集合住宅への分散型エネルギーシステムの導入可能性に関する研究

摘要

Many countries positioned the distributed energy system as a part of principal energy strategy for residential sector. For introduction of distributed energy system, such as co-generation sysytem, to residential sector, the balance between heat and electricity has to be resolved for stable and efficient operation. In this study, a statistical analysis tool is proposed for the estimation of hot water demand using a simple statistical parametric method. The parameters of statistical model proposed in this paper is derived from the factors of time lag of behaviors that based on survey on human activity patterns. The effect of number of household on hot water demand was simulated based on the aforementioned random model. In addition to the simulation study on hot water demand, the change of electricity demand was also studied especially for the time trajectory of usage pattern. The field measurement campaigns were then performed on various common locations of apartment such as lobby and service corridor. In short, the paper discusses the impact of various characteristics of apartment house onto the performance of distributed energy system. To be more precise, several key characteristics were considered such as housing type, housing scale, and width of common space.%本研究では、集合住宅における住棟単位の省エネルギー対策とし て、コージェネレーションシステムの導入を取り上げ、集合住宅共 用部の照明用電力需要と居住部の給湯需要に対してエネルギー供給 を行う場合の省エネルギー性を検討し、以下の知見が得られた。 （1）集合住宅共用部の実態調査に基づき、住棟における共用部面積 が延床面積に占める割合は増大傾向にあり、住棟形式により異なる が、15～25%を占めることが確認された。また、用途別の共用部面 積と照明機器容量の調査結果から、照明用電力帯要原単位を算出し た。
