Configuring ventilation and lighting

You can access and edit the data on the property tabs defining the configuration for IT load, infiltration, ventilation, and lighting by right-clicking an energy system and selecting Properties or by clicking the icons at the bottom of the Energy System pane. The configuration options vary based on the type of subsystem.

1. Right-click the energy system and select > Properties> Ventilation.
2. Define the general settings for the energy system's ventilation.
   1. Select if the ventilation is on the critical or primary power path, or if there is no ventilation to be included in this energy system.
   2. Select if the ventilation data is measured (live) or computed (without power meters).
3. Define the configuration of the energy system's ventilation.
   1. In Actual kW Nameplate, type the total nameplate value of the ventilation.
   2. In Usable fraction of nameplate w/o derating, type a number between 0 and 100, indicating the usable fraction of power that can be used within the devices in this subsystem without derating.
   3. In Redundancy, type the redundancy of the subsystem.
   4. In Redundancy +1 kW Increment, type the loss in kilowatt caused by internal redundancy. (Only needed if the redundancy option includes +1)
   5. In Derate Capacity fraction, type a number between 0 and 1, indicating the usable fraction of the ventilation equipment nameplate value.
   6. In Typical PU, type the power usage (PU) of the ventilation in power units relative to the total power usage.
4. Define the loss configuration of the energy system's ventilation.
   1. In Fixed loss, type a number between 0 and 100, indicating the fraction of power that is the fixed loss of the ventilation.
   2. In Proportional loss, type a number between 0 and 100, indicating the fraction of power that is lost proportional to the load of the data center.
   3. In Square Law loss, type a number between 0 and 100, indicating the fraction of power that is lost proportional to the square of the load of the data center.
   4. In Dry bulb fixed loss, type a number between 0 and 100, indicating the fraction of power lost per degree Celsius dry bulb.
5. Use the Script tab for writing scripts that retrieve measurements.
6. Click Lighting and repeat the above steps for configuring the energy system's lighting settings.
