Investigation and research on characteristics of the energy consumption of office buildings in Taiwan

Aiming at 29 office buildings in Taiwan, conducts energy consumption monitoring in over one year, and discusses the energy consumption structure and influencing factors. Analyses the energy consumption, energy consumption proportions and regressions based on the monitoring data, and establishes the energy consumption model, including the regression equations of the energy use intensity (EUI) and the demand use intensity (DUI), thus the power demand and energy consumption can be forecast. It is found that the user’s behavior and attitude affect the energy consumption greatly, which is reflected on the setting values of the indoor environmental temperature and illumination. The power consumed by power appliances was overestimated in the past and due to the effect of global warming, the power consumption proportion of air conditioning is on the higher side in spring, autumn and winter. Along with the intellectualization of office buildings and the increase of office equipment, the power consumption of the illumination and socket appliances tends to become larger, and the energy saving potential in this sector should not be ignored.
