Abstract EN
Luminous efficacy model uses solar radiation data to generate illuminance data, and its performance also depends on the quality of solar radiation data.
Various luminous efficacy models are reviewed and evaluated to select a universal luminous efficacy model.
Since most luminous efficacy models are fitted with specific local climate characteristics, the model that has the least locality as well as accuracy is a mandatory requirement.
Three representative luminous efficacy models are selected and evaluated with measured solar radiation and illuminance data from four worldwide cities.
It was found that all the evaluated models provide good predictions (over 0.96 R2 value) for both global and diffuse illuminance.
Among them, the Perez luminous efficacy model shows the highest performance in terms of accuracy and bias.
However, illuminance data prediction based on estimated solar radiation data is more common practice rather than those from measured solar data.
The performance of the selected luminous efficacy models is evaluated when recently proposed universal solar radiation model supplies predicted solar radiation data.
The result indicates that the quality of estimated solar radiation data has a much deeper impact on the performance of the luminous efficacy model.
Within the current limited technology and measured data resource, the consecutive processing of the modified Zhang and Huang solar model and Perez luminous efficacy model could provide the best option to predict both global and diffuse solar radiation and illuminance.
But, users of the model-based illuminance data should interpret their simulation results with the error (30%~40% in RMSE and ±6% in MBE) in predicting global and diffuse illuminance.
