[Greenbuilding] Al Pex for Solar Heating System

Fri Jan 4 16:25:50 CST 2008

Curious, Donald. I'm not quite sure what googling me had to do with the 
question. I asked very specific questions, and made very specific 
observations. It seems rather like you have some agenda here, with this 
site or man. Anyway, as I've asked all along, if you have any 
substantive PERFORMANCE data or any other information about some of 
these loosely-alluded-to technologies, I'd be interested to take a look 
at them. I'm not trying to be negative, just pertinent...

Really, have others heard of Edmond Krecke before this? Maybe I'm just 
out of the loop. Any further specifics on his technological ideas? Looks 
like he's tied into the Passive House movement maybe. I just haven't 
really seen substantive stuff on line yet.
