A couple of years back I posted a question .. didn't get very far, thought
I'd try again.

I have a modern highly insulated 2 storey house, and this time of year the
upstairs get very hot .... and with high values of insulation it does not
cool quickly ... bedrooms are very hot.

In the US they have a very good solution "Whole-House fans" when temp
drops outside in the evening you switch these on, being fitted on upstairs
ceiling it vents the warmest air in the house into attic space, this air
then being replaced by air form downstairs windows being put in vent
position.

I have been unable to find a manufacturer in Europe .... anybody out there
know of one ?
Getting fans & remote control would not be difficult, but having
'actuating motors that open the insulated doors would appear a lot more
problematic.

Welcome comments from anyone who may have looked into this.

I could buy the US items and run off a 220 - 110V converter .. but it
would not be cheap to ship over plus 20% VAT on import.

I have a highly insulated house.
I just open some windows.
The reason it remains hot is likely to be stored heat in the house
structure. (Thermal mass)

Whole house ventilation is a waste of space.
A stupid fad that came and went about ten years ago.
I know several people that have it and have shut it down.
As you have now realised, it doesn't work in domestic houses.
Fine in intensively occupied commercial spaces.

The attic will likely be even warmer than anywhere in the house in Summer.
