Multiple demand drivers for ESD

[Kannan]

I was trying to include multiple drivers for estimating the future energy service demand via Dem_Alloc+Series.X (e.g. space heating is driven by floor area, number degree days). When I included two drivers in DRVR allocation table (see below), VFE add the ESD from the base year.  So, from the 2^nd period (after the base year ESD), the EDS is doubled, and then the growth is constant.  What I want is, just apply the growth rate from the two drivers.  Is there way to adapt only growth rate from the both drivers?

~DRVR_Allocation
Region	Demand	Driver	Calibration	Sensitivity
CH	SH	DegDays	Constant	Elas1
CH	SH	FloorArea	Constant	Elas1

When I included both drivers separated by coma (e.g. DegDays, FloorArea), VFE ignores!  I am missing something here, but unsure.  Has any one modelled multiple drivers?  Appreciate any little help/feedbacks.

Thanks

Kannan you can allocate only one driver to each ESD. So what you are trying to do it is not possible.

The best approach in this case is to create a new driver (e.g. DDFL) that is the combination of the DegDays and FloorArea and use this new driver to project your ESD.  This is an example with three different drivers by region: GDP, POP and GDPP. GDPP is the ration between GDP and POP. Then you can allocate the GDPP driver to any of your ESD.

Mauri, thanks for this clarification.  Oh, it is not possible !  I thought it is doable.  

Similar to what you have suggested was implemented (in our single sector model).  However, number of drivers are increasing and we have numerous ESD for industrial subsectors, so is subsectoral GDP.    So I'm  trying to find an automated alternative!

Ok, then, let me proceed with your suggestions again.

Amit may consider enabling such option for the future development

Thanks again
