This paper investigated the uncertainty introduced in Climate-Based Daylight Modelling (CBDM) by two solar radiation and one luminous efficacy models, chosen among those often found in Building Performance Simulation (BPS) tools. Analyses were carried out for two locations, Camborne, UK, and Sonnblick, Austria. Irradiances and CBDM metrics were found to be more accurately predicted by the model used for IWEC climate files, as such model can be optimised for each specific location. The model used within CIBSE climate files was found to be less accurate. In both cases, the direct component prediction exhibited significant errors.
