International Journal of Sustainable Lighting https://lightingjournal.org/index.php/path <p><strong>Introduction</strong></p> <p>The International Journal of Sustainable Lighting (IJSL) is the successor of the former Ingineria Iluminatului - Journal of Lighting Engineering, issued in Romania starting with 1999. IJSL aims to become an internationally recognized journal and to complement the existing prestigious lighting journals with an emphasis on emerging lighting issues including light pollution, chronobiology, sustainable buildings by extending its readers and authors to the worldwide lighting communities. The IJSL is an open access journal and is published bi-annaully in June, and December each year.</p> <p><strong>Aims and Scope</strong></p> <p>The International Journal of Sustainable Lighting is based on a change of paradigm from energy-efficiency to trans-disciplinarity (including energy, ecology, biology, green buildings, astronomy); it is a peer reviewed scientific journal encompassing experimental, theoretical and applied research results with respect to field of sustainable lighting. It provides a forum for architects, engineers, biologists and researchers involved in the design, operation, construction and utilization of lighting.</p> <p>The foremost objective is to give a quality online publication to our readers and authors. In this pursuit, our effort focuses upon quality publishing and an unquestioned commitment to the highest standards of professional and corporate ethics.</p> <p><strong>Editors-in-Chief</strong></p> <p>Jeong Tai Kim, Professor, Kyung Hee University, Republic of Korea</p> <p>Dorin Beu, Professor, Technical University of Cluj-Napoca, Romania</p> <p><strong>Executive Editor</strong></p> <p>Geun Young Yun, Associate Professor, Kyung Hee University, Republic of Korea</p> <p>&nbsp;</p> <p>&nbsp;</p> International Journal of Sustainable Lighting en-US International Journal of Sustainable Lighting 2586-1247 <p>All International Journal of Sustainable Lighting (IJSL) content is Open Access, meaning it is accessible online without fee under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by-nc-nd/4.0). &nbsp;For any reuse, redistribution, or reproduction of a work, users must clarify the license terms under which the work was produced.

It computes the star radiance from the photometric data in Gaia and Hipparcos catalogues, adding the contributions of the diffuse galactic and extragalactic light, zodiacal light and airglow, and taking into account the effects of atmospheric attenuation and scattering. The model allows computing the natural sky brightness in any given photometric band for a ground-based observer, if appropriate transformations from the Gaia bands are available. In this work we present the most recent improvements of the model, including the use of Gaia EDR3 data, the inclusion of a wide set of photometric bands and the derivation of additional sky brightness indicators, as the horizontal irradiance and the average hemispheric radiance.</p> Eduard Masana Salva Bará Josep Manel Carrasco Salvador José Ribas Copyright (c) 2022 Eduard Masana, Salva Bará, Josep Manel Carrasco, Salvador José Ribas http://creativecommons.org/licenses/by-nc-nd/4.0 2022-03-30 2022-03-30 24 1 1 12 10.26607/ijsl.v24i1.119 The Biological Effects of Light Pollution on Terrestrial and Marine Organisms https://lightingjournal.org/index.php/path/article/view/121 <p>Humans first began using artificial light at night (ALAN) during the industrial revolution and sources of light have diversified and intensified considerably over the last century. Light pollution has previously been defined under two separate branches, “ecological light pollution” where the natural light patterns are altered in marine and terrestrial environments, and “astronomical light pollution” where the view of the night sky is reduced. Natural light is vital for the regulation of animal behaviour and interactions. Surprisingly, this environmental stressor did not become a worldwide concern until 2009. Since then, research into this subject has substantially increased, with studies highlighting the detrimental effects of ALAN. These effects can be serious for many organisms and include the disruption of the essential circadian rhythms that most organisms use to time important behaviours such as foraging, reproduction, and sleep. Whether all organisms possess phenotypic plasticity to effectively adapt to increasing and changing artificial light pollution is not yet known. Here, we summarise the effects of light pollution among many different species, from marine to terrestrial, with a focus on the areas that require further research to enhance our knowledge of this subject. The aim of this review is to raise awareness and enhance understanding about this little-discussed environmental concern, including some novel ideas on camouflage and polarised light pollution, hopefully encouraging future research into the effects of light pollution on organism behaviour.&nbsp;</p> Octavia Brayley Dr Martin How Dr Andrew Wakefield Copyright (c) 2022 Octavia Brayley, Dr Martin How, Dr Andrew Wakefield http://creativecommons.org/licenses/by-nc-nd/4.0 2022-03-30 2022-03-30 24 1 13 38 10.26607/ijsl.v24i1.121
