How to simulate giving the weather condition heavy raining.

asked 2020-10-28 03:36:35 -0500

I have provided the measured values and modified the weather file for energyplus simulation. results are not matching with experimental. Apart from weather file update how can I define heavy rain in .idf editor.

Thanks Amith MG

What results are you referring to? You need to give more informations to clarify your question if you want to get an help

Thanks for your reply Alessandro Gober. I have measured data from model room experiment obtained during heavy rainy days for the room inside air temperature and outside weather data. I have used the measured data for generating weather file and simulate, but the results for room air temperature are not matching with the experimental one. Kindly advise.

This is a calibration model issue. You have it check all variable you re not totally confident (i.e. material constructions, ventilaztion -if natural- internal gains ...). "Heavy rain" should already be in the EPW file you created through DB, RH, solar radiation data, I guess (main EPW input data). Whitout these data you cannot say to have a weather data for calibration. Moreover rain indicator is used un EPlus only to modify external convection coefficient (from dry conditions to wet oconditions), so it has not a relevant impact compared to many other parameters involved in calibration
