Work at Berkeley Lab is highly collaborative. You will therefore very quickly need to find your way to a building of some co-worker. And, that can be quite confusing. The buildings are numbered alright, but a rational geographic numbering scheme is … nonexistent. So, the best approach is to know where the up-do-date Lab site map is: here is a simple printable version, and here is an interactive version. Be careful when using Google maps: it recognizes some building numbers, but not all of them. Because many collaborations extend to UC Berkeley, you should know the site map location of the campus, too. Again, some building names on campus are recognized by Google maps, but several are not.
