Having a veritable environmental lab's worth of recording instruments on a wall I notice that the humidity must drop before the temperature starts to move downward.
The temperature starts dropping very slowly once humidity reaches 60%. If enough BTU extraction is provided, the temp drop increases once the humidity reaches 50%.
But ceiling and wall Delta T will offset temp gain. The main. Benefit being a reduction in humidity. After I connected an 80-pint dehumidifier the cooldown was faster. But that Delta T and percentage of humidity makes simple calculations difficult.
My casita under construction is going to be firred out in 2x4 with closed cell foam. It's all shaded under a large Parrota tree.
When living in the tropics in a bare concrete dwelling life means the school of hard knocks. My bus cools down much faster at night. I parked it cross ways to the tradewinds.
