Can whole-house fan systems be automated? Certainly, it’s technically straightforward to devise a method that turns on the whole-house fan when cooling is required and outdoor temperatures drop below indoor temperatures. However, since large openings are required for inlet airflow, doors and/or windows also must be opened—a more difficult undertaking for automation. For now, motorizing an existing door or window is a custom project.
Because operating whole-house fans usually involves opening a window in the living space, automation is atypical. But it is possible.
