Brick cooling chambers – also known as “zero energy cool chambers (ZECCs)” – can be made from locally available materials including bricks, sand, wood, dry grass, gunny/burlap sack, and twine. By providing a cool humid environment, brick cooling chambers can improve the shelf life of many common fruits and vegetables. D-Lab has conducted research projects evaluating the performance of these devices and is working with partners in several countries to disseminate this technology.
