This feature is not implemented in 1.0.0.023, which you are probably 
using.  It will be implemented and working in the next release 1.0.1<xxx> 
which is scheduled to be released in early January 2002.

Several of the example files show this, for example the TermReheat file:
  Surface:HeatTransfer,Zn001:Wall003,  !- Base Surface Name
   Wall,PARTITION06,  !- Class and Construction Name
   RESISTIVE ZONE,  !- Zone
   OtherZone,Zn003:Wall004,  !- Exterior Conditions and Target (if applicable)

At present you will have to use your own knowledge to specify the other 
surface in the other zone.  It is expected that more complex interfaces 
which are presumably under development will allow for automatic detection 
of these surfaces.

The IDF Editor, I believe, will allow you to pick from list of previously 
named surfaces but, of course, you will still have to know which one is the 
surface in the other zone.  If you have not put in the surfaces for that 
zone yet, you may need to enter all your surfaces first and then come back 
to pick the proper "other surface" surface names.

Each zone can have a floor.  A floor is just a surface (heat transfer) in a 
zone.  Again, you might look at some of the example files that are 
included.  For ease of reading, most of these will be labeled as "surface 
class" floor.

You will need to specify a report variable as listed in the report variable 
dictionary, for example:
Zone,Meter,Electricity:Facility [J]
HVAC,Sum,Zone/Sys Sensible Cooling Energy[J]

Then in your "Report Variable" input, you would select the appropriate 
attributes:

Report Variable,*,Electricity:Facility,hourly;

Would give you the facility electricity for all components that use 
electricity (and have so registered on the meter outputs) on an hourly basis.
