[TRNSYS-users] Solar Load

Patrick,
  Try NTYPE901 - its a solar balance on a given zone. An output file 
will be generated by Type56 with all the terms of the solar balance as 
described on page 6-26 of the 06-MultizoneBuilding manual. One thing to 
be careful about is that each entry in the output file is the value of a 
given energy transfer over the previous timestep. However, the values 
are only generated once per hour. If you are able to run in energy rate 
control and use a 1 hour time step, there is no problem but if you are 
running with a shorter time step, you'll only be able to see the value 
of the energy transfer over the last time step in the hour. Its a known 
problem and one that will presumably be worked out in the next version.
Kind regards,
 David
