We are going through a time when environmental, economic and social concerns, intensely amplified by climate change, by the depletion of resources, are growing. In this context, setting targets such as reducing energy consumption in the buildings sector, energy efficiency, and the use of renewable energies are becoming a priority, both at national and international level. Improving the energy efficiency of the existing building stock is important, not only for achieving national medium-term energy efficiency targets, but also for meeting the long-term objectives of the strategy on climate change and the transition to a competitive low-carbon economy by 2050 (https://energy.ec.europa.eu/system/files/2014-11/2014_article4_ro_romania_0.pdf). Currently, the building is considered as a structure in a continuous evolution, which in time through maintenance, rehabilitation and modernization works will meet the requirements expressed by the user. The case study presented in the paper presents an analysis from the point of view of improving the energy efficiency, reducing the energy requirement in a building using passive energy-saving measures, that is, the additional thermal insulation of an element of the building envelope. The materials selected for this research are: expanded polystyrene, basaltic mineral wool and cellulose fibres.
