室内快適性を保つために環境が持つ価値を考慮した環境共生建築の計画方法に関する研究

摘要

The objective of this study is to clarify the problem and significance of introducing the constructive process focusing on the exergy in the designing process of the environmentally symbiotic architecture. We design the designing method of the environmentally symbiotic architecture based on a constructive process (Fig.1), as follow. Phase 1: Generation of the proposed plan (C1), Phase2: Simulation of the behavior of the energy in the proposed plan (C1.5), Phase3: Analysis and evaluation of the flow of exergy based on phase2 (C2). Phase4: Focusing on the particular efforts to improve the proposed plan (C3). This design method improves the proposed plan sequentially by repeating this process of phase1-4. We created exergy analysis tools used in phase2 and 3. In addition, we developed the database relationship of the flow of exergy and architectural techniques in the existing environmentally symbiotic architecture such as vernacular house, which is used in phase4. By performing design experiments actually using the design method, we examined the effectiveness and problem of the design method. By using constructive method, we generated the initial plan and revised it to improve the energy efficiency to keep the indoor climate confortable. In the process of the improvement, we paid attention to how designers on whether the focus of the improvement efforts, we examined the effectiveness of the design method. Following are results. Heat load of the proposed plan was smaller each time repeating the improvement. (Fig.3,4,5). Effective knowledge as design method of environmentally symbiotic architecture was discovered two points. First, by the rate of exergy storage, to know the time when the "warm exergy" flows into the room, it is possible to take advantage of the improvement plan to determine the time at which work effectively for building structures is warm the room. Second, knowing the relationship architectural techniques and flow of exergy in the existing environmentally symbiotic architecture helps to improve the shape with a performance plan. Future, by increasing the cases in database in the environmentally symbiotic architecture that already exists, and can be expected to be a design method suitable for the improvement of the architectural shape more.%環境共生建築の計画にエタセルギーに注目した構成的方法論を導入することの意義と課題を、設計実験の過程を事例に検討した。提案した計画手法は、エクセルギーの流れを分析し、目的に即した価値の利用を促進させることで、環境共生建築の性能を向上させることに貢献し得る。ただし、この計画手法の実効性を上げるには、潜熱、実際に即した冷暖房設定温度などを加味したシミュレーションを用いて設計実験をすること、また、既存建築のデータベースの事例を拡張することなどの課題がある。
