Serbia is one of the few European countries that does not keep official statistics and does not have data on heating degree days. A heating degree day (HDD) represents a measure to quantify the energy needs for heating a building. In order to create a database, six meteorological stations in Serbia had been selected, for which the heating degree days were calculated for every year in the period 2010-2018. The months with the highest values of heating degree days were also determined for each year of the analyzed period. In addition to the annual level, heating degree days in the heating seasons over the analyzed period were calculated for the six selected stations, as well as the length and the average air temperature of each heating season. In Serbia, heating season officially lasts from October 15 to April 15. To determine the influence of the calculated annual heating degree days on fuelwood consumption in households in Serbia, over the period 2010-2018, multiple econometric models were formulated. The influence of the annual values of heating degree days on fuelwood consumption for household space heating in Slovenia and Croatia was analyzed, as well. The analysis of energy consumption in the households of the selected countries showed that wood fuels are mostly used for heating, primarily fuelwood. This is the reason why this type of fuel was selected for the research.

Broj stupanj-dana grijanja mjera je koja se primjenjuje za odredivanje energije potrebne zagrijanje objekta. Kako bi se formirala baza podataka, odabrano je sest meteoroloskih postaja u Srbiji za kojeje izracunan broj stupanj-dana grijanja za svaku godinu u razdoblju 2010. - 2018. Osim toga, odredeni su mjeseci s najvecim brojem stupanj-dana grijanja za svaku godinu analiziranog razdoblja. Osim na godisnjoj razini, izracunan je broj stupanj-dana grijanja u sezonama grijanja tijekom analiziranog razdoblja za sest odabranih postaja, kao i trajanje i srednja temperatura svake sezone grijanja. Sezona grijanja u Srbiji sluzbeno traje od 15. listopada do 15 travnja. Izradeni su visestruki ekonometrijski modeli kako bi se u kucanstvima u Srbiji u razdoblju 2010. - 2018. utvrdio utjecaj izracunanih godisnjih vrijednosti broja stupanj-dana grijanja na potrosnju ogrjevnog drva. Takoderje analiziran utjecaj godisnjih vrijednosti broja stupanj-dana grijanja na potrosnju ogrjevnog drva u Sloveniji i Hrvatskoj. Analiza potrosnje energije u kucanstvima u promatranim zemljama pokazala je da se za grijanje najvise iskoristava drvna biomasa, osobito ogrjevno drvo. To je i bio razlog zastoje ta vrsta goriva odabrana za istrazivanje. Kljucne rijeci: broj stupanj-dana grijanja; sezona grijanja; ogrjevno drvo; kucanstva; grijanje
