I have an 8'X8' greenhouse with automatic vents and an additional louvered window that can be opened up. I do not heat it. I use it in the winter to hold over potted plants that need just a bit of protection - my big mixed herb pots, large potted containers with miniature nectarine/peach trees, etc. I also have three big whiskey barrels in the green house that are filled with good potting soil - I grow lettuces, radicchio, kale, swiss chard, and spinach - items that are cold hardy and do great all through the winter given the protection of the greenhouse. I start these items in mid summer and have them fully grown going into the late fall - ready for harvesting throughout the winter months.
I am going to try moving my potted pepper plants in during the early fall too and see if I can keep them going this way as well.
In the spring, I use the greenhouse as my second step in seedling starting. I start them in the shop under lights and on a heat mat. As they get closer to being ready to plant out - I move them into the protection of the greenhouse to begin hardening them off and letting them "grow on" for a while longer yet. By doing that... I don't rush seedlings into the garden because I need space under the grow lights... and they transition better to the less protected environment of the garden. Right now, I have several big flats of seedlings out on the bench in the greenhouse - celery, brocolli, two kinds of onions, and leeks. During the height of the summer, I generally do not have much in the greenhouse - as the heat and humidity is really too much in there without the addition of a fanning system etc. I prefer to keep my greenhouse a low energy user (as in none!) - instead opting for it to be a great season extender.
