In the exhibition hall, the soil used to construct cave dwellings is selected as the core element. In the first half of the space, soil manifests its natural traits. In the second half, after becoming rational and restrained with the assistance of science and technology, soil is reborn as the S & T soil to construct passive houses. The shape and atmosphere of the space change with the transformation of the leading role, showing the journey of “soil” rebirth. Modern display technology is combined to translate the professional concept of passive houses into interesting popular science proses.
