ASHRAE Ventilation Recommendations and Science

[Guest guest]

Hello,

I have searched your archives for a while now and cannot find an

answer to my question.

Is there a need for dedicated fresh air ventilation in a new home if

steps are made to avoid contaminants?

Here is my premise.

Indoor air quality is primarily a concern with the following:

Asbestos - should not be an issue in new home

Carbon Monoxide, Nitrogen Oxide - should not be an issue with no gas

burning devices.

Formaldehyde - I am not sure of all the components going into the

house, but should be able to limit it significantly.

Household chemicals - we can control this and do.

Microorganisms, allergens and mold - Of these, the only one I worry

about is mold induced structural damage, which might even be worse if

higher humidity air is brought in. If humidity in the house is

controlled, this should not be an issue.

Pesticides - we can control this

Radon - not an issue in this area as far as I am aware otherwise we

should probably vent below the foundation,

Tobacco - will not be an issue

Although I understand how an old home with gas appliances, smokers, no

humidity control, etc will have problems, that is not the house I am

talking about.

It seems that bringing in hot, humid air on an ozone alert day here in

north Texas will do way more harm than good. I have asked this

question on a few forums and usually receive an answer that " because

ASHRAE says so. " What I would like is actual research to back up

ASHRAE's claims. Especially research related to my specific issues.

Any help would be appreciated.

Thanks,

Danny
