トップライト型ポイド空間における入射光による各階の日射負荷の推定

摘要

トップライト型ポイド空間における入射光による各階の日射負荷rnを推定した．以下に，得られた成果を簡潔にまとめる．rn1）照度に関する発光効率の概念を用いて，トップライトからの入射rn光が及ぼす光環境への影響度（各階の照度分布）から熱環境へのrn影響度（各階の日射負荷）を推定する方法を提案した．%Recently, buildings that adopted the external insulation method that is possible to take the thick insulation are widely prevalent in cold regions. While the reduction of heating load in winter is generally expected, the increase of cooling load in summer is concerned. So, it is necessary to devise the buildings and facilities like natural ventilation and solar control. The aim of this paper is to estimate the solar radiation load at every floor caused by incident light in skylighted void space. Therefore, we calculate the solar irradiance using ideas of luminous efficacy about the illuminance from the illumination distribution to every floor, and show details of solar radiation load at every floor by model experiment and numerical analysis.
