The main objectives of this particular thesis are: (a) To highlight the utilizability of combined retrofitting solutions. In other words, the primary objective is to compare the efficiency of different energy saving methods, when combined with each other. (b) To suggest optimal retrofitting solutions, in order to achieve maximum efficiency. The secondary objective focuses on analysing the energy savings of each retrofitting method and each effectiveness when combined, in order to propose the best outcome, while taking into account the energy savings of each method and not other factors, such as time and cost of the implementation.In this study a campus building of the Technical University of Crete is used (K1 building). The modeling software used for data collection modeling is OpenStudio. This simulation tool is used to evaluate the building’s performance and the overlapping and synergistic effects when multiple retrofitting scenarios are being applied. The Utilizability Index is employed for the analysis of these effects in buildings and is defined as the ratio of energy savings derived from applying combined solutions to a building over the sum of individual energy savings from applying the same solutions individually. The analysis on the utilizability value provides a selection criterion for retrofitting solution selection, which indicates the importance of this concept.
