Figure 10 illustrates the cash flow of<br />
the internal revolving fund for one<br />
example project with a payback time<br />
of 8 years and a project lifetime of<br />
15 years. The payback time depends<br />
on the policy defined on how savings<br />
will be returned to the fund. If the<br />
savings are returned to the revolving<br />
fund in full, then the payback time<br />
will be 8 years. After that time, the<br />
financial department usually claims<br />
the savings and will reduce the client’s<br />
budget accordingly. However, savings<br />
can also be returned to the revolving<br />
fund beyond the payback time, until<br />
the end of the project lifetime. In this<br />
period, savings can be split between<br />
the beneficiary and the revolving fund<br />
or the total savings can be transferred<br />
to the revolving fund.<br />
Figure 11 shows the cash flow for<br />
the client of the Internal <strong>Contracting</strong><br />
system. The client will see the energy<br />
costs decrease after the investment.<br />
Usually, savings are not only achieved<br />
for energy costs but also for operating<br />
and running costs (depicted as cost<br />
savings). The client will transfer the<br />
rest of the savings to the revolving<br />
fund. The duration of the savings<br />
transfer will depend on the agreement<br />
(or defined policy as stated above)<br />
between the revolving fund and the<br />
client. In this (somewhat ideal) case,<br />
the client will achieve the full potential<br />
of its savings after the payback time.<br />
Until Year 8, the major part of the<br />
savings will be transferred to the<br />
revolving fund and after that and<br />
until the end of the project lifetime,<br />
the client will reap the benefits of its<br />
investment.<br />
