Solar exposure condition improvement in urban area using light guide

Abstract

Abstract. This article provides an overview of the light guides and lighting systems used to improve the natural lighting conditions of the premises with insufficient lighting comfort. The retrospective of occurrence of the light guides from the 19th century to the present time is shown. The relationship between the modern light guides and light-guide and other lighting systems that have been developed since the middle of the 19th century is demonstrated. The relevance of the use of light guides during the construction and reconstruction of urban buildings is considered. The article describes the classification of light guides developed by the author, and shows the classification of light guides proposed by Aizenberg J.B. For the first time it was proposed to use light guides to improve the conditions of solar exposure of the shaded buildings. The example of two buildings shows a scheme for the use of light guides to improve the solar exposure conditions of the shaded buildings of the urban area. Setting of the tasks to be carried out to consider the use of the light guides in order to improve insolation conditions is completed.

Efektivitas Daylight Mirror Shaft sebagai Sistem Pencahayaan Alami Ruang Bawah Tanah pada Langit Tropis

“…Secara singkat, daylight mirror shaft merupakan sistem pencahayaan alami yang memanfaatkan bidang pemantul berupa cermin untuk memantulkan cahaya alami menuju ruang bawah tanah. Keuntungan sistem tersebut adalah sifatnya yang pasif serta perawatan yang tidak memakan banyak biaya maupun energi (Gritsiyenko and Kasyanov, 2017). Daylight mirror shaft telah diperkenalkan dan diterapkan pada belahan dunia bagian utara, terutama di negara-negara Eropa, Amerika Serikat, serta negara-negara Arab, yang tentunya memiliki kondisi langit yang berbeda dibandingkan langit tropis di Indonesia.…”
