When you'd hear it
This is common in everyday conversation, including shops, restaurants, and dramas, where it often introduces a situation before a request or suggestion. It also appears in writing, but casual spoken uses are especially frequent.
What learners get wrong
The first clause lays the ground for the second: 추운데 창문을 닫을까요? Same shapes as the contrast sense - -ㄴ데 on a vowel-final adjective, -은데 on a consonant-final one, -는데 on a present-tense verb, -았/었는데 in the past. Unlike -아/어서 it can lead into a question, a request or a suggestion, which is what makes it so common in conversation.
