【 摘 要 】

This paper uses the improved green CTTC model to explore the selection method of background temperature for long-term continuous calculation. A new method to determine the background temperature is proposed, and the feasibility of the method is verified by tested. This method not only improves the prediction accuracy of the model due to external meteorological factors, but also applies to long-term continuous calculations of one week or more. The consistency index d = 0.991, RMSE = 1.272?C, absolute error maximum = 5.6?C, relative error maximum 23.8%. 0.2?C ∼1.4?C is improved compared to the original calculation model.
