The distance is a little too great to even run single mode fiber without a repeater, so it would really depend on what kind of traffic will be running between buildings. You may very well need a WAN solution. You could use anything from 56k ppp, frame relay, ISDN, T1, to T3 depending on what you need to push across the link. The only other thing would be if you could jump on a SONET ring or something like that.
For the closer buildings you may also want to consider a Wireless link, depending on whether they have LOS etc. Best consulting with your local carrier provider and see what solutions they can offer you. Which country are you located in ?
