This is a high thermal mass apartment block (105 
apartments) and yes 75 degrees is around the 
average temperature for the last few weeks

>  Are you getting sufficient breezes at night (induced or natural)?

No.  As well as less cool nights the air has been quite still.

But the point I was trying to make in my earlier 
post was that you can get used to consistent 
temperatures outside what you would think was your normal comfort range.

Because it has been consistently warm this summer 
the average temperature in our apartment has been 
several degrees higher than a 'normal' 
summer.  An unexpected effect of the consistency 
is that we have run our air-conditioner less than 
usual and have been sleeping well with just a sheet.

I'm remarking on this because I have seen many 
posts saying that bedrooms need to be quite cold 
at night for good sleeping conditions.  This 
'need' is inconsistent with a tight, well insulated high thermal mass building.

I've spent most of my life in poorly insulated 
houses (think California bungalow) with cold 
bedrooms most of the time and a few summer nights too hot to sleep.
