Large scale enterprises in China Public buildings Energy consumption is huge. On the other hand, we also lack direct data to provide basis and reference for decision-making. The Notice on Printing and Distributing the Technical Guidelines for the Construction of Energy Consumption Monitoring System of State Office Buildings and Large Public Buildings (JK [2008] No. 114 (2008-06-24)) issued by the Ministry of Housing and Urban Rural Development implements the specific specifications for the energy consumption monitoring system. Therefore, it is necessary to establish a large-scale public building energy consumption monitoring platform to monitor the energy consumption of key buildings in key cities across the country in real time, and promote large-scale public buildings to improve the level of energy conservation operation management through energy consumption statistics, energy audit, energy efficiency publicity, energy quota and over quota price increase and other systems.
Necessity and Management Status of Establishing Energy Management System for Large Public Buildings
1. Necessity of Establishing Energy Management System for Large Public Buildings
Due to the rapid development of the construction market, the proportion of building energy consumption in total energy consumption in China is increasing year by year. Statistics show that large public buildings such as office buildings, apartments, restaurants and convention centers will increase significantly in the coming years. More than 90% of large public buildings in China are typical energy consumers. In the case of increasingly tight energy demand, energy conservation of large public buildings is an inevitable choice.
For large public buildings, it is difficult to understand the operation and consumption of power, water, heat and other related energy equipment in the building without installing an energy management system, which leads to a lot of unnecessary waste.
Therefore, the energy management system platform for large-scale public buildings is extremely urgent. The energy management and control system timely controls and effectively manages the energy consumption of buildings through software system informatization, greatly improving the energy conservation management level, so as to achieve the purpose of energy conservation. At the same time, the system can enable us to grasp the energy consumption changes of public buildings in a timely manner.
2. Energy management status of large public buildings
Building energy conservation is a worldwide problem. China's building energy conservation situation is backward, among which the energy consumption of large public buildings is a high-density area of building energy consumption, and waste is still serious, with great energy conservation potential. The following is an introduction to the energy-saving characteristics and management status of large public buildings brought by the construction network for reference.
At present, more than 70% of large-scale public buildings do not have full-time energy conservation management personnel, and the enterprise generally does not establish the corresponding energy management system, Yuanzhongrui Energy Management and Control System, to provide energy consumption management system for large-scale public buildings. Unable to grasp the overall energy consumption in time, and the operation and energy conservation of major energy consuming equipment in time. In general, the management of energy consumption equipment of most large public building owners is only from the perspective of safe use. It has become very urgent to establish an internal energy-saving management system of enterprises.
The HKST6000 building energy management system collects energy consumption data by means of remote communication transmission and other means through the classification of large public or commercial buildings and sub item energy consumption metering devices to achieve online monitoring and dynamic analysis of energy consumption of large public or commercial buildings (or building clusters). Specifically, classified energy consumption and itemized energy consumption are used for measurement and statistics. Classified energy consumption refers to the energy consumption data collected and collated according to the classification of main energy types consumed by government office buildings and large public buildings, including: electricity consumption, water consumption, gas consumption, heat consumption for central heating, cold consumption for central cooling, and other energy applications such as hot water supply, coal, oil, renewable energy, etc. Sub item energy consumption refers to the energy consumption data collected and collated according to the main use division of various energy consumed by government office buildings and large public buildings. Taking electricity as an example, there are four sub items: lighting socket power, air conditioning power, power and special power.
