Abstract
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.
Highlights
Heating degree days can be explained as a way of climate influence on energy consumption for household space heating
By formulating multiinple econometric models, it was determined that the changes in heating degree days in Novi Sad, Loznica, Zlatibor and Vranje have the greatest influence on fuelwood consumption in households in Serbia

Summary
Heating degree days can be explained as a way of climate influence on energy consumption for household space heating. Calculation of heating degree days is based on the height of the daily average air outdoor temperature values and the length of the heating season. Both of these variables depend on the type of climate that is characteristic of a particular area. Heating degree days have been analyzed in a large number of countries around the world (Belova et al, 2018; Shen et al, 2016; Spinoni et al, 2015; Sivak, 2009; Matzarakis et al, 2004).
