室内温湿環境形成寄与率による達成解析とGAを用いた調湿建材の最適利用に関する研究: 室内湿気発生源の勢力範囲解析に関する研究　その3

摘要

近年、地球環境問題を背景として，二酸化炭素削減および省エネ ルギーを目的に住宅の高断熱・高気密化が推進されている。高気密 な住宅では，居住者が排出する水蒸気や建材・家具等が放散する化 学物質が室内に蓄積され易く，結露被害や室内空気汚染の問題が顕 在化している。%Since houses and office buildings are being built to be more airtight and insular in recent years, indoor environments are often subject to high humidity. Meanwhile, moisture-conditioning materials are widely used in buildings as a result of their excellent ability to control humidity. But the materials' amount and location of their arrangement still should be discussed in order to get the optimal utilization. This study presents a multi-objective optimum design method for reliable indoor humidity environments due to the appropriate use of moisture-conditioning materials. In this paper, (1) a transient prediction of indoor air temperature and humidity in a model living room is performed by employing indices of contribution ratio of indoor climate (CRI_((C))) and contribution ratio of indoor humidity (CRI_((H))), and (2) an optimal design method is developed with genetic algorithms (GA) and those indices above. In order to confirm the validity of the proposed optimum design system, a conventional model living room with a number of moisture sources is set up as an analytical target and optimum amount and arrangement of moisture-conditioning materials as the design parameters are analyzed for reliable indoor humidity environment design. As a result, optimal solutions are obtained by means of multi-objective genetic algorithm (MOGA) and the effectiveness of the approach is demonstrated for designers.
