I guess "cei" should have become a ceiling. Where's the rest of your post?

Which is the climate in the fan works in? Humidity, temperature at night and day?
Which are the constructional given facts like windows and walls?
What is a high ceiling? How high is high?
Are there historical or cultural aspects to be considered?
