Design Builder's Energy Plus Simulation Took 3.5 Hours
Hi Everyone,
Somewhat of a novice to this building energy modelling.. I am using design builder and enegry plus. My building is 19,000 m2 floor area, I am running a cumulative analysis for this building to demonstrate specific improvements and their reductions in energy and electrical usage.
I have ran a baseline simulation, recorded the results, then I modelled improved windows, recorded results, then I modelled improved u values for flat roofs. All capturing the previous improvements and showing a pathway to reduce X amount. But when I model 600 m2 of solar panel array split across 2 arrays, the simulation last night took 3.5 hours to run. I've optimized my RAM to run through DB, good internet.
Is this normal for this to run this long? Usually other simulations take 40 minutes (new windows/roofs). Any help is much appreciated.
