Our cube-shaped modular chamber operates independently without a power source and can be quickly assembled or dismantled within three days. It serves as an emergency shelter during disasters and can be immediately converted into a medical facility with a negative/positive pressure system during infectious disease outbreaks. Utilizing digital twin technology, it allows real-time monitoring and control of air flow to maintain disease prevention and comfort. With energy-saving technology and an efficient design, it provides a stable and comfortable environment even in crisis situations. This system embodies the concept of 'Human Security for All,' ensuring effective responses during emergencies.
