“Okinawa Nursing Training Center” is a new head office of Okinawa prefectural nursing association and also a training center for nurses to train various practical techniques.
We proposed a new Architectural style that could be realized only in this place and also deeply related to environment and climate of the place.
There are 4 large RC roofs that block out Okinawa's very strong summer sunlight. The roofs create a large shade underneath and we call there “lounge”. In the “lounge” , there is no air conditioning and lighting equipment. We came up with usage of natural winds, reflected sunlight and stable underground heat. The “cool-tube*” system and the openable windows to accommodate all environmental conditions automatically work well to keep “lounge” comfortable through a whole year.
We set up air conditioning machine only for some rooms facing the "lounge" and this minimum usage of artificial devices contribute to reduction of environmental impacts and running costs.
At the same time, people can feel vibrant wherever they are due to the continuous atrium.
"A ground-coupled heat exchanger." It is a eco-system to cool or warm air by utilizing geothermal heat.
