  1. ENERGY EFFICIENCY IN THE BUILDING SECTOR – AN IMPORTANT CONDITION FOR the successful use of GEOTHERMAL ENERGY Geothermal Energy in SerbiaBelgrade, September 2012 Petar Vasiljević, dipl.mach.eng JKP ”Beogradske elektrane”

  2. Numerous Advantages of Energy Efficiency

  3. Energy Efficiency in Buildings - Status

  4. New buildings – how low can we go?

  5. Future of Buildings

  6. Existing Buildings - Challenges • Sector with the greatest potential in reducing CO2 • By the year 2050 greenhouse emissions shoud be reduced by 85% compared to the year 2000 in order to limit the increase of global temperature up to 2°C • The level of Energy Efficiency – increases in the course of renovations should be from the current 20% to 85%

  7. Current Situation in Belgrade (Serbia) • The Electricity Works of Belgrade are heating 300.000 apartments in Belgrade (50% of all the apartments within the city area) – 21.000.000m2 • All the heating plants in Serbia are heating around 700.000 apartments (25% of all the apartments in Serbia) – 45.000.000 m2 • Entire heating capacity for consumers in Belgrade – 3.000 MW (in Serbia 7.000 MW) • Average specific heating energy consumption: • In Belgrade 120-160 Kwh/m2 /year • In Serbia 130-200 Kwh/m2 /year • Yearly energy consumption in Belgrade 300.000 toe of heating oil, in Serbia 750.000 toe of heating oil • Yearly expenditures for energy sources in Belgrade - 140.000.000 Euro • Yearly expenditures for energy sources in Serbia - 340.000.000 Euro

  8. How to use very little energy in existing buildings - High isolation standards for all parts of the building - Efficient windows keep the heat inside - Efficient heating, ventilation - Entire approach - Efficient products - Use of renewable energy sources

  9. How to use very little energy in existing buildings – regulatory framework • From September 30th the • Rulebook on energy efficiency • in buildings applies • GIZ helped with the creation • of the rulebook • In the following 2 months GIZ • organizes the creation of 150 • energy passports in 30 cities in • Serbia

  10. Examples of measures taken – additional isolation and new windows – commercial building BE

  11. NEW HEATING TECHNOLOGY

  12. NEW HEATING TECHNOLOGY • Well – profusion 15 l/s ,t= 17,5 °C • Heat pump110KW • Energy consumption before the reconstrucion 180 Kwh/m2 per year and afterwards 80 Kwh/m2 per year. • Heating and cooling of the object • Heating system throug fancoil-devices

  13. Way to the use of geothermal energy • Adequacy-study • Project of detailed hydrogeological exploration....... • Exploration rigths • Elaboration on reserves • Exploitation rights

  14. Example – commercial space in Konjarnik

  15. Example – commercial space in Konjarnik • New object 380 m2 • Well 1,5 l/s , t =18,5 °C • Heating and coolings system – through panels in the wall • Heat pump 28 KW

  16. Energy modernization creates jobs

  17. Political support is needed Long-term plan for significantly increased stringency with energy requests – use of EPBD 2 • Building with very little energy consumption should be the standard for new buildings • Stimulation packages for modernizations – energetic reconstrucion of existing buildings. • Modernization always at the level of energy efficiency • Public buildings should be examples of energy efficient buildings • Replacing fossil fuels with renewable energy
