[EnergyPlus_Support] How to generically model hourly residential electricity use


I'm working on a photovoltaic performance simulation program. The user specifies the size and orientation of the system and selects a US zip code. From there the program will load the appropriate weather file and run a basic simulation. 

The program is crude but I'm getting reasonable numbers. To develop the program further I'm looking for a basic algorithm that tells me the hourly electricity demand of a residential home. 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.
