CaHermit, what you need is a root cellar, if you have a basement. you will need to build a stud framed insulated room next to a north facing window, as you know basement will stay cooler inside this room which could be about 6'x8' you could make separate areas for different food storage, you see some food veggies like high humidity and cool temps some like cold temps and some like medium humidity.
So lets say you have your room built put the veggies that like high humidity next to the window and install a swamp cooler for summer storage, it will make it cooler and moister next to the window. in the winter just open the window and close to maintain temp levels. in winter a humidifier will help keep humidity at the levels you want. As you have guessed I am assuming your in a hot area of Cali,
If you don't have a basement you will need to build a underground cellar. I will post more info on this later,self canned foods require a cool dark place and they should last about a year, but always check the seal before using and check color and smell.
As for the meats, you will need a freezer or you will need to learn how to dry or cure the meat. there are several way to cure, salt brine, air dried, jerky, I can't write all of the ways here today but will post a new post tomorrow or later tonight.
If you need more info contact me by PM and I will send you some plans...
