There are many different ways to control the environment inside a greenhouse. The size and height may dictate how you go about controlling the environment. If you are not planing any environmental controls, heat always rises. In a shorter greenhouse the heat cant rise as much as it would in a taller one. But if you have a window near the top of the greenhouse (preferably on on all sides) the heat will escape through the openings. You can also use a fan to draw in fresh cooler air, or even expel the warm air if placed near the top facing out.
