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

[RobertWichert]

Some of you may know that I use EnergyPro for this sort of thing.  You 
can build a very simple building if you want to.  A box.  Window area.  
Internal people and lighting.  If it is multi-story you can multiply the 
floors, just like EQuest and the rest.

I suppose the most important thing is the weather file, and EnergyPro 
has many to choose from, and everywhere in California where I work.  For 
me, in California, it is the obvious choice.

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.

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.
