Who's in the UK and has caved in and bought air conditioning?

I am in the process of watching Run Away on Netflix.  It is set in the UK and filmed there as well.  I am not sure what specific region though.  Anyway while the shots of the country side are beautiful and green they seem less green than I remember from previous trips I've taken to England... so a question for those in the UK... with the recent rise in temperatures during the last few summers are things less green now?  Or am I remembering things through 'emerald green' tinted glasses?

The UK is consistently Grey and overcast as a general rule. Except 5-8 weeks in the summer where our insulated miserable weather houses struggle with 30C and we all think about getting aircon.  The hard bit is our walls are solid with no space for ducting of any kind, so if you have the money some people end up with free standing units.  Still rare.

I'm planning on ducting through an existing window vent (or two) 

Have just acquired a 6" duct fan that can move up to 402cfm, so hoping I can tap into some of the cooler evening air to help with night time sleeping, without going to full-on aircon at this stage.

Although, I suspect that the solid walls / roof space act as a storage heaters to some extent.

I understand the Bernoulli effect, but as Dave has mentioned there is a lot of more going on with the dynamics of airflow in a house that can cause it to be not effective.  Unfortunately, without doing quite a bit of experimentation/measurement I don't think that it will work for me.  Suffice to say, air intake with a low velocity fan with an outside to inside temperature differential and airflow to an open window in a second room works well and reversing the airflow does not.  In the intake scenario I have the fan mounted in the window and in the exhaust scenario I positioned the fan 1 m from the open window.  Unfortunately, this room does not have multiple windows so the airflow path is not straightforward and the air intake velocity at the remote window will be very low. With both windows in the same room exhaust might work better.  Pulling cold air from a second room's window through to the room you are trying to cool will work but with a lot longer time constant.
