Hello everyone! I'm Giandomenico, and I am a master student in Building Engineering at Politecnico di Bari. For my master thesis project I need to develop an EPW file of Bari. I have already gathered weather data but unfortunately, I have only global solar radiation. I've tried to split it, using Watanabe method but I've found some issues. So I have seen that Elements has its own equation to split global solar into direct and diffuse. Does anyone know what these equations are? Thank you in advance for answering me!
