1. Check the DesignBuilder session logs https://designbuilder.co.uk/helpv7.0/#Diagnostics.htm 2. If the logs are showing: _Temporary folder: C:\Users\YourUsername\AppData\Local\Temp_ Daylighting::DoDaylightingCalcs - Command 'cnt.exe 577 | rcalc.exe -e MF:2 -f reinsrc.cal -e Rbin=recno -o "solar source sun 0 0 4 ${Dx} ${Dy} ${Dz} 0.533" >> "C:\Users\LuisS1\AppData\Local\Temp\dkl3athd.imv.Building-1.geom_sun"' failed to run: reinsrc.cal: cannot open Stack trace: 3. Then you may have installed the standalone Radiance at some point. Solution: Delete the user and system environment variable RAYPATH and try again. At Control Panel > System > Advanced system settings > Advanced (tab) > Environment Variables > Under "System variables" and “User variable”, find RAYPATH and delete it. Also, delete all Daysim and Radiance references on the Path variable at both user and system level. Then start a new DB session and try Annual Daylighting. You may also have other applications that are using Radiance then a workaround is to copy reinsrc.cal file from the DesignBuilder installation folder of Radiance ( C:\Program Files (x86)\DesignBuilder\Radiance-5.2\lib) to all other locations where Radiance is installed. 20.09.2021 | |
