3.1 Assess the costs of the work
There are two methods:
Perform internal costing: this method involves calculating the cost of the work using, for example, simulators available online.
rely on the recommendations of the energy auditor: this more reliable method also saves time, as the renovation costs per item are already included in the audit report.
Regardless of the method chosen, sources of funding must be found to carry out the work.
