Solar operated shutters and vents. Most of the availble technolgy is pretty basic and affordable with your own labor provided. Solar panels for generation of electricty are coming down in price but still rather costly depending on what you grow. I have provided some book references that I have from my own work in this area that will be helpful. Some may seem old but the basics have not changed a lot.
