Heat transfer through the building envelope dynamic models and validation

The research presented in this paper is part of the contribution to the European project INDIGO, which aims to develop a more efficient, intelligent and economical competitive generation of District Cooling (DC) systems by improving the existing planning, control and management tools. The project has received funding from European Union’s Horizon 2020 research and innovation programme under grant agreement n. 696098. The proposed solutions for DC systems will be installed in the Basurto Hospital campus (Bilbao). The HVAC systems and some buildings have been modelled. The present paper focuses on the building modelling phase of the heat transfer through a wall. Output results and measured data have been compared and discrepancies between them have been evaluated through specific indexes. The results of a sensitivity analysis to evaluate how much the input parameters or the used algorithms affect those indexes are here presented. As further development of the research, the model of the building was integrated with the model of the AHUs, completed with the model of the cooling distribution and production, in order to complete the whole model of the DC system
