Some of the problems associated with assessing the retrofit effectiveness of apartment buildings in urban areas are considered. The retrofit of houses should be followed by the amelioration of their surroundings. The priority order of districts to be renovated depends on the condition of the buildings in a district and on strategic urban development programmes. In order to determine the profitability of investments in housing retrofit, a number of retrofit scenarios should be developed. The authors of this paper offer a new approach to determining the retrofit effectiveness of houses based both on expected energy savings and the increase in market value of renovated buildings. In line with the proposed approach, retrofit scenarios for apartment buildings in Vilnius were developed, i.e. retrofit investment packages for various districts were prepared and arranged in the priority order for their application according to the method of geographical analysis suggested by the authors.
Most European countries have succeeded in reducing energy consumption of new dwellings by more than 50% without increasing their building cost, and therefore, energy efficiency has achieved great acceptance among building owners . These buildings represent about 20% of the building stock but consume only 5% of energy. Concentration on improving the energetically poor building stock has great potential. The lack of interest in housing retrofit can be explained by the fact that economic interest in a building expires after 30 years.

When various retrofit scenarios for apartment buildings are evaluated, the solutions are usually based on the expected reduction in energy consumption. However, it should be mentioned that retrofit considerably improves the state of building structures as well as prolonging the lifetime of a building. The building's market value, which can be determined by applying MVR, is also raised. Therefore, the effectiveness of retrofitting an apartment building should be evaluated from various perspectives, with both energy conservation and an increase in market value taken into account. In order to make investments in building retrofit profitable, several retrofit scenarios should be developed and assessed from various perspectives. The choice of a particular retrofit scenario depends on strategic urban development programs as well as the condition of panel houses and their environment, renovation costs, saving of heat energy and the expected increment of market value of the renovated apartments. Retrofit scenarios should be based on a comprehensive approach, providing for the renovation of buildings and their surroundings. The SIR and MVR ratios may be applied to evaluating the effectiveness of retrofit scenarios.
