The rehabilitation scenarios, as defined in "Phase 3: Improvement programs",
will be the subject of a detailed financial analysis.
This will be produced using the "global cost" method, and will assume 4:
- Energy price trends according to the average annual growth rate (AAGR).
- Payback periods of 10, 20 and 30 years to calculate the return on investment (ROI)
. These estimates will then be compared with a baseline scenario, to
highlight the savings generated on operating and maintenance costs,
for each of the defined periods.
The analysis will highlight, for each scenario : - The estimated cost of the work (estimated amount per item and overall).
- Operating costs for each use (conventional and
specific electricity uses). - The cost of maintaining the installations (P2), identifying the person to whom
this responsibility is assigned (tenant, owner, manager, operator, etc.) and the consequences if this
maintenance is not carried out. - The estimated cost of renewing heavy equipment over the period used for the analysis
. - Estimated payback times for all investment items. The corresponding
investments and their payback times will be specified on the basis of a
preliminary budget estimate +/- 20%. The source of information used for the
reference costs will be mentioned, to enable the project owner to
update the proposed costing at a later date. Complex interventions will be the subject
of more detailed studies, if necessary. However, to facilitate the decision-making process, the
service provider will mention in its costing the financial support methods or schemes
applicable depending on the client's situation: energy saving certificates, tax credits
, national or local subsidies, etc. The energy audit may, where appropriate, be
followed by a support phase designed to help the beneficiary implement
the recommendations made. This phase lasts a few days and is carried out by
after the final audit report has been submitted. It should not be confused with a
project management assignment. The service provider carrying out the support service may
also be different from the one who carried out the audit.
