Abstract: A method for cultivating plants is described. The method comprises the steps of sowing seeds in the growing medium in sterilized pots (17) using a sowing device (7), allowing the seeds to germinate in a germination device (8), automatically moving the pots through a greenhouse (2) to allow the germinated seeds to grow into plants (43), harvesting the grown plants using a harvester (5), and sterilizing the pots with the growing medium in a sterilization device (6) after harvest in order to provide sterilized pots (17) with a growing medium. An arrangement for performing the method is also described.

Abstract: A high-rise building (1) is described, which comprises a building structure (2) with floor structures (3), a double-skin façade comprising a first skin (5) and a second skin (6). The high-rise building also comprises at least one conveying system (7, 7?, 7?) arranged between the skins (5, 6) of the double-skin façade and arranged for moving trays (8) vertically between the skins (5, 6) between a starting position (9, 9?, 9?) and an end position (10, 10?, 10?). The conveying system (7, 7?, 7?) comprises essentially horizontal track portions (14) each having a length axis (15), track connecting means (18) which connect the track portions (14), and conveying means for movement of the trays (8) along the length axis (15) of the track portions (14) and along the track connecting means (19).
