Re: [EnergyPlus_Support] Lift truck energy expressed as an internal load



Dru,
That's a valuable insight (impact of charging the lift trucks on demand cost).  The report itself is very interesting; I skimmed it and will read it more thoughtfully a bit later.
I will talk to Mike Deru or another of the authors, bit I'm still hoping that others also contribute their knowledge.

Jim,

When NREL was working on a low-energy building in Colorado, they found they needed to schedule the charger on the forklift -- or it set the peak demand for the building.  Here's a link to the report:  http://www.nrel.gov/docs/fy05osti/34930.pdf  I'm sure the authors could provide more insights.

Dear Forum,
For the first time, it occurs to me that a lift truck used to transport materials inside of a warehouse constitutes an internal load; the work that it does becomes heat inside the warehouse.  This is true for propane and electrical lift trucks; all energy becomes heat eventually.
While it is probably a small load, I am interested in determining its magnitude.  Have any of you attempted to quantify it?  or have reference materials which do so?
Thanks in advance.
