Ies ve parametric tool guide amp study

IES VE PA R A M E T R I C TOOL Guide Study CTHE TOOL The parametric batch processor PBP in IES VE allows simultaneous simulations of di ?erent models the same model with varying parameters set within the tool The model used is a - oor o ?ce building located in London with some vegetation north-east Figure study model in IES VE objectives Run parallel simulations for di ?erent orientation WWR and overhang con ?gurations CWO R K F L OW De ?ne model geometry data De ?ne variant data choices Setup and add to queue ApcheSIM Repeat for each model Run PBP Select apr ?les to run Select variables to change Set other options scale range ? Run parallel simulations CSTEP - SETUP De ?ning model in the VE using Building Template Manager as you typically would To set up the variable simulations later de ?ne also other options eg overhang added onto external windows CSTEP ?? SIM SETUP After running SunCast for each model orientations and WWR was set up in di ?erent ?les the Apache Simulation can be set up specifying name simulation and output options as usual Instead of simulating the model is added to queue which creates a new ?le of apr format in the VE folder of the model After setting up all models or just one the parametric batch processor can be launched from the navigator tab CHere all the simulation models can be added and the variables and number of simulations for each model can be determined The apr ?les for each model can be found in the VE model folder parametric batch modelname apr Under ??variable ? the parameter you wish to change can be selected In this case we have variable overhang lengths so di ?erent external window con ?gurations were selected It is possible to modify the following variables CONSTRUCTIONS External Floor External Wall Internal Wall Internal Floor Ceiling Roof External Window External Roo ight ENERGY Heating Setpoint C Cooling Setpoint C In ?ltration Rate Ac hr Aux Air Rate Ac hr Nat Vent Air Rate Ac hr Photovoltaics Area m Wind Turbine Power kW CWhile constructions can be varied depending on con ?gurations created previously in Building Template manager the energy related variables can be speci ?ed with minimum maximum and iteration step size CSTEP ?? run result After the setup the simulations can be run at once The results can be found in VistaPro as results ?les TIME needed for simulations in PBP min TIME needed for conventional sim min Cconclusion In total the parallel simulations do not save time as the total time is the same Also the VE cannot be used while simulations are running However it does make the process simpler as the setup is simpler for the selected variables and suncast apache do not have to be run separately In total this will still save time and prevent mistakes in the process C
