Is the kitchen greater than 20,000 sf? If so you can use exception a) in combination with exception d) so that the proposed would be all electric with gas heat for Kitchen MAU and baseline would be system 8 and system 4 for everything except the kitchen which would be system 7.
If the kitchen is less than 20,000 sf, then it gets tricky. It may depend on the LEED reviewer you get and their interpretation, but I could argue based on the note from Table G3.1.1A, indicated below, that the predominant condition is System Type 8 and that exception b) is used to include System Type 4 where appropriate and exception d) is used for including System Type 7 in kitchens since the building isn't technically all-electric (note that exception d states to use electric resistance heating for all-electric buildings).
Where attributes make a building eligible for more than one baseline system type, use the predominant condition to determine the system type for the entire building except as noted in Exception a to Section G3.1.1.
