I think it's not bad at all, such a controlled residential ventilation system. The acquisition costs are indeed high, but the savings come with the controllable ventilation. Energy is not simply let out of the house. Also, the used air is vented out much better. Simply ventilating through the window has its disadvantages. A lot of energy is lost this way, and that costs money.
