you should have a look at the Simple 3D Buildings tagging schema:

There are many possible ways to get height informations and everyone's
using another way. It also depends on your hardware. However, the
easiest way is to just use the number of floors a building has + a
estimate on floor heights.

Btw, your question is probably better placed on the talk mailing list,
as you'd reach more mappers there. This is the dev mailing list,
dedicated for development questions.

Have fun mapping 3D ;)
