That's the department's estimate. I didn't verify all the hypotheses on which that estimate is based, but we included it in our report to demonstrate that there are real repercussions. Indeed, even if a building is not being used or is being only partly used, it still costs money. There are operating and maintenance costs, but there are also municipal property taxes or financial compensation in lieu of property taxes to pay. If a building is not used to full capacity, it costs money.
