Okay, on a personal level this can be tricky to calculate and it is highly individualistic.

Example for Heating

A German price comparison site has done the calculation and for their model – 20m² home office and a yearly usage of ~2000 litres heating oil for the whole apartment) – you would end up with ~4% higher usage [0]. That means that you have 80 litres more heating oil which is equivalent to roughly 80 days of commuting 20 km / day via car. The German average commuter does ~32 km / day [1].
