A significant amount of financing has been available for improvements in energy efficiency in buildings in recent years. However, careful evaluation of the real impacts of the programs is still inadequate. The paper provides an insight into the relationship between the expected outcomes and the actual results of an energy efficiency program. It does so on a case example of one of the most significant energy efficiency and renewable energy sources programs in Central Europe, the Green Savings Programme. In total, 206 measures were inspected in 124 projects of the program. The analysis of the inspections showed that there is a significant difference between the expected, verified CO 2 emission reduction and ex post, real attained reduction (25% on average). The reasons are partly methodical, but most can be attributed to the behavioral factors of occupants in the respective buildings. The results therefore clearly show the need to tackle the relationship between the calculated (expected) energy savings (and related CO 2 emission reduction) and the real savings which are highly influenced by building users. Ex post evaluations should be done, among other things, to provide a more accurate picture regarding the member states’ energy efficiency improvement obligations. Furthermore, such evaluation also provides an essential input for further optimisation of the future energy efficiency support programs.
