Abstract
Concrete core activation (CCA) systems can efficiently utilize low-temperature sources while maintaining comfortable indoor conditions. ISO 11855-4 describes the modelling method for the dynamic hourly simulation of CCA. This model recommends constant internal heat transfer coefficient by radiation and does not provide guidance on convection. This paper presents a computer implementation of the ISO method and measurements conducted in a passive office building with CCA. The discretisation algorithm was proposed, the simulation programme was developed, and the convergence analysis was performed. Simulations were performed for constant and varying convective and radiant heat transfer coefficients. The mean absolute error (MAE) ranged from 0.28°C and 0.18°C (floor temperature) to 0.37°C and 0.45°C (air temperature) for the first and second model, respectively. All temperatures indicated an underestimation with a maximum mean bias error (MBE) of –0.42°C and –0.29°C. Implementation of time-varying internal heat transfer coefficients improved the accuracy of the results obtained. © 2025 International Building Performance Simulation Association (IBPSA).
