Like in comparison to a similar sized office block for example.
Let's take the example of a lower league football ground. They probably only use the floodlights once or twice a month for actual matches, but are they used outside of this? What about offices and training and stuff (if all that happens on the same site)? How many staff does the average lower league club have and do they work 9-5 mon-fri at the ground?
Asking for a friend.
