Outline Activities
I'm researching to reduce the energy consumption in architectures.
The research themes are
-Optimization of Passive design method
-Examination of effective usage of the fuel cell system for residential housings
-Operation Optimization of air-conditioning system
-Develop the design method of air-conditioning system
-and so on
I work on variety things for the achievement of the sustainable society and world.

Daisuke Sumiyoshi, Naomiki Matsushita, Je-Hyeon Lee, and Yasunori Akashi, DEVELOPMENT OF THE AUTOMATIC OPTIMIZATION AND DEGRADATION DETECTION TOOL FOR HVAC PRIMARY SYSTEM, Building Simulation 2011, pp.1792-1799, 2011.11, In many building air-conditioning systems, the fixed set values are generally used throughout the year, concerning each set value of supply air temperature, outlet temperature, pressure, etc. However, it is possible to achieve energy-saving by the optimization of the air-conditioning system operation, which involves selecting the best set value according to the ever-changing outside environment and the thermal load of the building. In addition, equipment containing an air-conditioning system gradually degrade through everyday use. This is the reason they fail to fully demonstrate the level of performance, which was estimated when they were designed. For this reason, if we understand such a degradation condition, we could determine the appropriate timing to repair, exchange and overhaul the equipment. Moreover, we could possibly prevent complaints caused by their incapability and energy waste throughout the year.
Therefore, in this study, we developed an automatic optimization and degradation detection tool..

Educational Activities
In the graduate school course "Special Lectures on Sustainable Building Energy," we are developing classes that share information and exchange opinions that will serve as a stepping stone to solve various issues toward building a sustainable society. I aim to build the attitude of a person toward a sustainable society.
I hope that many students will recognize the challenges in the field of architecture, and lead the architecture of the coming era from Kyushu University.
