The energy management server periodically requests data stored in the data server, uses the processed data to identify energy consumption in the building, and provides analysis information and performance evaluation information for optimal operation of the facility.

At this time, the process of determining the energy consumption and deriving the optimal operation of the facility through the energy management server will be described in detail with reference to FIG.

The data processing unit of the energy management server calculates energy consumption by using a SQL agent for data collected every 15 minutes from the data server through the DB interface (S41).

At this time, the process of calculating the energy usage, the daily energy consumption by 15 minutes by the data processing unit collected in 15 minutes and the 15 minutes energy consumption divided into 96 data per day through the SQL Agent for daily energy Calculate the usage.

Subsequently, monthly and yearly energy usage may be calculated based on the daily energy usage.

On the other hand, after calculating the energy consumption, the data setting unit performs a point setting and mapping (Mapping) operation for the data transmitted from the data server, and sets the classification and classification of the points (S42).

In this case, the data setting unit configures and registers a point DB to perform configuration of performance evaluation items for performing performance evaluation, configuration of an energy tree for energy aggregation and analysis, and registration of calculations for calculation of calculations.

For example, the division for each use is defined as a heat source, a heat transfer, a hot water supply, a lighting, an outlet, a power source, and the like.

In this case, the definition of the use classification is performed with reference to the above-described predecessor (S10). That is, it is possible to analyze the system diagram of the power distribution panel through the review of the power distribution panel schematic diagram carried out in the preceding work and the review of the MCC / distribution panel, and to analyze the electric power DM to define the classification of the facility by usage.
