This farm combines a poultry farm for 7000 hens on top, submerged LED cultivation below, and an evocative factory that facilitates the processing of products from both farms in the middle. Fresh eggs and crops are also combined into a new range of products. Technologies that minimize the ecological footprint and are based on circular principles are aimed for on all levels of the farm. The mostly submerged level of crop production keeps a constant temperature and recirculates warm humid air. An efficient air- and energy system greatly reduces emissions of poultry dust and nitrogen. Chicken manure will be dried into fertiliser granules for consumers. A frame of pv cells articulates the architecture and generates a high percentage of the necessary electricity. It also ensures protection from the sun for the hens underneath. The entire process can be seen by visitors along a route that takes them through each level of the farm without disturbing the processes.
