Error invalid model for this network
When running ASHRAE System Sizing loads calculation why does error invalid model for this network appear?
When running ASHRAE System and Sizing loads for ASHRAE 90.1 PRM Proposed model this error can occur if the Proposed.asp has been generated from a Baseline.asp.
Baseline HVAC systems have special properties to make them perform as a baseline HVAC system for ASHRAE 90.1 such as fan adjustment and are specifically linked to the baseline model (spaces or HVAC zones) so can not be used for analysis with any other model in VE (Real or Proposed).
This error may appear if you try to run an ASHRAE System Sizing calculation form Apache view using Real building and Baseline.asp or if the Baseline.asp was copied and renamed as Proposed.asp then linked in Proposed system autosizing calculations in 90.1 Navigator.
