| VAV Terminal Unoccupied Setback | Ruby measure | For a selected thermal zone, applies unoccupied setbacks: (1) derives the
occupancy schedule via Space → Space Type → People, creates a modified
airflow turndown schedule, and assigns it to the zone's VAV terminal; (2)
finds the zone thermostat DualSetpoint, clones the heating and... Repo: Ski90Moo/OpenStudio_Measures_HEPLLC |

| Set IdealAirLoads to Control Humidity | Ruby measure | Configures humidity controls on the HVACTemplate:Zone:IdealLoadsAirSystem
for a specified thermal zone. Reads the zone's ZoneControl:Humidistat,
computes daily average setpoints from its humidifying and dehumidifying
schedules, and applies them along with the user-selected control... Repo: Ski90Moo/OpenStudio_Measures_HEPLLC |

| Fan Assist Night Ventilation | Ruby measure | This measure is meant to roughly model the impact of fan assisted night ventilation. The user needs to have a ventilation schedule in the model, operable windows where natural ventilation is desired, and air walls or interior operable windows in walls and floors to define the path of air through...

| Enable Demand Controlled Ventilation | Ruby measure | The facility currently does not have a demand controlled ventilation system or CO2 sensors in the air delivery system. Outside air is introduced and conditioned at a fixed rate based on the maximum design. Since the building occupancy fluctuates and is often less than the maximum design...

| 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... Repo: NatLabRockies/openstudio-ee-gem |

| 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.' Repo: NatLabRockies/openstudio-ee-gem |

| 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... Repo: NatLabRockies/openstudio-ee-gem |

| 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... Repo: NatLabRockies/openstudio-ee-gem |
