Bratislava, Slovakia

A project within Eu-GUGLE.


Bratislava, the capital of Slovakia, has a population of about 460,000 and is the country’s largest city, covering a total area of 367.58 square kilometers. Located in the southwestern Slovakia, Bratislava occupies both banks of the Danube River and the left bank of the Morava River. The city is the only national capital that borders two independent countries – Austria and Hungary and it has a long and proud history that dates back to pre-Roman times.

The district and the building stock
In Bratislava, high demand of affordable housing for low costs resulted in a very low building quality. High-rise buildings in many areas are poorly insulated and aren’t airtight anymore. The cost of replacing of these buildings in a short term would be well beyond the means, because flats are owner occupied.


Technical and non technical measures
- Energy consumption of buildings:
- Insulation of peripheral constructions
- Roof insulation,
- Insulation of windows,
- Joint sealing of peripheral panels

Heating systems in buildings:
- Increase the level of weather-compensated regulation,
- Installation of thermostatic valves
- Adjustment of systems.

Hot water preparation:
- Increase of the insulation of all parts of the system
- Measurement of hot water usage,
- Efficient decentralization of domestic hot water.

Impact and Socio-economic impact for the area
Energy saving compared to national regulation should reach up to 43 %. The estimate durability of the house will be increased as well as the living comfort.
