Re: [EnergyPlus_Support] Re: How to change the solar radiation calculation model in Energyplus
The .EPW file can be edited by opening it with the weather converter utility and convert to CSV, then can be edited in excel and changed back to .EPW with the weather converter.
I think that your pyranometer readings should be close to the value found for GHI at that hour. The hourly data is from various years over the averaging period so it may not be the same.
There are two approaches you could take.
Primary EnergyPlus support is found at:
- Use actual meteorological year data for the year of measure, or the closest year available.
- Use your actual solar measurement data to replace the hourly averages for those hours. (I think that if you only enter GNI that the weather converter will calculate direct and diffuse for you- but you should check the documentation to be sure.)
