When you want to display a building name as well as the building address, it is simple to update the name. There are two ways to do this, described below.
Under the Information tab:
Scroll to the bottom of the page to the Location box. Click on the ellipsis (the three dots on the right). A menu will pop-up where you can click Edit.
The building name can now be updated in the building name field and once the change is saved, the building will appear with the new building name. 
Under the Specifications Tab:
The top box displayed under the Specifications tab is the Building Information box. In the box there is a field labelled Building Name. Update the name in this box, and click save. The new building name will now appear.
