Climate change is one of the greatest challenges that the world is facing nowadays, and the concept of circular economy has a potential to be a part of the solution to this threatening global challenge. In the energy sector circular economy focuses on development of renewable energy sources and implementation of energy efficiency measures in residential and non-residential buildings. Non-residential buildings form the biggest part of the total Latvian housing stock – 73% according to the number of buildings and 56% according to their area. According to data provided by the State Land Service, the aggregate depreciation of non-residential buildings is 41%, and their energy performance level is low. Most of the heated non-residential buildings are related to the public and commercial sector. The final energy consumption of this sector on average is 25 PJ a year, of which about 60% (15 PJ) is used for heating. During the 2014-2020 programming period for EU funds, following support measures were introduced in the field of improvement of the energy efficiency of non-residential buildings in Latvia: measure 4.2.1.2 “Promotion of energy efficiency in public buildings” and specific support objective 4.2.2 “Promotion of an increase in energy efficiency in local authority buildings and the use of renewable energy sources therein, pursuant to the integrated development programmes of local authorities”. According to the Cohesion Policy Funds Management Information System, by 1st January 2022, within the framework of measure 4.2.1.2 134 projects were approved and the implementation gave a reduction of annual primary energy consumption of 48496 MWh (0.175 PJ). Within the framework of specific support objective 4.2.2 147 projects were approved and a reduction of annual primary energy consumption of 23862 MWh (0.086 PJ) was achieved. The total annual primary energy savings are 72358 MWh (0.26 PJ). Latvia’s National Energy and Climate Plan for 2021-2030 determines the reduction target of primary energy consumption - 165-170 PJ by 2030. In 2020, primary energy consumption was 180.4 PJ, which means that a reduction of 10-15 PJ is required over a 10-year period. Measures supported by EU funds in non-residential buildings contribute in the amount of 2.6% of national targets.
