You can ventilate by opening the windows on a regular basis. Usually that doesn't work all to well and it is expensive. Through your opened window you'll loose the energy you want to keep inside your house.

A controlled home ventilation (CHV) provides you with fresh air 24/7 and a device for recovering the energy will get more than 90% of the energy of the air extracted out of your rooms and gives it back into the air, that is flown into your house.
