I'm in the process of updating my home including whole house sealing. Part of it is an air exchange system that brings in outside air and matches that air to the interior temp and humidity before circulating.
I'm not sure if you're talking about an energy recovery ventilator, but if you're not, you should use one for that. It uses selectively permeable membranes to transfer HVAC exhaust heat and humidity to incoming air. They can recover like 85 to 95% of the energy difference between the air streams. They're pretty cheap now too - totally worth it.
Beware of sealing things that weren't intended to be sealed - for example, a crawlspace may have been designed to be ventilated, and sealing above or around it can lead to rot in the cross-members under the floor.
