[EnergyPlus_Support] Re: Pools in E+





Maxime,

James Dirkes posted a spreadsheet with his message: http://tech.groups.yahoo.com/group/EnergyPlus_Support/message/29467

I think that if you receive every email from this group you'll have received his message with the spreadsheet attached.
If you receive the daily digest email, as I do, then you don't receive attachments. If I'm not wrong, in the near past you could get the attachments from the group website, but now you just see a rectangular at the messages end with the attachment name in it (no link).
So, if you want James' spreadsheet you'll have to ask him.

Rui
