Indoor air temperature modelling: Thermal retrofitting of historical building

In this paper, a newly formulated model for simulation of indoor air temperature is presented. The model combines diffusion model for description of heat and mass transfer through the wall assembly and the indoor air temperature model. Both models are interconnected and exchange data during the simulation. The model capability is demonstrated on a simple case study, in which a historical masonry made of sandstone is analyzed before and after thermal retrofitting. The result showed good performance of the model as well as possible ways for model extension and utilization.
