The relationship between the building energy monitoring system and the building energy management sy

The former is only monitoring and measurement, and the latter is managed on the basis of monitoring and measurement data. In fact, this is just a statement, many companies these two systems are actually a set of systems, if you only monitor and do not manage, it is one less system for management and related control devices, so that the cost is less.

Zhengzhou Chunquan building energy consumption monitoring system uses on-site metering automatic collection device to realize data aggregation and statistical analysis of water, electricity, gas and heating (air conditioning) in each area of the building through network technology. Centralized and automatic control of relevant energy-consuming equipment is carried out through optimization calculations, so as to achieve the purpose of energy consumption statistics, energy audit and building energy saving. You can go to Chunquan** to find out, and other peers are also okay.

There are very few companies or units that only monitor and do not manage, otherwise there is no point in monitoring.

Building energy consumption monitoring system refers to the hardware and software system that realizes the best monitoring and dynamic analysis function of energy consumption of key buildings through the installation of classified and shared energy consumption metering devices for office buildings and large public buildings, and the timely collection of energy consumption data by means of remote transmission.

Building energy management system refers to the rational distribution, operation and management of energy (such as water, gas, electricity, etc.) used in office buildings and large public buildings.

The relationship between the two is that the building energy consumption monitoring system monitors the energy of the building, but does not manage it; The building energy management system manages the energy of the building without monitoring how much it uses and how much energy consumption value it reaches.

According to the survey of relevant data, the current carbon emissions of industry, transportation and construction can reach 80%-85% of all total carbon emissions, of which the resources and energy consumed by the whole process of the construction industry account for 50% of the world's total energy consumption, and the energy consumption of buildings in China accounts for about 28% of the total energy consumption of the whole society, while the growth rate of energy production is far less than the growth rate of energy consumption of buildings.

Through real-time monitoring of the energy medium of the building section wheel, such as water, electricity, heating, gas and other energy consumption and the energy consumption level of each classification and sub-item, the operation management and monitoring are carried out, and the manager can make horizontal comparisons with similar buildings and design standards according to the system data accumulation and statistical analysis, assist in tapping the energy-saving potential, and help the energy department to measure and judge the actual effect of saving and burning wild energy, so as to achieve the purpose of energy conservation and emission reduction, improve the whole life cycle of the building, and create a comfortable and convenient environment.

1. Managers do not understand the actual energy consumption level of the building equipment, lack of detailed energy consumption data accumulation, and lack of scientific energy consumption level evaluation methods.

2. The designer does not understand the actual energy-saving effect of various energy-saving technologies. Some energy-saving technologies are abused; Although the effect is remarkable, but the concept is not loud enough energy-saving technology means can not get due attention, some architectural design uses a large number of so-called energy-saving technology, but does not receive the desired energy-saving effect.

Therefore, it is necessary to establish a standardized sub-item energy consumption monitoring system, and the Yunji energy consumption monitoring system can monitor the energy consumption level of each sub-item in real time, realize the best operation management and monitoring, and compare with similar buildings and design standards horizontally, assist in energy-saving diagnosis, and measure the actual effect of energy-saving transformation, so as to finally reduce energy consumption, improve system operation efficiency, extend the service life of equipment, improve personnel comfort and work efficiency, etc.

Public buildings due to their nature is basically the need to be on call 24 hours a day from the aspect of energy saving, different periods of the first amount of energy is different, so the energy consumption is also different, in the first amount of less or no one when there is no one, energy saving, has a great role in protecting equipment and the environment.

From the perspective of safety, once these public buildings fail, small problems cause congestion and other failures, and large problems, there may be situations that affect personal safety.

The significance of the energy consumption monitoring system is to monitor 24 hours a day, find fault problems in time, help speed up the maintenance progress, and save resources, so the energy consumption monitoring system is extremely important!

China's total annual power consumption of public buildings accounts for 10% of the country's total consumption, take the appropriate public building energy consumption monitoring system software for supervision and analysis, the installation of suitable energy-saving equipment will greatly reduce costs, gather energy consumption monitoring system for public buildings energy consumption monitoring program is as follows.

Answer: Meaning: 1

Managers do not understand the actual "energy consumption level" of each equipment system in the building: the public building itself lacks detailed energy consumption data accumulation; lack of effective exchange of energy consumption data between buildings; There is a lack of scientific evaluation methods for energy consumption levels. 2.

Designers do not understand the actual "energy-saving effects" of various energy-saving technologies: some energy-saving technologies are abused; Although the effect is remarkable, but the concept is not "loud" enough, the energy-saving technical means can not get the attention they deserve; Some building designs incorporate a number of so-called "energy-saving technologies" that do not achieve the desired energy savings. Therefore, it is necessary to establish a standardized sub-item energy consumption monitoring system, real-time monitoring of the energy consumption level of each sub-item, to achieve first-class operation management and monitoring, horizontal comparison with similar buildings, design standards, etc., to assist in energy-saving diagnosis, and to measure the actual effect of energy-saving transformation, so as to ultimately reduce energy consumption, improve system operation efficiency, extend the service life of equipment, improve personnel comfort and work efficiency, etc.

Precautions: 1) The definition of sub-item energy consumption should be unified and standardized to ensure that the objects of horizontal comparison are consistent; 2) When the actual distribution and installation of electricity meters, the sub-item distribution and separate meter installation should be done as far as possible to avoid the data measured by a meter as mixed sub-item energy consumption; 3) The data collection time step should not be higher than 1 hour, so as to provide a guarantee for hourly data analysis; 4) Improve the stability of the whole system, including data collection, transmission, storage, display and other links to ensure data quality;
