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 />
