| A lot of studies focus on IAQ in classrooms and energy retrofit of schools in order to increase the pupils’ performance and reduce energy consumption. However, there are limited number of studies that compare the calculated (as part of energy audits) and actual energy savings, discussing such a difference in order to give the recommendation for the future renovation projects. Long-term field data were collected over eight heating seasons from four schools organized into two groups characterized by different range of modernization activities. The group A includes two schools where besides the thermal modernization of building envelopes, the central heating installation was modernized and hydraulic balanced. The group B also comprises two schools where only the thermal retrofit of building envelopes took place, but the heating installation was not modernized, nor hydraulic balanced. The calculated level of energy saving was not covered in 18.1% and 20.3% in the case of schools from group A and in 47.2% and 41.1% in the case of schools from group B, respectively. The results may be of interest for the investors, engineers and policy makers who intend to minimize the difference between the planned and real energy savings as well as the payback time of modernization activities |
