Evaluation of energy efficiency measures applied in public buildings (schools & hospitals) in Serbia

The Serbian Energy Efficiency Project 1 (SEEP1 - Design and Supervision Support for Implementation of the Energy Efficiency Improvements in Public Buildings in Serbia), funded by a credit from The World Bank, has involved the energy efficient refurbishment of 28 public buildings in Serbia (12 hospitals and 16 schools). The major goal of the project has been implementation of the energy efficiency improvements in public buildings in Serbia and the verification of the energy and cost savings as well as CO2 emission reductions achieved through implementation of the energy efficiency measures. Significant energy consumption savings have been achieved for all refurbished buildings with annual savings in the range of 15% to 63% and an average of 40% over entire project. Associated annual CO2 emission reductions vary between 15% to 64% with an average of 42%. The average specific space heating annual energy consumption for the hospitals monitored was ~339 kWh/m2 and has been reduced down to ~205 kWh/m2 after refurbishment. The average specific space heating annual energy consumption for the schools monitored was ~243 kWh/m2 and has been reduced down to ~144 kWh/m2 after refurbishment. The simple payback period (SPP) on investment across all buildings was found to be about 7.5 years. For hospitals, due to their 24/7 operation, the average SPP is 5.3 years and for schools is 12.8 years.
