Abstract: The main objective of this study was to validate an easy to use in-situ measurement protocol for a dynamic coheating test. Indeed, regular co-heating test are not always suitable for the construction sector (mainly due to its duration). To achieve this, a significant number of measurements would have been necessary, under multiple conditions (climate, building types, protocols). As this was not practically feasible, simulations were used to produce virtual experiments, allowing the analysis of a wider variety of datasets than if real data would have been needed. Despite the limitations of such simulations, e.g. limited infiltration and thermal bridge modelling, the in situ measurement protocol CoDy was successfully developed and validated with actual in situ measurements.
