Does building a passive house, which requires a super-insulated envelope, mean that windows (even triple-glazed windows) must be limited?

Are passive houses darker inside than traditionally built homes due to fewer windows?

Yes and no. You want to place 50% of your total glazing area on the south facade of the home. This maximizes the solar collection.

Minimizing windows on the north side helps minimize heat loss.

Using these methods, homes using a passive solar orientation are by no means darker inside!
