| Abstract |
In 2017, universities and colleges in the Korea spend an average of 218,774 toe on electricity and 125,516 toe on natural gas annually.
University campus energy consumption was second-highest among the building types. Because of the higher energy consumption, energy
saving planning becomes more and more important for university campus. However, insufficient energy use data accumulation has been a
significant barrier against fully understanding of energy use characteristics, and demand load features of campus buildings. This study aims to
develop and implement an energy audit protocol to tackle the questions of energy efficiency for education buildings. Many universities have
utilized a statistical data which may not fully capture the energy flow within the individual campus buildings. With the goal of overcoming
these limitations, a methodology to reveal the campus energy flow of demand load and the five standard prototypes of energy flow for
university building were developed. Taking H university for example, this paper proposes systematically how to make and analyze the
campus-level energy structure. As a case study, the 3-year energy data of the electricity, natural gas and geothermal usage of a H university
campus were analyzed by the descriptive statistics. The energy consumption structure in H university is summarized which can provide the
basis for energy saving measures. The methodology for university energy structure analysis presented in this paper can give inspiration for a
more thorough energy improvement approach, either for new single buildings or as renovation road-maps for a complete university campus. |
