I am developing a simple interface for EP and I would like to include some sensitivity analysis options in my interface. I want to allow the user just by clicking a button, to effectuate a series of simulations for the same idf file but including all steps of a predefined ranged. For example, if the user click on the sensitivity analysis button that is associated with insulation thickness the RunBatch will run 5 simulations using the same IDF input file but changing the insulation thickness 5 times (2,5,7,10,12 cm). How can I do that?
I succeed to modify single parameters in the idf file using my interface and then running the simulation through a RUNEP.BAT. But how can I run a series of parallel simulations (steps) representing the range of one selected parameters? how would the outcome look like? Will EP generate every simulation a new output file for every step?
Thanks in advance,

Subject: [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.
