- Abstract
Inefficient heat use in old multi-fiat residential buildings causes problems to the residents spending a large part of their incomes on heat bills as well as for the State working towards achieving goals of energy efficiency increase, climate change mitigation and energy security. However, the Lithuanian program of multifiat building renovation keeps stalling, and therefore danger that much of this energy saving potential will go unrealised appears. The paper is concerned with the problems that arise when renovating multi-fiat buildings according to the existing legislation. In this case, the emphasis is placed on the factors that have influence on decisions made by building owners to either participate or not in the renovation program. The paper demonstrates that the currently employed method of evaluating building renovation projects does not correctly reflect the benefits of refurbishment and gives financially unattractive financial indicators. Thus, the new method of investment distribution is introduced considering three aspects of benefits for building renovation. The case analysed demonstrates how the suggested "ternary benefit" method could be used for differentiating between financing sources and presenting relevant information to the building owners. Another related problem is heat saving assessment in the building refurbishment process. The paper argues that energy audits are far more suitable for the evaluation of modernisation projects than for energy performance certification.
