ENERGY EFFICIENCY IN THE BUILDING SECTOR – AN

IMPORTANT CONDITION FOR the successful use of GEOTHERMAL

ENERGY

Numerous Advantages of Energy Efficiency

Energy Efficiency in Buildings - Status

New buildings – how low can we go?

Future of Buildings

• 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

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

NEW HEATING TECHNOLOGY

• 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

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

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

Energy modernization creates jobs

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
