Due to the low thermal transmittance of modern building envelope components, increased cooling loads, large areas of transparent elements, and climate change, indicators of indoor comfort and energy use for the operation of technical building systems must be determined through dynamic thermal response modeling. As part of this study, a dynamic model was developed following the methodology defined by the Energy Performance of Buildings Directive (EPBD) and the corresponding technical standards. The model is based on the simultaneous solving of an energy balance equation system at thermal nodes. It was successfully validated using a commercial numerical modeling tool for building thermal response and compared with reference cases from the EPB technical standard. The validation included both free-running and thermostat-controlled building operation. The model was further enhanced with developed algorithms for shading control and dynamic modeling of natural cooling through ventilation, representing a significant advancement of the standardized dynamic modeling method within the EPBD framework.
