Revision history [back]

I am using OpenStudio Application 1.6 to run a daylighting simulation using the radiance measure to check how much reduction in interior lighting annual kWh consumption the daylighting measure will provide. I ran the simulations using two models, one without the measure and the daylighting controls and illumination maps, and the other using the measure with the controls and maps. The resulting interior lighting annual kWh consumption is the same for both runs. The messages appearing while the simulation is running with the measure are saying "Cannot find timeseries 'Zone Lights Electric Power' for Thermal Zone 'Perimeter ...', skipping". Attached are the messages. Could this be the reason for the same interior lighting kWh in both runs? There is a similar question posted a year ago but was not answered so I hope I could get an answer to help revise my model. Thanks.
