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 CO₂ 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 CO₂ 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.

能源效率计划的事后评估：捷克绿色投资计划的案例研究

近年来，大量资金可用于提高建筑物的能效。但是，对方案的实际影响进行仔细评估仍然不够。本文提供了对能源效率计划的预期结果与实际结果之间关系的见解。它以中欧最重要的能源效率和可再生能源计划之一“绿色节约计划”为例。该计划的124个项目总共检查了206项措施。检查分析表明，预期的，已验证的CO ₂之间存在显着差异减排量和事后实际削减量（平均减少25％）。原因部分是有条不紊的，但大多数可以归因于相应建筑物中居住者的行为因素。因此，结果清楚地表明，有必要解决计算的（预期的）节能量（和相关的CO ₂排放量减少）与受建筑物用户高度影响的实际节省量之间的关系。除其他事项外，应进行事后评估，以更准确地了解成员国的能源效率改善义务。此外，此类评估还为进一步优化未来的能效支持计划提供了必要的投入。
