[EnergyPlus_Support] Re: Heating/Cooling load

["amyquartette" <amyquartette@xxxxxxxxxxx>]

Thank you very much for your suggestion.

For step 2 with the radiant system, I would not spend too much time to get a gross view of the heating/cooling load.And also because I am a beginner,I think I will try the idea of equipment gains with negative values.But I have still no idea of this method. 

I would appreciate for your advise! Thank you again.

I'm sure by the time I've written a macro that adds this zone equipment and connects it flawlessly to the plant with automatic branch creation and insertion into said plant mixer splitter list and branch lists, not to mention creating the interzone surface and reverse surface with correct dimensions and constructions, by the time I've coded such a macro, e+ will have brought out a update with an easy template. I know a baseboard radiator template exists, but if you're a begginer stay away from embedded concrete or panel systems. Instead, just use the equipment gains with negative values and be wary of dew point temperature in the zone not falling below 16 deg C.
