開口部における近赤外域日射の遮蔽による省エネルギー効果

摘要

This paper presents actual performance of the solar shielding blinds and films that can be easily installed to not only the new-built but also the existing building. Spectral reflectivity and transmissivity are measured that includes the range of the solar radiation, and actual performance of the solar shading, effect of the thermal environment and characteristics of the transmit daylight are also investigated. Finally, effect of the energy conservation in the office building is verified by the annual heat load simulation based on the actual measurement.%市販の遮熱ブラインドおよび遮熱フイルムを対象とした紫外可視rn光域?近赤外域を含めた光学特性の実測，実使用状況を想定した熱?rn光?視環境の実測，実測結果に基づくシミュレーションによって，rnこれらの日射遮蔽手法を各種窓システムに適用した場合のオフィスrnビルにおける年間熱負荷?照明電力消費量の比較検討を行い，以下rnの結果を得た．
