After the industrial revolution, a variety of mechanized production entered people's daily life, and people's demands for comfort in life became higher and higher. With the rapid shortage of energy, the environment became worse and worse, global warming, the melting of Antarctic and Arctic glaciers led to sea level rise and other problems followed.
Starting from buildings, the transformation of energy contract management has gradually become the mainstream of development in the world. Although China is a rising star in this respect, it still has a large space for development compared with developed countries. From the current Public buildings In terms of energy-saving transformation projects, there are mainly the following problems:
1. Lack of energy consumption data
For a long time, energy consumption data collection belongs to the category of energy statistics. Before the 1980s, building energy statistics was not mixed with other statistics as a separate statistical category. With the increasing attention of the country to building energy consumption, the relevant part decided that it was necessary to make separate statistics on building energy consumption. At this time, building energy consumption was gradually independent from other statistics. For a long time, China's energy statistics mainly focus on industry, and the energy consumption statistics of buildings are in a blank state. Therefore, there is a lack of energy consumption statistics of buildings.
According to the above situation, it can be concluded that the energy consumption data statistics are mixed up, which leads to the inability to call out the required effective data from the statistical database when the energy consumption data needs to be analyzed. According to the current situation of energy-saving reconstruction of public buildings, the national government departments have not made Public buildings The energy consumption was classified and counted, and no special energy consumption investigation team was established to complete this work. At present, most of the energy consumption data come from the statistics of universities, scientific research institutions and experts. In terms of data statistics, there is no standard specification for reference in building energy consumption statistics, and the collected data cannot be compared.
Obviously, it is difficult to analyze and study the current situation of energy consumption with only a few scattered scientific research data. China needs to pay more attention to this aspect, establish relevant energy consumption teams, give financial, technical and management support, and establish a systematic energy consumption data statistics database. This work is difficult to implement, but it has a far-reaching impact on the follow-up research work.
2. Government investment and management
China's energy-saving renovation projects are still in the primary stage. From the perspective of the completed public buildings, the government currently has strict control over large-scale public building energy-saving renovation projects. The government is the main investor and manager of these projects. These projects under the control of the government mainly have the following problems:
1、 The government needs to provide funds for energy-saving transformation, which will exert certain pressure on the finance, and at the same time, it does not make good use of the private funds in the energy-saving market. At present, most of the transformation projects in China are the transformation of air conditioners and enclosures, and the unit cost of energy-saving transformation of these equipment and materials is high.
2、 The government has not set up a professional functional department to control the energy-saving transformation projects. The owner, investor and manager of private funds are usually the same unit. In terms of project implementation, the funds and management are very clear, and the owner will use less funds to produce energy-saving transformation effects. For projects invested by the government, the funds are generally allocated by the government. The implementers do not consider the pressure of funds, but only take the project as the main task, and there is no professional investment consultant. This situation often increases the actual cost of the project.
3、 There is no professional management team. The work of energy-saving reconstruction of public buildings is very complicated, which requires a professional management team to make overall arrangements. It is difficult for government departments to establish temporary management departments to make good control on all aspects of the construction, which makes it difficult to guarantee the project quality. In addition, due to the obstacle of instruction transmission and vague project handover, it is difficult to complete the project cycle in the controlled construction period, and the construction period is overtime. A series of problems, such as unreasonable allocation of construction resources, increased cost of management and control, etc.
3. Improve energy-saving service system
A complete energy-saving service system is composed of energy-saving service providers, energy-saving consumers, energy-saving market, energy-saving service management organizations, and laws and regulations generated by energy-saving services. Its purpose is to reduce the energy consumption of buildings and promote the development of energy-saving market. The energy conservation market in China is currently in its infancy, and the relevant system is not very complete.
Public buildings account for a large proportion in the whole energy conservation market. It is crucial to improve the management and coordination relationship among the government, owners and energy conservation service companies. Therefore, it is necessary to strengthen the leading role of the government, use the market mechanism, and take a variety of regulatory means to promote the development of energy-saving transformation of public buildings.
In order to better integrate public buildings with the energy contract management model, we must gradually break through the above three points, and expect more green public buildings of gastric cancer to appear in the shadow of smart cities.
