Hello everyone,
I have been encountering a problem lately when I try to model a radiant floor in OpenStudio.
I am currently using the OpenStudio 1.9.0 plugin for SketchUp.
I have a two story building, one thermal zone per floor, with each floor having a radiant floor heating system. I have created an internal source for each floor and added it to the respective construction set for each floor. I also added a 'low temperature radiant variable flow' to the zone equipment for each thermal zone, along with a cooling schedule and heating schedule, and linked the equipment to the thermal zones. Then I created an empty plant loop and added a boiler, setpoint manager schedule (HW Temp), and a variable speed pump.
When I run the simulation I get the following errors: * Severe * IP: IDF line~524 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOWFLOORS, Required Field=[Surface 1 Name] was blank. * Severe * IP: IDF line~524 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOWFLOORS, Required Field=[Flow Fraction for Surface 1] was blank. * Severe * IP: IDF line~2331 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOW 1FLOORS, Required Field=[Surface 1 Name] was blank. * Severe * IP: IDF line~2331 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOW 1FLOORS, Required Field=[Flow Fraction for Surface 1] was blank. * Severe * IP: IDF line~5354 Error detected in Object=PLANTEQUIPMENTOPERATIONSCHEMES, name=PLANT LOOP 1 OPERATION SCHEMES * ~~~ * Field [Control Scheme 1 Schedule Name] is required but was blank
I've looked all through OpenStudio and cannot find a way to solve any of these errors. I can solve them in E+, but I'd like to be able to solve them in OpenStudio. Do I need to write a measure to solve these in OpenStudio?
Thank you for any help! Let me know if I need to post the IDF file, I'm new to posting on Unmet Hours and am not sure if that is standard procedure or not.
