For the purpose of analyzing urban energy consumption, this paper focuses on the development of the prediction model for electricity consumption in urban residential area through correlation analysis between urban residential blocks and its characteristics. The research investigates through 27 residential blocks with a total of 1386 residential town houses in Tainan, Taiwan. Among them, 599 houses are useful samples. The conclusions are as follows. 1.The annual whole average electricity consumption per floor area is 33.29 kWh/m2‧yr. 2.With respect to the eletricity consumption density, the two story building is 1.56 times larger than the building with five stories. Considering azimuth, the west-facing houses are 1.33 times the average electricity consumption of those facing north. 3.The whole air-conditining electricity consumption accounts for 15.56% of the total. Besides, the research also developed a simplified prediction model for electricity consumption of residential blocks. For pure residential buildings, the deviation of average predicted data is about 10.14% to 15.62% and the coefficient of relevance is up to 0.78 among the predicted and the real data. The electricity consumption of residential blocks with west-east major axis is truly less than that of north-south axis. According to the average value among the research samples, the amount of the energy saving can reach 12.89%. With energy saving respective, this research can be regarded as a reference to the street block design in urban planning.
