Short summary

Das „Netto-Null-Haus“ ist ein begehbares Miniaturhaus, das klimaneutrales Bauen spielerisch erlebbar macht. Kinder und Familien bauen es gemeinsam und lernen dabei zentrale Prinzipien wie Dämmung, Energie und Materialkreisläufe. So wird Netto-Null verständlich, greifbar und alltagsnah vermittelt.

What should be created?
In the face of the climate crisis, the abstract goal of net-zero emissions is often perceived as technical and distant. This pilot project deliberately takes a different approach: it translates "net zero" into a tangible, playful experience – on the scale of a small miniature house for children. Under the title The Net-Zero House in Miniature Format, a walk-in, child-friendly hut is being created that combines all the essential elements of a climate-neutral house - but in a reduced, understandable and directly tangible way. The project is aimed at children, families and visitors and invites them not only to understand sustainability, but to actively discover it. At the center is a small "cabane", built from regenerative materials such as clay, straw and wood. Despite its simple and playful nature, it integrates the basic principles of a net-zero building: good insulation, passive energy use, circular thinking, resource conservation. Everything is made visible, explained and allowed to be touched. A central component of the project is the collaborative construction process: children build the miniature house themselves together with their parents. With simple tools and under guidance, they design walls, insulation, roof and interior with their own hands. The result is not just an object, but a shared experience that combines knowledge, creativity and collaboration. Children can then enter the miniature house, play in it and learn at the same time: How does a house stay warm or cool? Where does energy come from? What does it mean to build with natural materials? For adults and professionals, the miniature house becomes a didactic model – a reduced but real version of what often seems complex on a large scale. The miniature house thus becomes a metaphor: it shows that climate-neutral construction is not a distant ideal, but can be concrete, simple and accessible. For children, it is a place of play and discovery; for adults an impulse for reflection and implementation; a shared space of experience for everyone. The miniature house is deliberately designed to be simple and partly ephemeral. But its effect goes beyond that: what is experienced here on a small scale can be further developed on a large scale. In this way, a playful miniature house becomes a concrete step towards a building culture that not only calculates net zero, but makes it tangible.
