Evaluation of global luminous efficacy models for Florianópolis, Brazil
AbstractSeveral global luminous efficacy models have been tested with daylight-measured data obtained for Florianópolis, Southern Brazil. The models have been used with their original coefficients, given by the authors and also with local coefficients obtained when the models were optimized with the data measured in Florianópolis. The evaluation of the different models has been carried out considering three sky categories, according to a higher or lower presence of clouds.For clear sky, the models tested have been compared with a proposed polynomial model on the solar altitude, obtained by the best fit of experimental points for Florianópolis.It has been proved that the model coefficients have a local character. If those models are used with local coefficients, there is no model that works better than the others for all sky types, but that for each sky category a different model could be recommended.
