The Latvian capital, Riga, has an extensive legacy of Soviet-era standard buildings, concentrated mainly in large-scale residential areas throughout the city. On the other hand, the central part of the city has many late nineteenth- and early twentieth-century buildings, most of which are located in the cultural heritage protection zone. In both cases, there are pressing issues of improving buildings' condition and energy efficiency. The experience of Riga in promoting the energy efficiency of buildings through various planned measures is examined here. It is not sufficient to rely solely on the residents' initiative to improve their property's energy efficiency, as the residents' financial situation, combined with a lack of information, is often the main reason for passivity in making decisions on building renovation measures. Therefore, the involvement of the municipality and other institutions is needed to explain and promote the benefits of renovation and energy efficiency improvement and the possibilities of financial support to residents, as well as to support them in obtaining financing and renovation. At the national level, some institutions and mechanisms focus on financial aid for energy efficiency renovations in typical buildings and on studying energy efficiency scenarios in the context of heritage conservation.
