We created a comfortable environment by implementing a radi-ant air conditioning system—a first for a performance hall in Japan. Efficient heating and cooling is provided by radiant panels installed on the backs of the audience seats and on the low ceiling at the rear section of the first- and second-floor seats. A heat pump regulates the temperature of the water used by the system, which utilizes highly treated wastewa-ter—often an untapped energy source. The result is a perfor-mance space both environmentally friendly and comfortable for users.
