You can get this in a lot of places, with units that use the inside air to pre-condition the outside air being brought in so you're not destroying the efficiency of your HVAC system. It's called Heat Recovery Ventilation (HRV) or Energy Recovery Ventilation (ERV). Units exist for small residential buildings all the way up to massive commercial units. HRV is used in temperate climates where the humidity outside is generally not a problem, and ERV is used when the outside air needs to be dehumidified also. It's not usually a feature of residential units, but commercial ones also have a bypass for when the building management system detects (using sensors like wet-bulb thermometers) that the outside conditions are fine to bring inside, which is called the "economy cycle". It switches off the baffles to the HRV or ERV and just brings the outside air in directly. If somebody was really interested, that could be implemented at home with some extra ducting, some controllable dampers, sensors, a Raspberry Pi, etc.
