ÂI suggest you run  your model, then open the .rdd file.ÂHere you will find variables for lights on the zone level.  The one I think you are looking for is "Output:Variable,*,Zone Lights Electric Energy,hourly; !- Zone Sum [J]"However there are a few others that are also interisting for thermal studies where you want to look at the source of your heat gains.ÂOutput:Variable,*,Zone Lights Convective Heating Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Convective Heating Rate,hourly; !- Zone Average [W]Output:Variable,*,Zone Lights Electric Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Electric Power,hourly; !- Zone Average [W]Output:Variable,*,Zone Lights Radiant Heating Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Radiant Heating Rate,hourly; !- Zone Average [W]Output:Variable,*,Zone Lights Return Air Heating Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Return Air Heating Rate,hourly; !- Zone Average [W]Output:Variable,*,Zone Lights Total Heating Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Total Heating Rate,hourly; !- Zone Average [W]Output:Variable,*,Zone Lights Visible Radiation Heating Energy,hourly; !- Zone Sum [J]Output:Variable,*,Zone Lights Visible Radiation Heating Rate,hourly; !- Zone Average [W]â??â??Jeremiah D.
