Excessive Error in Simulated Roof Surface Temperature: Incorrect Climate Parameters?

[Suki]

I am using my own measured weather data in WUFI PLUS. Since my task involves heat transfer calculations, I applied the parameter settings from the attached file when configuring the weather data file.

However, after running the simulation, I noticed a significant discrepancy between the simulated surface temperatures and the actual measured temperatures. The actual temperature reaches a maximum of 70°C, while the simulation result only goes up to 50°C. Therefore, I would like to inquire whether this issue might be due to incorrect settings in my weather data file.

Best regards,
