Hi everyone,
I have been trying to use PAT to calibrate a building model to measured data. The building model was developed using project specifications, i have measured data for almost a full year, with 10 min granularity (timestep) for rooms temperature and HVAC energy consumption. I also have a AMY weather file for that specific location.
I am currently running PAT in Algorithmic mode using OpenStudio-server on AWS, with a node type "t2.large" and max of 4 nodes.
My problem is the run time per each simulation. Running the model locally using EnergyPlus takes round 30s while in PAT is taking almost 3 minutes.
I have done some testing and believe that the problem is the reporting measure "Time Series Objective Function" that i am using to calculate calibration metrics (CVRMSE). This measure is being used per each room with temperature readings (8 rooms) plus for total HVAC energy consumption.
I would like to know if there is a way to improve simulation time and also if it is possible to run simulations in parallel.
Thanks!
