You seem very proud of your home ventilation system, and very keen to tell us all about it. Im not surprised you dont really care about the power usage to achieve that. Its quite telling that your alternative that you suggest is more power hungry air purifiers.

I however will stick with my house which uses zero external grid power to heat or ventilate it, and I can be happy in the knowledge I am not putting any drain on the national power grid for my comfort.

Also when we have power outages, which is quite often, it makes no difference to my home whatsoever.

Its OK, we can agree to disagree. You are not alone in thinking electricity is an infinite resource. Lets just keep on building houses that require more and more power to run and see where that gets us!
