Abstract: Energy efficiency in buildings plays a fundamental role. Therefore, it is crucial to design and test innovative building envelope concepts. A method to test it is using energy simulation software. However, it may be hard to test ideas in an existing building simulation software or library due to the barriers to develop and integrate new components. Thus, in this paper it is developed and validated a dynamic thermal zone model in Modelica language which is easily understandable and customizable by users. The model has been successfully validated against TRNSYS and the Twin Houses experiment monitoring data in free floating conditions.
