KNX在中国和欧洲的住宅及小型商业楼宇智能家居市场是主要的通讯协议方式年五月 2017

    BSRIA在2017年1月发布了最新的‘住宅及小型商业楼宇的智能家居市场调研报告’(以下简称为‘报告’)。报告由中国、法国、德国、荷兰、北美和英国等国家的独立调研报告组成,调研结果预测2017年住宅及小型商业楼宇的智能家居全球市场总体将有20%的增长。其中增长最快的预计是英国市场(29%)。报告把市场细分为独立和整装产品市场,而且分别算出系统集成(增值服务)和售后服务部分的销售额。

    2017年全球市场容量预计为158 亿美元,美国仍然会是最大的单一市场,占全球市场容量的29%。即使美国市场已经很成熟,但预计增长幅度仍会与全球增长率20%同步,而独立产品将是增长最快的部分,增长率预计有27%。

    报告还预测产品和系统集成的销额将快速增长,但是由于市场还处于萌芽期,售后服务及维护部分市场销额将维持较低的水平。

    调研报告显示垂直市场最大的领域是豪华别墅,占整个市场容量的25%。第二和第三大领域分别是办公楼和酒店,共占市场容量的23%。

    报告中也提供直到2021年的未来展望,预测届时全球市场容量将扩大到298亿美元。

    关于通讯协议,调研结果显示在美国私有协议占市场主导,反之欧洲和中国市场中KNX的普及速度明显加快。传统的KNX有线连接方式由于在部署方面的不便,局限于安装在新建建筑中,而2010年面世的KNX RF(无线方式)版本明显加大了其市场份额,成为了排在私有协议和Wi-Fi之后的第三大协议方式,但它有一个优势,就是可以与KNX有线产品兼容。

    在德国的整装解决方案市场中KNX占据主导地位(56%的份额),它是在德国和欧洲的主要智能楼宇供应商的大力推动下迅速发展起来的。私有协议仍然有着不可忽视的市场份额,而还没有任何其他协议方式在份额上凸显出来。

    在英国的整装解决方案市场中,没有一个通讯协议占明显大的份额。每一个协议方式都有各自的优势和弊端,且很多安装商会结合多个协议方式。BSRIA的调研发现KNX在英国整装智能系统部分占据27%的市场份额。

    在法国KNX仍然是非私有协议中最流行的,占有32%的市场份额,在法国KNX是有很长历史的通讯协议方式,但需要指出的是,私有协议在法国也是有一席之地的。私有协议可能有着在设备上不增加额外费用的优势,且给制造商最大的自由空间,但它与其他系统集成起来尤其复杂。行业里还没有对公开标准的一个共识,且通讯汇流问题仍然是智能楼宇市场发展的一个障碍。法国的主要能源供应商EDF决定向Linky智能测量计提供通过KNX接口传输测量数据的其他可能性,因此预计KNX在法国的重要性将提升。

    私有协议(15%)在荷兰的表现很好,而KNX在整装智能家居系统的市场份额达 34%,因此成为荷兰家居和楼控的标准。

    有线系统在中国整装智能系统中占整个市场的绝大部分。在总体整装智能家居市场中,将近38%使用私有协议,且约有42%是KNX系统。在中国KNX协议构成了‘智能家居安装的欧标’,成为了2013年以来唯一被认可的家居及楼控的国标(GB/T20965)。中国大量协议方式用在无线产品,然而绝大部分是包括Wi-Fi的独立智能家具产品或子系统。

    Wi-Fi的缺陷在于消耗更多能源,且家里的设备通过Wi-Fi工作会削弱网络连接。

    现今,大多数住宅和小型商业楼宇都会对供暖或制冷及通风系统进行控制。这些控制一直都处于最基本的阶段。然而,有一种变化正在上演,越来越多的住宅和小型商业楼宇中开始进入‘智能’产品和系统,如酒店、餐厅和老年生活辅助护理院等。

KNX is the leading communication protocol in the European & Chinese Smart Homes/Light Commercial Market

 

BSRIA is pleased to present the results of its latest Smart Home/Light Commercial market study produced in January 2017. The study, which consists of individual country reports on China, France, Germany, Netherlands, North America and UK, is forecasting a total global growth of 20 per cent in the Smart Home/Light Commercial market in 2017, with the largest growth being predicted for the UK market with a growth rate of 29 per cent. The study segments the market into stand-alone products and whole home products and also analyses the value of system integration (value add) and service and maintenance.

The total value of the global market is forecast to be $15.8 billion in 2017; the US market remains the largest single market forecast at 29 per cent of the total market value. Despite the maturity of the US market, the growth forecast is expected to be in line with the global increase in value of 20 per cent, with stand-alone products being the segment showing the largest growth at 27 per cent.

The study is also forecasting rapid growth in sales of both products and system integration, but due to the infancy of the market, a lower level of sales for service and maintenance.

The reports show that the largest individual vertical sector is luxury villas accounting for 25 per cent of the market value; the second and third largest segments, offices and hotels respectively, represent a combined total of 23 per cent of the market.

The reports provide an outlook until 2021 when it is forecast that the total global market will be worth $29.8 billion.

In terms of communication protocols, whereas the market in North America is dominated by proprietary protocols, the study shows a significant increase in the penetration of KNX in Europe and China. The typical KNX wired solution has traditionally limited its deployment to new-built installations: the launch of the KNX RF (wireless) version in 2010 has enabled it to gain a significant market share, placing it in third place behind proprietary communication protocols and Wi-Fi, but with the advantage that it can be integrated with KNX wired products.

In Germany the whole home solutions market is heavily dominated by KNX (with a share of 56 per cent), which was developed largely under the auspices of major German and European smart building suppliers. While proprietary protocols still have a significant share, none of the other protocols have yet gained critical mass.

The whole home solutions market in the UK is not dominated by any one communication protocol. All protocols have their own strengths and weaknesses, and many installations will incorporate more than one protocol. The BSRIA study found that KNX has a 27 per cent market share in the UK’s whole home smart systems segment.

KNX remains the most popular of the non-proprietary protocols in France with 32 per cent of the market. It is a long established communication protocol in this country, but it should be pointed out that proprietary protocols are also very strong in France. Proprietary protocols may have the advantage of not adding additional costs to the devices and give the biggest freedom to the manufacturer: however, they seriously complicate the integration with other systems. The industry has not found a consensus on the open standard yet and the convergence issue is still a threat to the progression of the smart market. Since EDF, as the leading energy supplier in France, took the decision to offer among others the possibility to transport metering data via a KNX interface in its Linky smart meters, the importance of KNX is expected to increase in France.

Proprietary protocols (15 per cent) are well represented in the Netherlands, but KNX has a market share of 34 per cent in whole-home smart home systems, thus becoming the standard for home and building control in the Netherlands.

Wired systems account for the vast majority of the overall market in China for whole-home smart systems. Of the total whole-home smart home market, nearly 38 per cent uses proprietary protocols and about 42 per cent was accounted for by KNX systems. The KNX protocol constitutes a “European standard for smart home installation” in China, which has become the only approved Chinese standard (GB/T20965) for Home and Building Control in 2013. A large number of protocols are used in wireless products in China, however, mostly for stand-alone smart products/subsystems, including Wi-Fi.

Wi-Fi’s disadvantage is, however, that it consumes more energy, and devices working through Wi-Fi can slow down internet connectivity at home.

Today, most homes and light commercial buildings have some control over their heating or cooling / ventilation system. These controls have traditionally been very basic. However, there is a new evolution underway which is starting to put “smart” products and systems into an increasing number of homes and light commercial buildings, such as: hotels, restaurants and elderly care homes for assisted living.
