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

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 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% Existing Buildings - Challenges

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 Well – profusion 15 l/s,t= 17,5 °C Heat pump110 KW 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 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
