Determining the energy needs of households in Slovakia:
Emissions from the household sector are estimated based on international methodological procedures, taking into account national conditions. The methodology is based on the calculation of emissions from consumed fuels that were used for heating and hot water in households. Minimum data are recorded for biomass consumption in households. For the most accurate estimate of consumption, the principle based on the estimation of the total energy need of households per unit area (m2) is used. The calculations include data on known fuel consumption, data on flats, the share of connected households in DH or even the climatological factor. After estimating the fuel consumed, the emissions are calculated based on a set of emission factors for the various installations used for heating and hot water.
To more accurately determine emissions in households with individual heating with solid fuels, three surveys have already been conducted in Slovakia since 2017. From the obtained data, it is possible to better determine the balance of fuel use in households with an individual heating system. The data from these statistical surveys provide us with information on the age and state of reconstruction of houses, on the energy sources used for heating and water heating, on the purchase and consumption of different types of fuel, on the technical condition and structure of combustion equipment and on the method of heating in households using primarily solid fuel. On the basis of this information obtained from surveys carried out in cooperation with the Statistical Office of the Slovak Republic, it is possible to determine emissions from the household sector with greater accuracy. The data offer us a better estimate of the consumption of biomass and fossil fuels in households, thanks to which it is possible to better estimate the emissions of greenhouse gases and pollutants from the household sector.
