I just searched this forum for "Whole House Fan", but I didn't find much about them (except this and this).

I'm curious to hear what experiences you all may have with these simple and relatively inexpensive devices out in the real world.

Here are some pictures and a basic definition of the type of fans I'm talking about:

4.7.12 Alternative Systems - Ventilation Cooling (2013 CA Energy Efficiency Standards)

The CEC also maintains a list of models approved for sale in California. Does this list adequately represent the state of the art?

Or are there other emerging whole-house ventilation technologies that home professionals ought to know about?

For this discussion, let's try to not confuse an old school "Attic Fan" (which isn't designed to ventilate a conditioned space) with a "Whole House Fan" (which is).

Don't hold back!

Roderick, I see that comments here have waned since the 6th.There are a lot of comments before that. 

I want to respond to your comments about Airscape. Neil, the founder, went to a great deal of time trouble and , likely, expense to create the world's first 7 speed whole house fans that can be remotely controlled by smart phones from anywhere in the world. Then, apparently because customers were turning the systems on while away with windows closed, he announced a new vacuum sensor to inhibit his systems when windows are closed. 

His systems ARE good but the cost per CFM is a bit high, much like Tamarack. Invisco now has the latest in efficiency, a totally automatic speed control that can be remotely controlled or not, and when turned on starts the fan up at high speed for maximum cooling at temps over 85F, then the speed reduces (and power) linearly from 85 to 70F when the fan is off. There is a manual option as well for winter air changes. 

Invisco also offers thermally broken dual dampers for cold climates where IECC2012 specs are needed. 

I would be interested in your thoughts on this new product line.
