There are some standards in building codes these days. If you notice, all modern buildings have braille in the elevators, emergency exits, and many building signs. So they know to find them. Other than that, people with blindness are just fine with asking others where the directory for the building is, which should also be in braille, or there should be a security person nearby to answer questions.

here's an example from <a href="http://www.travels.com/destinations/australia-new-zealand/" title="australia" style="", class="stronglinks" target="_blank" />Australia</a>: http://www.braille-oz.com.au/standards.php 2.1 Location of Braille and tactile signs Signs including symbols, numbering and lettering must be designed and installed as follows: 1. Signs must be located not less than 1200mm and not higher than 1600mm above the floor or ground surface. 2. Signs with single lines of characters must have the line of tactile characters not less than 1250mm and not higher than 1350mm above the floor or ground surface. 3. Signs identifying rooms containing features or facilities listed must be located; a. On the wall on the latch side of the door with the leading edge of the sign located between 50mm and 300mm from the architrave; and b. In the event of insufficient latch side dimension, a sign may be placed on the non-latch side of the door; and c. Where (a) or (b) is not possible, the sign may be placed on the door itself.

They may just be used to where they are.

I always wondered how they know that the Snickers bar is B5 and the Payday is D2 in a vending machine, and how much the price is for each item.
