The methodology described in the previous section was applied to four buildings located in three different real test sites for a period of one year (2019). The test sites were an office building at the University of Navarre in Pamplona (Spain), a public school in Gedved (Denmark), and two buildings in the Lavrion Technological and Cultural Park (LTCP) in Lavrion, Greece: H2SusBuild and an administrative building. As shown in Figure 1, three different analyses were performed in the study: weather dataset comparison, energy comparison, and indoor temperature comparison. The following three subsections develop the three analyses.
