Use of large glass areas usually requires some controls for privacy, both in the daytime and at night. Obvious controls include draperies and blinds.

Consideration must be given to the size and the placement of these hangings so that they do not cancel the benefits of breeze. The use of louvres or other opaque types of ventilating units which do not have to be draped is one solution to this problem of privacy with ventilation.

Placing windows high in the wall is another effective means of obtaining privacy, especially in bedrooms.

Even though the glass area is large, the occupants of the house can have privacy.
