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”
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%
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
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
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
Examples of measures taken – additional isolation and new windows – commercial building BE
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
Way to the use of geothermal energy • Adequacy-study • Project of detailed hydrogeological exploration....... • Exploration rigths • Elaboration on reserves • Exploitation rights
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
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
