 So that's going to be a key right there. But ventilate it early in the morning. If you got skylights that open up, that can be a really big key as well. And that'll really keep that air moving. I've noticed when I put a skylight in the highest part of my living room there, I can open that up in the morning and it's just like a chimney and it just pulls that heat right out naturally. And if I open some lower windows, it just, I get that cross flow ventilation and it doesn't cost me any money to do it. And that's where you can save some money. So that's a good one there.
