The brand selectivity of China's indoor environment and building materials is far greater than that of developed countries. At present, the indoor environment or building materials brands sold in China mainly come from developed regions in Europe and North America. 

Among them, Germany is more suitable for costumers in Europe, and the United States is mainly in North America. Due to the language, market understanding and trust in product certification, it is difficult for costumers to choose a trusted brand. Most of them rely on the introduction of salespeople in the process of brand selection. When the demand of the continuous market increases, all unexpected or dishonest phenomena occur.

中国室内环境和建筑材料的品牌选择性，远远大于发达国家，目前在中国销售的室内环境或建筑材料品牌，集中来源于欧洲、北美发达地区，其中欧洲以德国为比较符合购买者的喜欢，北美地区以美国为主。由于语言、市场了解程度和对产品认证的了解信任度，让购买者很难选择到值得信赖的品牌，多数在选择品牌的过程要依靠销售人员的介绍。在持续市场的需求量增大时，就出现了一切让人意想不到的或是不诚信的现象发生。

Gong: how do developed countries choose building materials?

宫：发达国家是如何选择建筑材料的？

IS: In fact, the sales of building materials brands in developed countries around the world are completely different from that in China. First of all, building materials in Europe and North America are basically sold in shop similar to Chinese supermarkets. Well-known building materials supermarkets in Europe, such as OBI in Germany, Leroy Merlin, Adeo and B&Q, and Homedepot, Lowes such a large building materials market to complete sale, they have a strict pre procurement quality evaluation system and strong after-sales ability. Second, the sales of building materials in Europe and the United States do not depend on the brand to create popularity in business. It mainly depends on the perfect third-party market certification system. Certification is also a way to ensure the quality and reputation of products. Therefore, in developed countries, as long as there is certification and sold in the large building materials market, they can be selected on demand, and the brand difference is small.

IS：建筑材料品牌其实在全球发达国家的销售和中国是完全不同的，首先呢，欧洲和北美的建筑材料基本在类似于中国超市一样的商业进行销售，欧洲的知名建材超市像德国的OBI（欧倍德）、乐华梅兰、安达屋、B&Q，北美地区基本是Homedepot、Lowes这样的大建材市场来完成，他们有严格的采购前的质量评估系统和较强的售后能力。第二，欧美的建材销售不依赖于品牌在商业上塑造知名度，主要是依赖完善的第三方市场认证系统，认证也是保障产品质量信誉的方式。所以在发达国家只要是有认证，在大建材市场销售的，可以按需选择，品牌差异不大。

Gong: How to choose the solution of housing system in developed countries? Like HVAC?

宫：那么在发达国家又是如何选择住宅系统解决方案的呢？例如暖通空调之类？

IS: This will need us to talk about the professional design and construction systems in developed countries. For example, the threshold for the use of underfloor heating in Europe and America is high. First, find a professional design organization, which is a very expensive service, then purchase materials and find licensed construction personnel. This series of services are extremely expensive and often compromise in terms of cost, Generally, the simplest equipment is selected according to the required functions. Of course, such service can ensure the effect of the system without considering the high cost. Therefore, the attention to the brand in the HVAC system is not high, mainly the design and construction team is selected in terms of price and service cycle.

IS：这个就要讲一下发达国家的专业的设计、施工系统了，例如地暖在欧美使用的门槛较高，首先要找一个专业的设计机构，这个是一个很昂贵的服务，然后去采购材料、再找到有执照的施工人员进行，这一系列的服务，都是极其昂贵的，往往在费用上就会妥协，一般按照所需的功能，选择最简单的设备来完成，当然在不考虑昂贵费用的情况下，这样的服务是能够保障系统的效果，所以在暖通系统上对品牌的关注度也不高，主要是在价格和服务周期上选择设计和施工团队。

Gong: What suggestions do you have for Chinese customers to choose brands from developed countries and regions in Europe and America?

宫：对于中国购买者选择产地为欧美发达国家地区的品牌您有什么建议？

IS: I think if you like the brand of building materials in developed areas, you must like the quality of this brand and install it in the building to improve the quality of life. However, brand screening needs to be carried out in the process of marketing, which itself is a more complex work. When purchasing building materials, if it is the expectation of quality, it depends on whether the brand has the certification for this product in its country. You can check with the certification authority through the certificate, including DVGW in Germany, WRAS in the UK, NF in France, AENOR in Spain, WaterMark in Australia, UPC, NSF, UL in the United States, CAS in Canada, etc, The second is to see whether it is sold in the main building materials markets in the country of origin, such as OBI in Europe, Adeo, Homedepot and Lowes in North America. These are all ways of inquiry.

IS：我认为喜欢发达地区建材品牌，一定是喜欢这个品牌的质量，安装在建筑内提高生活的品质，但是市场销售的过程中需要进行品牌的甄别，这个本身就是一个比较复杂的工作。购买建材的时候，如果是对质量的期望，那么要看这个品牌在他所在国家是否有针对这个产品的认证证明，可以通过认证证书去认证机构查询，其中德国的DVGW、英国的WRAS、法国的NF、西班牙的AENOR、澳大利亚的WaterMark、美国的UPC、NSF、UL、加拿大的CAS等，其次就是看他在原产国的主要建材市场是否销售，比如欧洲的OBI、安达屋、北美的Homedepot、lowes，这些都是查询的方式。

Gong: What suggestions do you have for Chinese customers to choose HVAC, water purification and fresh air products produced in developed countries and regions in Europe and America?

宫：对于中国购买者选择产地为欧美发达国家地区的暖通、净水、新风等您有什么建议？

IS: In terms of system service, we should pay more attention to the design ability and construction ability of service institutions, or whether they have the ability of long-term after-sales service. At present, there is no certification as a basis in China. Personally, I suggest focusing on the quality, brand and certification of equipment installation auxiliary materials, because this is also the guarantee of system operation quality, and then the design ability, Whether there is a professional design team and whether they understand the design standards can also be used as a reference for judgment. The most important thing is the ability of construction and after-sales, whether the construction meets the Chinese or international construction standards, and whether the acceptance is based on the use results. As for the brand, China is currently the largest manufacturing country in the world, most Chinese brands also have good quality performance and have achieved good market performance in developed countries. They should be selected according to actual needs.

IS：在系统服务上，其实应该更关注服务机构的设计能力和施工能力，或者是不是有长期售后服务的能力，这个在中国目前还没有认证作为依据，我个人建议重点关注设备安装辅助材料的质量、品牌、认证，因为这也是系统运行质量的保障，然后是设计能力，是否有专业的设计团队，是否了解设计标准，也可以作为判定的参考，最重要的就是施工和售后的能力，施工是否符合中国或者国际施工标准，在验收的时候是否是针对使用结果进行验收，至于品牌，中国目前是全球最大的制造国家，多数中国品牌也有较好的质量表现，在发达国家也取得了不错的市场业绩，要根据实际需求进行选择。

At present, the demand of China's indoor environment and building materials market is still on the rise. Under the huge market opportunity, some brands with poor publicity and authenticity inevitably appear. In this way, we must have the ability to judge in order to obtain safer and higher quality products, and it is more difficult to judge the system service.

目前来看中国的室内环境和建筑材料市场的需求还处于上升期，在庞大的市场机会下不免出现一些宣传和真实性不好的品牌，这样就要有判定的能力，才能得到更安全和更高品质的产品，在系统服务上的判断就显得更加困难了。
