[EnergyPlus_Support] Re: How to generically model hourly residential electricity use

Electricity demand is fairly unpredictable on the single house level. Then again, unless you're off-grid or have time-of-use rates, exact timing might not be too critical. Having done a literature review in this area, I can say that one of the best sources is:

http://nparc.cisti-icist.nrc-cnrc.gc.ca/npsi/ctrl?action=rtdoc&an=5757522

It's based on Canadian data, but I doubt it's that different from the US. Also, you could probably scale the profile if you have some aggregate US household data to compare to.

I was thinking the basic inputs would be ambient temp, altitude, square footage, occupancy (1,2 etc.) and maybe wind speed. I'm not looking for something that is exact but I was hoping there are some generic equations that might help me with this problem. Advice on how to approach the problem would also be appreciated. If there are papers that address this issue please recommend them. If anyone knows of a database that contains real load profiles this would also be a big help. Any help is appreciated.
