The energy management system is developed on the basis of the itemized measurement of building energy proposed by Professor Jiang Yi, an academician of China Academy of Sciences, which is in line with the development direction of China from extensive economic mode to refined management. Therefore, the concept was quickly put forward by the national leadership, and it took only two years from the beginning of the experiment in 2006 to the determination of the basic terminology concept in 2008. In 2009, after the relevant national ministries and commissions began to issue corresponding standards and policies, many companies doing energy management systems quickly appeared in China. These companies can be roughly classified as follows: 1 R&D type. Such companies are owned by some scientific research institutes or core personnel who undertake the research and development of energy management systems of the state or ministries; 2 the same type. Most of these companies are companies that do data acquisition systems. Technically, they apply the existing data acquisition system to the energy management system, with only a few changes. 3 hardware type. These companies all have data terminal acquisition hardware. If they are familiar with data acquisition, the software system will directly purchase the system of the first type enterprise.
Generally speaking, each has its own advantages, but people who really understand this industry know that energy management system is actually a service product, that is, data analysis is the real core. Therefore, it is R&D enterprises that can really make full use of energy and achieve management results. However, these companies are still relatively small (the industry has just started), while the other two companies have been established for many years and their products are diversified, so the resources and scale of the company are relatively large.
In addition, there are two schools of energy management system in China: 1 Tsinghua Energy Conservation Center and Shanghai Academy of Engineering. What's the name of that company in Tsinghua (I forget the name)? The one in Shanghai is Daxi Energy Technology Co., Ltd.
