As usual, this is really simple after you know the answer. The constants are from kBtu/kWh = 0.2931 and kBtu/therm = 0.01, (I kept trying to figure out how [J source/J site] fit in from the FuelFactors object) which makes the TDV factors lose their energy units, then multiplied by output variables [J] from EnergyPlus, so the resulting unit is J TDV. At least, I'm pretty confident the output unit is J TDV, not kBtu TDV.
I'll wait for some confirmation before accepting this answer though.
