Because of the high humidity will affect the temperature of the body to feel, so this study based on the climate and environment in Taiwan, collecting energy data to be used from National Taiwan University student dormitory, reference to the Energy Star model of US energy use benchmarks, deduced from the primary energy use efficiency estimate models of National Taiwan University student dormitory to establish the energy use benchmarks of Taiwan localization. 　　In this paper, based on the collection of questionnaire from National University dormitory energy use data. When the parameters are a linear correlation analysis, we found the relevant of Soure Energy is higher than Energy Use Intensity (EUI), therefore this study based on Soure Energy. To consider the humidity, present study use HI-CDD, enthalpy difference (ED) as a parameter of a cooling load linear correlation analysis; when the humidity is not considered, R2 is 0.732195. Humidity in HI-CDD as a parameter, R2 is 0.775933; humidity in the enthalpy difference as a parameter, R2 is 0.747091.From the three data comparison, after considering the humidity, the correlation is improved, proof humidity considerations have a positive impact on energy use analysis. Collecting 33 student dormitories energy use data, we can establish the estimate energy efficiency model of the dormitory in Taiwan; by the way, we can already assess the scores of dormitory energy use by this estimate model, dormitory energy use of the scores. Using HI-CDD, ED estimate model parameters respectively to establish a comparison and found that these two parameters taking into account the temperature and humidity,it will be a consistent rationality. 　　Finally, Using a south of dormitory as a Ecotect model to simulate, we found that direction change will affect the hot environment, but there is no direct impact on the amount of energy used, mainly due to the higher proportion of electricity in the dormitory equipment. It was found that in the summer, Air exchange rate will be converted from 1 simulated 0.5, it should be the high Air exchange rate, then consume more energy; contrarily, in the winter, there will bean energy-efficient phenomenon, it may be the outside air temperature is lower than it is in summer,and it can reduce the energy consumption of the heat exchange; for this reason, it reduce the burden on air-conditioning equipment.
