Original scientific paper Investments in the construction of new kindergartens are at a low level in Serbia. On the other hand, the existing facilities are outdated, devastated and do not meet current regulations, especially in terms of energy efficiency. The attendance of children in such facilities represents a significant social issue and therefore, the refurbishment of these structures is necessary. This paper presents measures for energy recovery and methods of their implementation within the framework of a comprehensive revitalization of the existing kindergartens. Through a case study, an analysis of energy efficiency and cost effectiveness for three sets of measures has been conducted, the findings of which are presented and discussed. The advantages of the applied methods are listed, as well as the potential areas for the implementation of the results. In addition, some recommendations for the future research are given and the limitations in the application of the obtained results are emphasized. Keywords: cost effectiveness; energy efficiency; energy recovery measures; existing kindergarten; implementation models; Serbia Modeli implementacije mjera energetske sanacije postojećih dječjih vrtića u SrbijiIzvorni znanstveni članak Ulaganja u izgradnju novih vrtića su na nezavidnoj razini u Srbiji. S druge strane, postojeći objekti su zastarjeli, devastirani i ne ispunjavaju važeće propise, posebice u pogledu energetske učinkovitosti. Boravak djece u takvim objektima predstavlja značajan društveni problem te je stoga neophodna obnova ovih objekata. U radu su prikazane mjere energetske oporabe i metode za njihovu provedbu u okviru sveobuhvatne revitalizacije postojećih dječjih vrtića. Kroz studiju slučaja, provedena je analiza energetske i troškovne učinkovitosti za tri paketa mjera, a rezultati su prezentirani i diskutirani. Navedene su prednosti primijenjene metode, kao i potencijalna područja provedbi rezultata. Osim toga, dane su neke preporuke za buduća istraživanja, i naglašena su ograničenja u primjeni dobivenih rezultata.Ključne riječi: energetska i troškovna učinkovitost; mjere energetske oporabe; modeli provedbe; postojeći dječji vrtić; Srbija

Artworks on paper include manuscripts, prints, drawings, collages, and paintings on paper. Their preservation requires strict values of microclimate parameters, in particular temperature, humidity, radiation and illumination. Maintenance of these parameters in exhibition spaces and storages is of vital importance for collection integrity. Paper as an art medium is particularly sensitive to these factors. Employment of HVAC (Heating, Ventilating and Air Conditioning) system is recommended in order to avoid unwanted fluctuations in microclimate conditions. Intelligent control system should be used for data acquisition and activation of HVAC system when needed. In that way, the live span of these sensitive artworks can be extended and preserved for future generations.
