Passive Venting Gets Aggressive

Not a well written article.

There is new jargon such as "air conditioning cassettes" [?] and "insulated ventilation louvers" [?], without explanation. If the objective is "only to maintain correct ventilation levels", wouldn't that take just a fan, without AC?

The full article doesn't explain much as to hows and whys. This is altogether too typical of "green" technologies. Lots of buzzwords, little meat. This is unfortunate, because there are many good concepts out there, obscured by poor reportage.

No numbers (dry bulb, wet bulb, climate data, HP, KW); just greenie feel-goodies for the hoi polloi.

Yea, they could have simplified the wording just a bit. I think the main science is someone finally figured out, lol, instead of cooling the buildings air in a sealed building environment system, to bring in cold air at the bottom, presurizing the building, and using atmospheric vents to let hotter air out the top. I did this 10 yrs ago for a friend of mine on his mobile home. He had a peaked ceiling, so we opened a small hole in the wall to the outside at the peak, and put in a little 12 volt fan on a thermostat. When the ceiling air hit 80f, the fan came on and sucked the hot air out. A few minuits later, the central ac would kick on. As soon as the cool air hit the thermostat,the hot air out fan cut off, and the vent closed. This lowered his electric bill and kept the home cooler.

That sounds like a sensible, practical, and economical approach. The original article might also be S, P, and E, but it is hard to tell, because not much was explained in a relevant way.

It worked great. We used the fan out of a common 110v ac blow drier(hair drier). Those fans are really super little 12v dc ducted turbofans. Once you clip out the resistors and rectifier diodes, these fans run forever on 3-12 volts dc and move a lot of air. We used a little dc walwart transformer for power.
