Abstract: Insulating Concrete Formwork (ICF) walls consist of cast in situ concrete poured between two layers of EPS insulation. The system can achieve very low U-values and high levels of air-tightness. This paper investigates the inconsistency in simulation results provided by nine widely used Building Performance Simulation (BPS) tools when calculating the energy consumption and the thermal performance of buildings using ICF. The aim is to identify the impact that the various modelling methods have on the simulation results. There were significant inconsistencies in the simulation results, especially for the annual and peak heating demand. Moreover, among the different calculation methods, the surface emissivity, the infiltration rate and the specification of the internal gains were found to cause significant variations.
