For each energy source, default values are shown for primary energy and CO2 emission factors. These default values, which vary according to Project Location, are based on standard DINV-18599.
At the bottom of the Energy Source Factors dialog, define the building’s source or multiple sources of electricity. Click on a listed Source item and use the dropdown to specify the source of electricity (Natural gas, Propane, Oil, Wood, Coal, Nuclear energy, Wind energy, Solar energy, Water energy or Unknown).
If you use more than one energy source, click the + (plus) button, then choose an additional source. Define the Proportion of each source used so that they add up to 100%. To remove a row, click the – (minus) button.
