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
