To provide a solar radiation adjustment window that can adjust a solar shading ratio and a solar heat acquisition rate relative to an amount of solar radiation.SOLUTION: A solar radiation adjustment window 1 comprises an inner glass 6, an outer glass 7 and an intermediate glass 10. The intermediate glass 10 comprises a thermochromic glass 20 having a property that an amount of transmitted solar radiation passing through the glass is decreased as a glass temperature rises while the amount of transmitted solar radiation is increased as the glass temperature falls. A sealed hollow layer 8B is formed between the inner glass 6 and the intermediate glass 10. A hollow layer 8A for communicating with an outdoor space is formed between the outer glass 7 and the intermediate glass 10.SELECTED DRAWING: Figure 1 【課題】日射量に対する日射遮蔽率および日射熱取得率を調整できる日射調整窓を提供すること。【解決手段】日射調整窓１は、内ガラス６、外ガラス７および中間ガラス１０を備える。中間ガラス１０は、ガラス温度の上昇によって透過する透過日射量が少なくなる一方、ガラス温度の低下によって透過日射量が多くなる特性を有したサーモクロミックガラス２０によって構成される。内ガラス６および中間ガラス１０の間には密閉された中空層８Ｂが形成される。外ガラス７および中間ガラス１０の間には屋外空間に連通された中空層８Ａが形成される。【選択図】図１
