I’m an Italian student at the University of Pisa. Due to the fact that I’m doing my thesis through Ladybug and Honeybee I had to verify Ladybug+Honeybee data reliability. Down here you will be able to check them. The analysis has been run for Pisa during May, September and January.
Reading the results I have extracted from the softwares I can say they are quite good. The data pattern is fine and the most difference can be found on the north exposition. This is because of the Italian Regulation Data that you will find inside data_matching.gh takes the values through the Liu-Jordan model, considering different mode to build sky dome (isotropic). Indeed Ladybug or Honeybee use an anitropic sky model Perez-based.
Pleased to know your opinions,
PS: I have internalized data and turned off the radiance tool toggle to not choke your pc as you open the file.
