wolle刻下の地球環境問題深刻化の観点で、再生可能・持続可能エネルギーへの移行、ネット･ゼロエネルギー化を基盤とする脱炭素社会への移行は必須の課題であろう。しかしながら、脱炭素社会への移行は社会の安全と利便性を犠牲にして行う事は許されず、持続的発展の為には絶えまない安全と利便性の追求が社会発展の基本であろう。この相反する課題の解の一つは無形財の増大、サイバー・フィジカル・システムへの展開であり、恐らく、サイバー空間上でのヒトの再現が重要な技術となろう。Q-Energy Innovator Fellowship21総合理工学府総合理工学専攻博士後期課程1年総合理工学研究院 教授To realize a decarbonized society, it is essential to reduce CO2 emitted in the process of energy production and consumption as well as optimize energy consumption. About 30% of the energy consumed worldwide is reported to be consumed by buildings, of which 40% is used in HVAC (Heating, Ventilation, Air Condi-tioning) systems. For the advancement of building energy evalu-ation, it is necessary to establish a simulation technique that can accurately predict human thermal comfort and microclimate. As interest in the indoor environment increases, many comprehen-sive evaluation methods using numerical analysis such as CFD (Computational Fluid Dynamics) which are free from many re-straints such as time, cost, and ethical issues in measurement-based experimental methods, have been proposed. Recently, re-producing the human body in an indoor space for more precise IEQ (Indoor Environmental Quality) evaluation is regarded as an important factor. Against this background, CSP (Computer-Simulated Person), which can treat the special characteristics of the human body, has been suggested as a digital twin for CFD simulation. However, previous studies simplify or ignore clothing on CSP, heat/mass transfer around clothing, and have not repro-duced narrow air gaps in the intermediate zone between clothing and the human body, which have an important role as a ventila-tion layer. Accordingly, we aim to develop a new CSP with cloth-ing and propose an improved indoor environment evaluation for precise and advanced estimation of human thermal comfort in-doors. The major task of this study is as follows. First, we establish a 3D model of CSP based on the experimental thermal manikin with clothing using a 3D scanner, and high-level thermoregula-tion model was applied into CSP. To confirm the prediction accu-racy of indoor environmental simulation using CSP, we validate CFD analysis results based on the data from chamber experiment using thermal manikin. On the other hand, existing HVAC sys-tems are generally controlled based on the sensor installed at one point representing the indoor environment. However, this data from the sensor may not be representative of the environmen-tal factors in the entire space. The local environmental analysis results on IEQ and thermal comfort using CSP can be used for feedback control of HVAC systems, and more suitable ventilation airflow rate and energy requirements for air conditioning can be found. It is possible to contribute to the realization of decarbon-ization through the optimization of the operation of HVAC.指導教員からメッセージACFD Conference (Title: Development of Advanced Computer-Simulated Person for Indoor Thermal Comfort and Air Quality Assessment)伊藤 一秀For the evaluation of the indoor environment through more realistic reproductionDevelopment of Advanced Computer Simulated Person for Indoor Thermal Comfort and Air Quality AssessmentPark Hyun-Gyu16f
