Embodiment
[0017] The research data comes from the electricity consumption of various buildings and air-conditioning units in an office park from July to September. The sub-item metering mainly includes the office building master meter, the 19th floor master meter, the C building master meter, the D building master meter, and the central air-conditioning unit. General table and 4 air conditioner group tables, etc., figure 1 It is a flow chart of the method of the present invention.
[0018] Since the obtained power data is the reading of the meter every minute, it needs to be converted into power data at intervals of 15 minutes. The processing method is to divide the ammeter readings every 15 minutes into one group, subtract the readings of the first minute from the ammeter readings of the 15th minute and divide by the time to obtain the average load data during this period. In order to clearly show the change trend of the load, the electricity consumed in 15 minutes is used as each poi...

The invention relates to a building comprehensive energy efficiency analysis method based on subentry measure. The building comprehensive energy efficiency analysis method is characterized by comprising the following steps: 1) obtaining the daily electricity consumption data of a building, and carrying out preprocessing to complement a missing numerical value and damage data, wherein the electricity consumption data comprises daily total electricity consumption, the daily total electricity consumption of electricity consumption equipment and the daily electricity consumption and the daily meteorological temperature data of each electricity consumption equipment unit; 2) adopting a K mean value algorithm to carry out generalization processing on the daily electricity consumption data to obtain a generalization data set; and 3) adopting an FP (Frequent Pattern) growth algorithm to carry out association rule analysis on the generalization data set, and obtaining relevance between the total energy consumption and the meteorological temperature of the building and each piece of electricity consumption equipment. Compared with the prior art, the building comprehensive energy efficiency analysis method has the advantages of advanced algorithm, obvious effect and the like.
Description
technical field [0001] The invention relates to building comprehensive energy efficiency analysis, in particular to a building comprehensive energy efficiency analysis method based on sub-item measurement. Background technique [0002] Building energy consumption accounts for about 40% of the world's total energy consumption and is one of the important sources of greenhouse gas emissions. The power consumption of buildings in my country accounts for about 27% of the total power consumption of cities and towns in the country, and more than 95% of buildings are high-energy-consuming buildings, and the unit building energy consumption is 1.5 to 2 times that of developed countries. In the future, with my country's economic development and industrial restructuring, the proportion of building energy consumption will continue to rise. In order to cope with the energy crisis and environmental deterioration, the energy conservation work of buildings has received important attention ...
