I think we need more pressure difference to get that air moving quicker! There’s a few things to try out with opening and closing doors and using the ERV. In other words, there are different circumstances to experiment with besides the varying weather conditions. It’s on the to-do list!

This would affect how quickly the solar chimney could gets or cool a space. I assume air moves more quickly when the temperature difference between top and bottom is greater. I suppose the temperature in the receiving space is also important. Have you experimented with moving air through the chimney under different circumstances ?
