Howdy two story home using the method of opening windows on lower level and opening windows on upper to cool it. We do have a door in master bedroom when i open it the rate of air movement increases enough that i can feel a breeze. My question is if i close that exterior door and just have the 4 windows open why does the air not move as much? The windows are screened but easily add up to the area of the open door. They open 2' lower then the doors height.
Is it just that a little higher opening allows the hot air to escape by convection?
If so then would it not cool better if the upper windows open top glass down verses the norm of bottom up?
Anyone using a solar chimney for cooling home verses windows?
