When comparing the energy savings of an induction system with other systems, what items, in terms of energy usage, are not subject to the energy savings?
 The chiller, cooling tower and the associated chilled and condenser water pumps. To these must be added the mechanical services equipment such as the various exhaust fans, sump pumps, lift machine room systems and other building plant. The hours of operation are the same, as will be the energy cost, c/kWh.
 
When comparing the energy savings of an induction system with other systems, what items, in terms of energy usage, are subject to the energy savings?
 The power used by the fans is the main difference, with the induction system primary air fan handling much less air, and therefore requiring less energy. If the system had a return air fan, the savings are improved, as this fan will also be smaller. As 3.1, the hours of operation are the same, as will be the energy cost, c/kWh.
