In-Depth Information
The energy consumption in buildings is generally related to time, climate, and the
number of people. For example, the energy consumption in office buildings is con-
cerned with the working hours, climate and number of people. While in commercial
buildings, it is related to the running hours, weather and passengers. The wind tunnel
center contains an office area and an experimental area. In it there are many high-
power devices. So it needs detailed data to analyze its energy consumption.
4.1
Application of Data Mining in Office Building
Energy consumption of office buildings can be divided into three categories: lighting
energy consumption, office equipment energy consumption and air conditioning
energy consumption. The energy monitoring and management system is used for
wind tunnel center to meter energy and then the measurement data is processed in
minutes, hours and days. Take the lighting electricity consumption as an example.
Fig.3 shows the daily energy consumption in a month, and Fig.4 shows the hourly
energy consumption in a day.

Hourly lighting electricity energy consumption data in office
From the figures we can see that there are some obvious rules on time. Fig.3 shows
that the energy consumption during 5 working days is much larger than that on rest
days which is almost constant but not zero. In Fig.4, energy consumption is generally
coincident with the working hours.
