Emissions tab on Legislative Region Templates Dialog.
The factors on this tab define the amount of carbon dioxide emitted per unit of energy consumed for each of the major fuel types in the region. The CO2 emission factors depend on the mix of technology used to generated the electricity, the quality of the fuel and other factors such as production carbon cost.
CO2 emissions are calculated in DesignBuilder by multiplying fuel consumption by the kg CO2 per kWh conversion factor for that fuel. Conversion factors can be made specific to the region by going to the site level and Region tab and changing the data for the region. You’ll need to copy the default region first, edit the copy and select the copy as DesignBuilder library data cannot be edited. Recent CO2 conversion factors are provided with the installation for some European countries but you should check values used and if necessary enter specific values as described above.
