More c3s implies more CaO.
Theoretically the cost of this is mainly the heat of decarbonation.
Roughly, this will be twice higher because of the various heat losses.
Any kiln balance tool can be used to calculate that.
You can find all the data on the heat of reactions in any textbook of cement kilns.
Have a look for the VT10 notes from VDZ, like there: http://www.scribd.com/doc/50011494/kiln-vt10-english  , specially page 63.
