Energy Planningoriented Simplified Models of Envelope Dynamic Load Prediction for Individual Buildings

Abstract:

A simplified model of envelope HAVC load prediction for individual building was proposed, in which the number of input parameters was reduced to six, and prediction accuracy guaranteed. This building thermal dynamic model was established with the open source library of Buildings Modelica Library developed by Lawrence Berkeley National Laboratory. The linear aggregation method was used to reduce the order of simplified model, in order to accelerate calculation. This simplified model makes possible the fast calculation of HVAC load for each individual building, and hence provides the method basis to expand to the regional scale simulation. Finally, discussion was conducted to expand the method in regional dynamic load prediction in the future.
