Weather files and DDY files

Hi @chris,
Full explanation and now i understand the dilemmas.
I don’t really know how often in the whole world the DDY is missing or is not populated with the necessary data. For now i know that the DOE source files for my country provide just one right location. Saying that the OneBuilding source is fine. I didn’t check the differences for the same location but i can assume they are not really significant (i will check though). The solution i was thinking, before your above response, is copying the DDY from OneBuilding to the DOEs.
After your explanations and alternatives i think that the last option (creating a component to create the DDY) is the best. The reason is that users will be aware the original data is missing. Saying that, for most users the automatic DDY creation will be te preferable one. In such case i will also add the warning explaining what was done.
This 2 will cover, i think, both ends of the bridge: general users - more “experts” ones.

What do you think?

Thanks again,
-A.
