The scope of the present study was to obtain accurate estimates of emissions from air pollutants and greenhouse gases stemming from residential heating in households by wood-fired installations.
In a first phase of the project, the current boiler/stove park by type and age of the installation was mapped based on an online survey. This provides a good view of the current boiler/stove park. The survey results were combined by VITO into input required to update the residential emission model EISSA-B. In addition to the current boiler/stove park the evolution of the boiler/stove park since 1990 has been estimated. The mapping of the boiler/stove park and its evolution essentially comprises 2 major aspects. On the one hand, there is the age of the boiler/stove park: what does the age distribution per type of installation look like in a certain year and how does this distribution evolve over time? On the other hand, there are the shares of the various installation and fuel types within the entire boiler/stove park: what are the shares of the various installation and fuel types to the total Flemish wood use in a given year and how do these shares per type evolve over time?
In addition to updating the boiler/stove park in EISSA-B, the software package received major upgrades. Additional functionalities for aggregation/disaggregation have been added to match the output to formats for reporting and any coupled air quality model. This updated EISSA-B tool is applied to calculate spatially disaggregated Flemish emissions stemming from residential heating in households by wood fired installations for a selection of years and pollutants.
