Energy analyses of 16 public buildings and recommendations for development possibilities György MÁRTON 27.03.2015.
METHODOLOGY OF ENERGY ANALYSIS Tasks to be elaborated: 1. Compiling the set of operative regulations of the Hungarian side 2. Defining questions and scope of required data for the joint questionnaire of building selections 3. Surveying public buildings of involved 9 municipalities to select 16 buildings for energy performance analyses 4. Working on joint questionnaire of energy performance analyses 5. Analysing 16 selected buildings' energy performance in details 6. Expert taking part in 16 site visits to make on site measurements and checks about insulation, building engineering, location 7. Preparing 16 project fiches to describe the necessary investments and match them with potential funding sources

General information about the building Existing condition − Boundary structures − Heat production system − Heating system Energy analysis Proposed energy efficiency measures, estimated costs − Proposed refurbishments − Energy performance of the building after the proposed refurbishments − Estimated costs of the refurbishment Financial analysis − Estimate savings (GJ/yr, kWh/yr, tCO2/yr, HUF/yr) − Payback time (without and with EU funding) − Net present value calculation (without and with EU funding) Conclusions and recommendations
PROJECT FICHES Main findings • • • • • •
Average size of buildings: 1337 m2, 5115 m3. High heat transfer coefficients at outside walls, windows, doors, roofs, slabs, floors Gas heating with outdated thermal technique and of building engineering systems Complex refurbishment is needed at most of public buildings Present E performance levels: D – G Achievable E performance levels: B – A+
Averages of 16 public buildings: • Total investment cost: 76.4 million HUF (254.7 thousand EUR) • Estimated saving of total energy cost: 4,36 million HUF (14,55 thousand EUR) • Payback time - IRR: 19.8 yrs – 4.3% • Payback time – IRR (with 85% EU funding): 3.0 yrs – 60.9%
Investments are generally proposed to be implemented with EU funding.
