest require less than 50 g / L, asked the European standard 30 g / l..
另一方面，关注绿色建材全生命周期的环境影响，这也是认证的重点。据悉，建材的国家标准或行业标准没有涉及到建材从生产到使用全生命周期的环境影响，包括资源消耗、能源消耗还有三废排放和温室气体排放，是否废弃物利用和资源综合利用等。对此，技术上已经有一套办法，通过下工厂实际审查企业的表单、产能、用电量。目前，水泥、玻璃、卫生陶瓷、铝型材等已有相关标准，对单位产品生产能源消耗进行限额，分及格值和限定值两档，“我们可能就要按限定值提出要求”。
On the other hand, pay attention to environmental effects of green building materials life cycle, which is the emphases of certification. It is reported, the national standard or industry standard building materials not related to building materials from production to environmental effects of the use of the whole life cycle, including resource consumption, energy consumption and waste emissions and greenhouse gas emissions, whether the waste recycling and resource comprehensive utilization. In this regard, there is a way to have the technology, through the actual examination of enterprise form, capacity, power consumption. At present, cement, glass, ceramics, aluminum and so on relevant standards for energy consumption per unit of product, the production quota, passing the value and limit of two files, "we may according to the limit value requirement".
由于建材涉及种类繁多，绿色建材的认证办法将可能是个通则;建材的认证标准则具体到产品的各项指标，根据建材产品分类标准，分为六到七个大类，包括结构、围护、幕墙、装饰装修等，建筑材料分混凝土结构、钢结构、木结构等。
Due to a wide variety of building materials, green building certification will likely be a general; building materials certification standard is specific to each index of the product, according to the classification standard of building materials products, divided into six to seven categories, including structure, wall, curtain wall, decoration, building materials, steel structure, concrete structure wood structure.
不可回避的是，绿色建材的生产成本将高于普通建材。刘翼的感觉是，高得多。绿色建材面市了，还得下游消费方认可，因此刘翼认为需要系统的鼓励政策，“给生产者或是消费方补贴，鼓励下游选用绿色建材在绿色建筑评价中能加分，招投标加分，建筑使用多少可以补贴等”。据悉，具体的鼓励政策还在研究中，如何补贴还需要和住建部等部门协商。
Unfortunately, green building materials production costs will be higher than the ordinary building materials. Liu Yi's feeling is, much higher. Green building materials market, but also to the downstream consumer acceptance, so Liu Yi need encouragement policy, "to the producer or consumer subsidies, encourage downstream points in the selection of green building materials green building evaluation, bidding points, building many can subsidies". It is reported, encourage research in policy is still in the concrete, how to subsidies and Housing Department consultation.
对于政府来说，推行绿色建材，相比普通的建筑材料，撇开建筑性能不说，但对于生产的消耗是个巨大的节约。以高强钢筋为例，用HRB400钢筋代替HRB335钢筋，可节省10%~14%的钢材，用HRB400钢筋代换小直径HRB235钢筋，节省40%以上的钢材。
For the government, promoting green building materials, compared with the ordinary building materials, apart from building performance did not say, but for the production of consumption is a huge savings. The high-strength steel as an example, use HRB400 instead of HRB335 reinforced bar, can save 10%~14% steel, HRB400 steel replacement of small diameter HRB235 steel, saving more than 40% steel.
