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

Hi Jens,
I would support Sasa's recommendation to consider DesignBuilder for the application you have suggested, adding that you can easily do both loads calculations and simulations to determine power and energy consumption from the various energy systems in the building such as HVAC, lighting and equipment. You can create the building geometry and define internal gains, HVAC (via simplified schematic drag-and-drop or menu options) etc. quickly and easily for early-stage analysis (there are many free online tutorials showing how to do this), and then develop the complexity of it as your design matures.
Regards,
Dave

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

Bentley
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)
