2015-03-24 20:41:35 -0500	commented question	Using a negative temperature in design supply temperature? The above worked, but is there a good way of going from that updated IDF file back into Open Studio? I tried importing it but all of the schedules and construction sets disappeared, and the only foreseeable thing to do would be to go back and manually add all of the missing schedules. Any other/better ideas?

2015-03-19 11:29:57 -0500	asked a question	Using a negative temperature in design supply temperature? We are trying to model a refrigerated/freezer warehouse in OpenStudio/EnergyPlus. We are using the ideal load scenario (Thermal zones section of OpenStudio). When running our model, we get a fatal error that results from the supply air temperature being set below freezing. The error file is listed below. Has anyone encountered this problem before? Are you aware if we can input the supply temperature as below freezing? * Warning * IP: Note -- Some missing fields have been filled with defaults. See the audit output file for details. * Severe * Sizing:Zone="FREEZER", invalid data. * ~~~ * ... incorrect Zone Cooling Design Supply Air Temperature=[-5.56], value should not be negative. * Severe * Sizing:Zone="FREEZER", invalid data. * ~~~ * ... incorrect Zone Heating Design Supply Air Temperature=[-7.78], value should not be negative. * Fatal * Sizing:Zone: Errors found in getting input.
