Enable Economizer Control Ruby measure There is currently not a functioning air side economizer enabled in the building. Air side economizers use cold outside air to either assist the mechanical cooling system, or if the air is cold enough, provide all of the cooling for a facility. In order for an air side economizer to...

GLHEProGFunctionImport Ruby measure After running GLHEPro to size the GLHE and export the G Function .idf file, use this measure to import these GLHE inputs back into the model. In order to export the loads necessary to size the bore field, see the Reporting measure called 'GLHEPro Export Loads for Ground Heat Exchanger Sizing.'

Add Variable Speed RTU Control Logic Ruby measure This measure adds control logic for a variable-speed RTU to the model. The control logic is responsible for staging the fan in response to the amount of heating/cooling required. It is meant to be paired specifically with the Create Variable Speed RTU OpenStudio measure. Users enter the fan flow...

Create Variable Speed RTU Ruby measure This measure examines the existing HVAC system(s) present in the current OpenStudio model. If a constant-speed system is found, the user can opt to have the measure replace that system with a variable-speed RTU. 'Variable speed' in this case means that the compressor will be operated using...
