Upgrade cost for lvl1 = 1.25 * repair costs for lvl0, so you can calculate one from the other if the building's price is unknown.

Normally money1 is the building price in $ (for most buildings purchasable directly in the Build menu), money2 is the price in € (for some buildings in the Build menu and for most limited edition buildings). But if a buildings has a specified basecost value, it overrides money1 or money2.
