Leon's Greenhouses (currently in Kingston, OK but for sale because Leon wants to retire) has a model with doors on both ends plus a triangular shape on the top what has vents all along it.
The reason for that is greenhouses in Oklahoma get too hot in the summer to use. But by opening all those vents and both doors you can let the heat out and a breeze in.
I believe they redesigned the vents so that rain won't come in even when they're open. They had photos on their website and at
Facebook, but those are not available to link.
On my hard drive I have some; however, you can't upload images to Permies for security reasons. If you reached out to me elsewhere (search for GrowMap) I could send them to you.
The cheapest way to moderate temperatures in a greenhouse is by using geothermal pipes buried in the ground. The temperature below the freeze line stays the same year round.
Done correctly, the greenhouse pulls cold air up in the summer and warm air up in the winter. I'd love to figure out the correct specifications for taking one of Leon's greenhouses with the vents and installing geothermal under it.
Even if you have geothermal, I would still want those vents because it can go from cool to very hot quickly here.
