昼光に関する評価指標と評価基準の特徴: 建築設計における光•視環境評価の適用に向けた研究

摘要

近年ますます深刻化する環境問題を背景に、建築分野でも建物の省ェネルギー化は必須の課題である。環境配慮型建築への期待は高まり、目標とする環境性能の確実な達成やより良い環境性能の実現のため、定量的な検討に基づいた設計が求められている。%Daylighting simulation technology is definitely helpful in architectural design, especially as technology has rapidly developed recently. However, without a thorough understanding of its indexes and criteria, a simulation can causes an undesirable and inappropriate analysis for architectural design. Based on a wide range of document investigation, this paper examines the characteristics of the daylighting indexes and criteria in order to be applicable to daylighting design in Japan. This paper clarifies the historical development of daylight evaluation such as daylight acquisition and discomfort glare, and the current situation of daylight evaluation system in Japan.
