[Bldg-sim] Energy needs at an early design stage

[Nick Caton]

Another option to consider, if you are already familiar with Sketchup, is the free IES-VE Ware plugin.  Similar in function to what's been described for AECOSim, but from my experience I'll caution you WILL want to plan on time to create the model from scratch.  Every effort I've made to re-utilize a model constructed by others for other purposes (aesthetic renders and such) has led me to scrapping the effort.

Hello,

If by energy need you are referring to energy consumption (Wh), I would suggest to go with RETScreen. 
If you are referring to cooling/heating loads (W) try Design Builder. 
Downside is that you can't get block load for entire building. (Maybe this issue is resolved with newer version).
HAP can also do the job.
Cheers,Sasa Pantic

 Systems’ AECOsim Energy Simulator has a conceptual  mode – about 10 inputs (mostly from drop-down boxes),  draw the outline of the footprint, select from
  a dozen preconfigured HVAC system (drag-and-drop  components, all 90.1 required baseline and budget systems),  and simulate.  And it uses EnergyPlus.  Once your  conceptual model is ready, you can modify all the default  parameters.

 Dear all,
  
 Does anyone of you know a software
 program which I can use to calculate the energy needs of a  building (installed power) at an early stage (design).
  With the usual programs like EnergyPlus or Trnsys you need  to insert a lot of parameters to get the information,  parameters which  just aren’t allways available  in the design stage.
 
 
 The calculations don’t have to be very precise,  I’m looking for a tool which can give an acceptable  result, so we can give our customer an idea of how much  power is needed for a certain building. 
   
 Greatfully,
 Jens Wagemakers (The
 Netherlands)
