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

[Sasa Pantic]

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)
