Research on the Energy Consumption Reference Value of Commercial Office Buildings in Xi’an

Abstract:

Energy consumption reference values support the reference data for development of building energy efficiency potential. A uniform split model of energy consumption was established for calculating the item electricity consumption. Item electricity consumption are consisted by the electricity use of air conditioning system (chillers, chilled water pumps, cooling water pumps, cooling tower fans and end-use equipments), lighting system, indoor equipments and service equipments respectively. The data from site investigation was used to calculate the item electric energy use intensities (EUIs) in commercial office building. And these EUIs were used to identify the item energy reference value by two statistical analysis methods. The results show that the quadratic average EUIs which stand for the high level of energy consumption are lower than the mean plus standard deviation (SD) EUIs. Finally, the individual building (EUIs) can be compared with these reference values to evaluate building energy performance. And the item energy reference value is investigated in support of the retrofit of commercial office building.
