Gabor and Barry,

Thanks for looking this post.
I still used the build 5019, and I will follow Barry's suggestion to update. Thanks!
I will post the result on how it's going.
I saw Gabor's post works just fine on the West side opening.

Hi Everyone,

I updated my ArchiCAD 17 INT Edu to build 6004.
My result of the Solar Analysis didn't change.

I share my model here:

And these are my screen captures of solar analysis:

This is even still happened with new file, new model which start from a scratch.
I'm using the Strusoft Server for climate data.

Additional capture:

The sun shines on the North from rises to sets, but the radiation stops at noon.


*Excuse me for multiple posts, the forum didn't let me share multiple images.

Quote from EcoDesigner Star User Manual:

7.5.1 Climate Data Source
Choose an option for the source of the climate data to be used for EcoDesigner STAR.

• Download from StruSoft Climate Server: With this option, climate data are obtained from the StruSoft climate website, at http://climate.vipenergy.se.

All StruSoft climate data are created from NCEP Reanalysis data provided by the NOAA-CIRES Climate Diagnostics Center, Boulder, Colorado, USA, from their website at http://www.cdc.noaa.gov/.


Here comes the important part:

• Use ASHRAE IWEC, TMY, WTEC2 file: Click Browse to select and import data from analytic weather files obtained from an external source (from open source e.g.
http://apps1.eere.energy.gov/buildings/ ... r_data.cfm or purchased)

Note: Use analytic (“ideal year”) weather data whenever possible, as it usually represents a given location's climate better than climate data recorded in any particular year.


So you should be using analytical weather data (as recommended by Graphisoft) available from various sources (the above link is free, or open-source data) because that is the most accurate. As it seems the data you downloaded from the Strusoft Server is not accurate.
