The renovation of multi-apartment residential buildings requires a long-term strategy, which has already proven the activity of renovation of building is closely related to the state’s involvement and activity with the activities of the grant program. It is important to understand the strengths and weaknesses of the current grant program period up to 2023 and the future trends in state support for the renovation of multi-apartment residential buildings, in addition the financing opportunities, the choice of technologies and materials to be used. In research, used data form the program of renovation of multi-apartment residential buildings implemented by the LIAA, which was implemented during period until 2013, as well as the data of the progress report of Development Finance Institution Altum on the renovation of multi-apartment residential buildings. In research, is important to understand the main trends and characteristics of energy consumption before and after renovation of multi-apartment residential buildings need to understand the changing market trends and changes in regulatory requirements, which directly affect the choice of technology and materials, hence the variable costs of renovation. In addition, in the research simulates long-term, future energy efficiency trends after 2023 are modeled on different scenarios that consider both the commitment and targets of Latvia in the field of energy efficiency, the energy efficiency indicators of the technologies and materials used, and the different financing options for the renovation of multi-apartment residential buildings. It is important to understand what the tools might be to raise awareness among the flat owners in favor of improving the energy efficiency of housing, as well as what might be the most successful financial aid or incentive rules that would stimulate to vote in favor of renovating buildings and improving energy efficiency in multi-apartment residential buildings. The advantages and disadvantages of the current program are being assessed from the practical point of view, how the processes of the Altum (Multi-apartment building energy efficiency) program operate directly, evaluation the projects from the stage of preparation the technical documentation, the construction work, and the achieved results of the projects.
