Setting Up Components:DOAS on Level 1 Import the system as a measure from theBCL library. Edit the System Loop. Add componentsspecific to your design on the supply side:fan, ERV, etc. Assign zones to the system (demand side) Size the air loop Assign set point managers for appropriatecontrols.Image: UC Riverside
Setting Up Components:DOAS with VRF Systems VRF comes with the measure NREL provides sample LG VRFunits (air cooled) which can beimported as a measure Drop the thermal zones Size both the condensing andindoor units Our project had a water cooledVRF system, so we had to createa separate EnergyPlus measure.Image: UC RiversideCondensing Unit

OpenStudio Limitations1. Water Cooled VRF Systems need to be modeled through an EnergyPlus measure2. Dynamic shading and dynamic glass can be modeled only through anEnergyPlus measure.3. HVAC controls need to be prioritized manually in the idf file or through ameasure, for example:Image: UC Riverside VRF Zone SAT does not follow the setpoint manager as it references a zoneto control off instead of SAT setpoint.4. Geo-thermal heat exchanger was sized based on the loop operatingtemperatures. District Heating and Cooling objects were used to model the heatexchanger. Another option is to get the G inputs from GLHEPro sizing software.SOURCE
