Pah! You ignored the other statement in Wayne's post that "this
organisation is a small government department".

Then the building is ridiculously designed. What sort of architect
would deliberately make a building too hot so that more has to be spent
on cooling it than would ever have to be spent on heating it?

I am assuming a typical small government department office in Britain,
where heating is required for most of the year.

But not a random guess. You can approximate the truth by making
reasonable assumptions. Which is what I've done.
