Good question. Don't know the answer. A Playa experiment and report could let us know.
Theoretically thinking, the solar radiation is going to be the same whether the air is windy or still so long as the sky is clear. And obviously, changes in atmospheric pressure (which cause the wind phenomenon) and actual wind currents and gusts would at least momentarily disrupt the "downflow chimney effect" that Buckminster Fuller postulated. And the air-pressure changes are going to have an effect on the air pressure inside the hexayurt, too. Wind is caused by a sucking effect in the atmosphere at various elevations. The push-pull of the gusts and vacuum is going to effect the flow of air in and out of the chimney and low-on-the-wall vents. Think that the severity of the disruption would depend upon how severe the windstorm and how locally active it is right around the hexayurt. And think that, certainly, a windstorm is going to lessen the amount of cooling -- because it will be interruping the downspout flow and the exhaust flow frequently. Light to moderate steady winds in a particular direction might only distort the flow, not interrupt it. Would probably have to do either computer modeling or colored smoke testing to get a good handle on this. And I doubt any of us are going to do that. But someone could report their experience with a change in comfort level during windstorms and during vernal winds. -- kenwinston ----- Original Message ----- From: Joshua Keroes To: [email protected] Sent: Monday, August 02, 2010 11:19 AM Subject: Re: [hexayurt] Re: Buckminster Fuller's Passive Cooling Effect Will the atmospheric convection "chilling effect" work when there's wind? -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
