Simplified Model of HVAC Load Prediction for Urban Building Districts

HVAC load dynamic prediction of building districts is fundamental in the field of urban energy planning. A new physical model of HAVC load prediction for the individual building is developed, with the open source library of BERKELEY LAB's Modelica Buildings Library in the environment of Dymola. On this base, this study explores the model further for the HVAC load prediction of urban building districts. The results shows that the method can ensure the accuracy of the results by the validation, and the calculation speed for building district is also very fast, as the input parameters for the HVAC load calculation of each building are reduced to six parameters.
