Directive (EU) 2018/2002 of the European Parliament and of the Council amending Directive 2012/27/EU on energy efficiency sets a target of 32.5 % energy efficiency to be achieved by 2030, with a possible upward revision in 2023. The directive also stipulates that the obligation to achieve annual energy savings must continue to be met after 2020. In addition, a revised directive on the energy performance of buildings was adopted in May 2018. It includes measures to speed up the renovation of buildings and the transition to more energy-efficient systems, as well as to improve the energy efficiency of new buildings, thus using smart energy management systems (Amanatidis, G, 2020). Buildings consume the most energy and have the greatest energy saving potential. They are therefore crucial to achieving the European Union’s energy saving targets. The EU allocated around 14 billion EUR to improve the energy efficiency of buildings in the period of 2014–2020, of which 4.6 billion EUR was intended for residential buildings. In addition, the Member States have earmarked 5.4 billion EUR of public co-financing for the improvement of all types of buildings, of which around 2 billion EUR is allocated to residential buildings. Multi-apartment residential buildings in Latvia are in a technically unsatisfactory condition. In Latvia, the service life of multi-apartment residential buildings has been artificially extended. In addition, there is also the problem of reduced construction quality. Housing problems affect all layers of society, but they are most acute for low- and middle-income people. The aim of the research is to study, using the co-financing of the European Union Structural Funds, the activities performed during the renovation process of multi- apartment residential buildings in Latvia and to identify the shortcomings.
