As I understand it--no engineer, just married to one---the big intake tubes run from a large, lined inspection box (like a cistern without the water) into the house. Air comes from outside, drawn down into the inspection tank, into the tubes and up into the house.

Let me say that our living room is by far one of the coolest places you will find in the DR--without A/C obviously--and anyone that has been here can attest to that..

The secret? Simple: 12 foot ceilings and an open space along the top....not too many people notice it. For extra cooling, ceiling fans (KDKs)..

The Texas White House is heated and cooled with groundwater from 300' beneath the surface using a pump. The cost is 25% of what gas or electric cooling/heating would be.

Actually, Dutch is quite easy to read, when you understand both, German and English... So, Thanks!

A picture also tells more than a thousand words (especially when you don't understand the language their in):



But then, your explanations where clear enough so that this drawing did not turn out to be a surprise. Thanks.

Lightbulb Vertruvius Effect

this is as old as early civilization with a new name. with pipes going thru well -and changing the temperature of a home with high widows to let the hot air out. Remember the cupola on colonial homes.This is taught in second year architecture class even in junior colleges. also ussing hay bales between the cilling and the roof, and walls for insulation. Wall filled with soil to slow down heat penetration and night release of heat on the outide of walls, all these keep a home around 70 degree day and night. Also look up conpact soil construction, labor intensive, great where lavor is cheap.

To my knowledge there is no such thing as a Vertruvius [sic?] Effect. But then I don't know it all.
You may however have confused it with the architectural teachings of Marcus Vitruvius Pollio, a (BC) Roman empire architect and engineer and Giovanni Battista Venturi an Italian 18th Century physicist who is quoted for discovering the Ventury effect.
Although pipes and tubes are involved, the suction effect created by differences in temperatures in those pipes is not the one described in the teachings of the Ventury effect.

The above application uses the expansion and thus movement of heated air as a means of creating the suction to pull fresher air from the pipes bellow. It is the application of a physical phenomenon to create an airflow using sun energy (thus replacing the need for a motorized fan or ventilator) coupled with the concept of cooling a home with cooler air from under ground (the later only indeed being thaught and applied in Roman architecture).
