No, but generally the higher-level buildings require more energy and staff. Easiest way is to take a look at the XP levels page.

In the past I put a Black Agate on a Bowling Club which was my highest level building at the time. I now wish I had saved it for a Beach Disco or another lvl60+ building. But I'm not going to spend €5 to retrieve it from the Bowling Club.
