Abstract
Estimated cost of different building technology solutions to carry out a thermal rehabilitation in a residential block of flats is determined in this paper. In recent years the thermal rehabilitation improvements has been the result of the building repairs on facades and/or roofs due to pathologic process. Taking advantages of this maintenance works, the possibility of intervening on thermal materials and systems on the building envelope was presented. In this case the investment was the extra-costs that supposed the insulating materials only (differential cost). Nowadays the rehabilitation sector is growing up with the exclusive aimed to restore buildings considering energy savings. It is necessary to quantify the cost of this interventions motivated by the new regulation framework, to reduce CO2 emissions and to certify existing buildings. The real cost of specific rehabilitation solutions and energy payback period is determined. The estimated annual savings of energy consumption is considered. The results may be useful for developing a framework that clarifies in which cases a rehabilitation of this type is worth.
