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.
