I have been trying to use the "Set Residential Solar Water Heating" Measure available on BCL. The model runs and does not error our on the Measure. However, I look at the in.idf file that is generated and it appears to correctly create the storage tank for the solar thermal system, but there are not source side nodes defined for the tank or the solar collector objects. I am very familiar with E+, but I am not familiar with Ruby or Measure development and cannot debug the Measure code myself. Thanks, Josh
