Re: [EnergyPlus_Support] Energy Modeling with the new MS Surface book Core i5 and no dGPU



Since E+ was converted to C++, I understand it's getting faster, but don't know if it still cares (as it used to) a lot about RAM size and hard drive speed.
Nonetheless, we use 2 year old desktop i5s with 8GB and solid state hard drives and they work just fine.  We always, however, run models as Design Days only until confident they're correct.  That keeps run times down.
After we stat running full weather years, we still find problems, but most are already fixed.
Hope that helps.

Im buying a new laptop and already made up my mind that its going to be the new  MS Surface Book. I need your help deciding if the low spec model that  I choose is the right one for my needs.  It has Intel icore 5 8GB RAM with no dGPU (the more expensive model has Core i7 with dGPU).  I will be using it to model residential and medium size office buildings using Designbuilder and probably open studio. How much slower do you think it could be relative to the higher spec model?


I know that a desktop is better for modeling, but that doesnâ??t suite my mobility needs,  im also not considering  laptop options other than Surface Book.  I know that I higher specs model will perform better in general, but I donâ??t want to spend the extra $400 if its not going to make a bog difference, I will appreciate your insight. thanks

â???happiness is the joy produced in us by truth. To be truly happy means coming to know how things really are, experiencing ?reality in its ultimate rootâ??¦
What matters more to oneâ??s happiness than getting more freedom and power is the end toward which we order whatever freedom and power we have. Unless we order ourselves to the truth, more freedom and more power will bring only more unhappiness, examples of which abound.
