The energy consumption of residential buildings in Ukraine is 32% [1] of the total final energy consumption and 11% of CO2 emissions [2], which makes them the largest energy consumer in the country.
Currently, about 66% of residential buildings in Ukraine are older than 50 years [3], and almost 80% of the residential building stock is inefficient [4] in terms of energy consumption.
The total area of residential buildings stock in Ukraine is about 968.4 million sq.m., 60% of these areas are located in urban settlements [5].
At the same time, less than 0.1% of the housing stock is modernized annually in the country [6].
Residential buildings have the highest potential for energy saving – 49.6% of the total energy saving potential in Ukraine.
According to different estimates, investment requirements for the complete thermal modernization of the housing stock in Ukraine amount to approx. EUR 45 billion.
The main problems in improving the energy efficiency of residential buildings in Ukraine are:
