Abstract

As part of reducing greenhouse gas emissions, energy saving is required for buildings that consume a large amount of energy, including university buildings. However, because university buildings consist of several buildings having varying purposes, it is difficult to manage building energy for overall energy saving at the campus level. Therefore, this paper presents an intuitive presentation of building energy management direction by investigating the actual energy consumption patterns of university buildings at the campus level. Energy consumption data used are expressed using the Change Point Model, and energy consumption parameters such as energy use intensity, base energy use ratio, cooling sensitivity, and heating sensitivity are derived. Further, the energy consumption of buildings was classified into 16 patterns by using the energy consumption parameters. Each pattern was analyzed according to the building energy impact factors and the building energy management direction by applying the science and engineering buildings.
