What, they never heard of requiring an electronic, throught the wall air exchanger unit?
Solves the problem "scientifically". First, seal the building's skin air tight; then run extra wiring as needed; cut a hole in the wall, and install an air exchanger, that will bring in outside air, while exhausting inside air, in measured amounts.
Or, you could do it the old fashioned way, and open a few windows.
Or, you could go the really old fashioned way, and allow for a certain amount of infiltration.
Air Exchangers One of the most basic means of ventilating your house is through a simple air-to-air exchange system. PureAirProducts.com offers numerous options for whole house ventilation systems that do just that. Air-to-air fans expel stale, indoor air while bringing in fresh air from outside, reducing build-up of carbon dioxide inside the house. Some models, such as the FanTech system, mix incoming fresh air with re-circulated indoor air, thus providing cleaner air for you and your family to breathe. Make the smart, healthy choice for your home and choose from any of the various air exchange systems that PureAirProducts.com offers.
