Information on a cogeneration unit in the building
If you use a cogeneration unit in your building please ensure that you have entered either the natural gas, fuel oil (diesel) or biogas consumption in section (10) either in the column “space heating” or in the column “total”. In the table fill in the overall annual electricity production of the cogeneration unit. Finally, insert the electricity production of the unit that was not consumed within your building and therefore fed into the grid in the second line.
Example B: Cogeneration unit in the building
A cogeneration unit in the building provides space and water heating. Its consumption amounts to 303.000 kWh. Since you do not know the part of gas used for water heating enter the total gas consumption of the cogeneration unit in the field “total” in section (10) and select “natural gas”. 100.000 kWh of electricity were produced by the cogeneration unit. Thereof, 90.000 kWh were consumed by the building and 10.000 kWh were fed into the grid. This information has to be entered in section (13).
