Split-wired receptacles

In order to comply with recent energy code requirements for plug-load control, we are entertaining the idea of using split-wired receptacles in office spaces, so that we can control (automatically turn ON or OFF) the top portion of a duplex receptacle, & leave the bottom half of the receptacle "hot". Both top & bottom halves of the receptacle will be served from the same branch circuit, they're simply going to be divided into controlled, & not controlled halves.

Is this considered a multi-wire branch circuit?
 
No.

Branch Circuit, Multiwire. A branch circuit that consists
of two or more ungrounded conductors that have a voltage
between them, and a grounded conductor that has equal
voltage between it and each ungrounded conductor of the
circuit and that is connected to the neutral or grounded
conductor of the system.

How could it be a MWBC if there is only one branch circuit serving the receptacle?
 
If you had the bottom half controlled from one circuit and the top half from another circuit while sharing the neutral then it would be a MWBC
 
As the others said, no your setup is not considered a multi-circuit, but it is consider a switched outlet.
