Cold climate EU10 countries

Headline facts and figures

Broadly representative of Estonia, Latvia, Lithuania and Poland
6.1 million dwellings
125,000 buildings (theoretical)
41% of dwellings in the region
Energy-saving potential in stock: 34%, equivalent to 4.4% of region’s final energy demand or 9.3 MtCO2 emissions

Predominant construction and heating features

Prefabricated concrete panel walls, flat concrete roof and ground floor above an unheated basement, secondary-glazed, plastic frame windows
District heating, allowing installation of TRVs and balancing valves

Issues

Highest dwelling proportion, second highest energy saving potential and CO2 reductions.
Fairly homogeneous high-rise stock.
Low cost-effectiveness of investment due to low energy prices.
