Which of these is correct?:

(1)あの大きな建物は病院です。
(2)あの大きい建物は病院です。

My textbook is telling me the first one is correct which confused me since I thought adjectives were used like in the second one.
Then it says:
あの大きな白い建物は病院です。
Is there something special going on with 大きい that doesn't happen with 白い?

If the first one is correct can anyone explain why? If not, that's okay. Just knowing which one is correct will help me figure it out. Maybe. Hopefully..I'm just not good with adjectives apparently.
