1. Azizuddin Abd Aziz, Daisuke Sumiyoshi, Yasunori Akashi, Low cost humidity controlled air-conditioning system for building energy savings in tropical climate, Journal of Building Engineering, 10.1016/j.jobe.2017.03.005, 11, 9-16, 2017.05, The viable solution to the high latent load that naturally occurs in tropical regions requires an alternative system that runs at relatively low energy consumption yet be able to provide indoor thermal comfort by effective handling of the excessive humidity. Although the existing outdoor air treatment system is a proven approach, it is unpopular in developing countries due to its high initial cost. In this paper, a new system termed Dual Air Handling Unit system is proposed to be the answer. The function of Humidity-control Air Handling Unit is to remove the moisture from the conditioned room up to the desired humidity level and in the process the room temperature is also fractionally reduced. The Temperature-control Air Handling Unit completes the task by removing the remaining sensible heat so that the room temperature is maintained at the required set-point. By reducing the relative humidity to 50%, a much lower value than that of the normal air-conditioning could offer, room temperature of the new system is shifted higher to 26 °C in order to reduce the energy consumption. The simulation result shows that the proposed system offers energy savings up to 13.2% compared to the conventional air-conditioning system, without compromising the thermal comfort of the occupants..
2. Takahiro Yamamoto, Koshiro Amatatsu, Daisuke Sumiyoshi, Estimation energy saving effects of sharing fuel cell with two households by simulation program
Study on effective usage of the home fuel cell in the apartment housing, Journal of Environmental Engineering (Japan), 10.3130/aije.83.365, 83, 746, 365-374, 2018.04, The purpose of this study is to propose an introduction method of fuel cells to households of apartments. This paper examined, with simulation, the effects of sharing fuel cell with multiple households. Introduction methods of normal types of fuel cells would tend to have less of an energy-saving effect on households with fewer members (households consisting of one person or households consisting of one couple), because the load of electric power or water heating system tends to be small. Therefore, this study examined effects of energy saving in sharing one fuel cell between two households. It was verified that, when diversified combinations of load patterns were simulated for two households sharing system, this method could have sufficient effects..

4. Azizuddin Abd Aziz, Daisuke Sumiyoshi, Yasunori Akashi, Design procedure for dual air handling unit of air-conditioning system, 2018 UTP-UMP-VIT Symposium on Energy Systems, SES 2018 MATEC Web of Conferences, 10.1051/matecconf/201822504016, 225, 2018.11, The use of conventional air-conditioning system in tropical climate is ineffective to reduce the humidity. In a typical application, the indoor temperature has to be overcooled to decrease the humidity which has an inherent effect of high energy consumption. The introduction of dual air handling unit (AHU) is the answer to high humidity environment. Each AHU is tasked to control the parameter of temperature and humidity respectively according to the desired value. In this paper, the objective is to design the procedure of sizing the dual AHU so that the control system could run efficiently. Basically, eight (8) steps are necessary to size the dual AHU system and the procedure requires sequential manner. Namely, the design process are indoor design condition, fresh air flow, outdoor design condition, room cooling load, capacity of both AHUs, supply air temperature of second AHU, supply air temperature of first AHU and the enthalpy of both AHUs. The design procedure also requires a psychrometric chart to indicate the air thermal condition throughout the cycle of the air-conditioning system. In conclusion, the proposed design procedure is simple yet effective for the application of dual AHU system to handle the excessive latent heat environment..

Takahiro Ueno, Kentaro Takahashi, Daisuke Sumiyoshi, Estimation for energy demand fluctuation in commercial and business area by Monte Carlo simulation, Journal of Environmental Engineering (Japan), 10.3130/aije.84.291, 84, 757, 291-301, 2019.03, This paper describes development of the energy demand estimation method for non-residential buildings and the demand analysis in Japanese business area by using this method. We developed a method and a program to estimate demand of electricity and heat (heating, cooling and hot water) of non-residential buildings for one year. This program makes fluctuation in demand by 5-minutes intervals to reproduce the actual fluctuation depending on the type of buildings, total floor area, outdoor air temperature and so on. We can consider ideal based on the demand data..

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..
