13  Dividing an IE unit into sub-units

Note: The sub-units are used as the basis of abatement calculations, rather than the IE units themselves.  Each sub-unit must draw fuel or electricity from outside the IE unit, and must contribute a part of the output of the unit.  Conceptually, they are parallel systems, but they may exchange energy between themselves.
 (1) The project proponent may divide an IE unit into 2 or more subsystems that satisfy subsection (4).
 (2) If the IE unit is divided in this way, each such system is a sub-unit of the unit.
 (3) If the IE unit is not divided, the whole of the unit is taken to be a sub-unit of itself
 (4) The subsystem satisfies this section if, before and after the upgrade:
 (a) it includes an item of energy-consuming equipment; and
 (b) it has outputs that are outputs of the IE unit, and not inputs to another subsystem; and
 (c) it draws energy from electricity or fuel that is:
 (i) from outside the IE unit; and
 (ii) can be measured or accounted for separately from the electricity or fuel drawn by other subsystems; and
 (d) it uses the energy principally to provide IE services, either as outputs of the subsystem, or in order to serve equipment that is included in the subsystem.
Note: A sub-unit may consist of equipment that is not directly affected by any part of the upgrade. It must draw at least some energy from outside the IE unit to satisfy paragraph (c), so that the abatement calculations can be made. However, this energy could be supplementary to the energy provided by other sub-units, eg. recovered heat.
