I have a colleague that works in different building. I only know this colleague by name but not by the person, meaning that we never see each other face-to-face. I have a work that is dependent on this colleague. I've been trying to contact the colleague, by email and instant messaging, but the colleague is ignoring me. How do I solve this problem?

You have never met this person who is ignoring you. Fix that now.
Take a few minutes to walk over to their office, introduce yourself, and talk about the work that you need this colleague to perform.
If you sat next to this person, you would just lean over and chat to start the communication flowing. So, take a few extra steps and do the same. People who know you are far more likely to respond, than people you don't actually know.
If the other office is too far away for this to be practical, use the telephone and call.
Making a personal connection with a co-worker, rather than relying on faceless textual communication, is often far more effective in getting someone to do something that you need done.
You can always follow up with an email later, if a record of the conversation is necessary.

Exactly the same way if the colleague was located in a different continent : over official communication channels. Just because they are in the same office , different building, does not mean you have to go out of your way to get the work done.
If you have a work that depends on the participation from a certain person, inform them over email. [You've done already, good].
If they are non-responsive, loop in your higher authority (superior / manager) in the follow up reminder emails. [Couple of retries, not more than that].
- If it's the case that you both have never communicated before, and if you have a phone number (official number preferred) that you can call up, try giving them a call, introduce yourself and remind them of the help / involvement you'd need from them to get the work done.
Even then if it still gets ignored, escalate to the higher authority by dropping an email to your manager informing about the non-availability of the involvement from that person, with the copies of communication you sent out earlier.
They should be able to take it further, your job is done.
If your work is dependent on this colleague, you need to raise this with your line manager. They can then escalate to the appropriate level, or contact their counterpart in your colleague's department.
It also highlights the issue to your manager, who can take account of this when assigning work to you.
Just inform your project manager or whoever gave you this work task.
Describe how you have tried to contact this person and for what purpose, and the impact that the non-replies are having on your work. Then let your manager decide what to do about it or escalate as appropriate.
You've done what you can.
