Abstract: Изобретение относится к строительству жилых зданий. Здание с целью экономии энергии, автономного обеспечения энергией и продуктами питания выполнено таким образом, что жилой корпус, теплица и овощной бункер соединены при помощи тросов попарно с резервуарами холодной и горячей воды и аккумулятором тепла. Тросы переброшены через блоки, закрепленные наверху лестнично-лифтовой шахты, расположенной в центре конусообразного светопрозрачного объема. Резервуары и аккумулятор тепла являются противовесами, позволяющими в зависимости от сезона менять местоположение жилого корпуса, теплицы и овощного бункера в вертикальном направлении вплоть до размещения их ниже уровня земли. Кроме того, теплица благодаря залповым выбросам аэрозоли и газа на корни растений, находящихся в вегетационных трубах, имеет возможность вместе с закрепленным с ней жилым корпусом перемещаться вокруг центральной оси, что способствует равномерной инсоляции растений и жилых помещений, а также нейтрализации геопатогенных факторов. Наряду с этим, перемещение по вертикали благодаря автоматизированной системе управления обеспечивает в здании учет астропсихофизиологических влияний. Находящиеся в основании здания пневмоподушки используют в качестве амортизаторов при опускании элементов здания, а газовую смесь - для пневмотранспорта в овощном бункере и залповых выбросов в теплице. 1 з.п. ф-лы, 6 ил.
