This medical center is located a little way off a busy street. It is usually used for the local doctor’s meetings, trainings, and holiday medical services. But in the event of disaster, it will function as an emergency medical center. Considering it’s important role, our lighting concept is a "lighthouse in an emergency." We lit up the sunscreen with LEDs with a small amount of electricity that can be covered by private electric generator. Thus, the building’s façade will be lit effectively even in case of power outage and make it easily found by people who need help.
