Actual air temp and how it feels yes, a small breeze can give the impression of 5-6degree less temp, hence ceiling fans!
My method is not quite that anal, Simply open the house completely of a night time, then lock it up tight at 6am, as thats the coolest time of the night...in summer time
And its better than sitting in horrible horrible air con, nasty dry stuff it is:mad:
I'd not do verandahs personally, I'd have shutters, especially with the crossover in spring and autumn, where some days you wish you had full solar gain, others you wish you had none.....nothing quite like the sun streaming in and light filling a house on a cold day! or better yet, not needing the lights on at lunchtime:D
