Heat recovery ventilation can bring in fresh air with about half the heat loss, but it needs regular maintenance.
You can also look at whole house dehumidifiers to take the water out of the air to help reduce the mold problem.

Yes. Matt Risinger has a really good channel on building science, and this video is a pretty good intro on air tight houses and ventilation:

Go through the archives as well. Lot's of good stuff.
He's based in Austin, TX, so needs to worry about heat and humidity being kept out, but the principles also apply for colder climate where the cold needs to stay on the outside.
Another good person is Lstiburek, and his concept of the "perfect wall":

My house is absolutely frigid during the winter, and I got quote for resealing it. He told me that afterwards I am either going to have to leave my windows open (no thanks!) or live with mold.
I've heard that you can install vents, but can't find useful info. My grandparents had a chute vent, and it somehow became a breeding ground for flies and all sorts of ichies. Not sure why.
And short vents sound to me like an always open wondow, which just brings in the cold.
I want the insulation, the circulation, the breathability and the warmth. Is there any way to have it all?
