It's basically an excel spreadsheet, not that user friendly. But in my experience, if you're going for high energy efficiency, that's the professional way to go.

Just solar panels?<BR /> <BR /> In that case I would have zero CO2 emissions?<BR /> <BR /> Thank you for the reply.</R></DIV> Thu, 21 Apr 2011 08:40:21 GMT https://community.graphisoft.com/t5/Collaboration-with-other/Using-only-Solar-panels-for-heating-and-hot-water/m-p/206482#M26032 Anonymous 2011-04-21T08:40:21Z https://community.graphisoft.com/t5/Collaboration-with-other/Using-only-Solar-panels-for-heating-and-hot-water/m-p/206483#M26033 any reply please?
