It was heavily rain yesterday afternoon. At night, I feel my living hall down stair warm like Oven if compare to the temperature outside the house. The temperature outside the house is so pleasant and nice, I guess below 30 degree.
The upper floor also not so hot compare to none rainy day.
I am wondering why living hall down stair, especially the center of the house feel so warm, just like in the Oven.
Any thought ?

you see, after rain, the upper floor cool down a lot but the lower floor at the center of the house still warm like Oven.

If I install Wind Turbine, I think most probably the wind turbine able to cool down upper floor due to better ventilation at upper floor.
This is similar to circumstance where the upper floor cool down a lot after heavy rain.
But the ground floor at the center of the house still warm like Oven.

So I guess wind turbine only solve the heat problem on top floor and not the ground floor for a double storey terrace house.
