International Journal of Sustainable Lighting 2020-01-19T20:38:48+00:00 Geun Young Yun Open Journal Systems <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> Assessing public perceptions about road lighting in five neighborhoods of Tirana, Albania 2020-01-19T20:38:48+00:00 Kuenda Laze <p>The light use was assessed in ten indoor and outdoor environments of Tirana, Albania, in November 2017. The five indoor environments presented one lecture hall, one library and three labs in a school environment. The five major streets of the capital city of Tirana presented outdoor environments. Questionnaires were respectively used to assess two criteria of “Vista” and “Visual comfort” of daylight in indoor environments and security, obstacle detection and visibility in outdoor environments. Lighting quality aspects of “Vista” were evaluated at a higher rank compared to “Visual comfort”. The approximately 87 and 60 percent of respondents respectively were not able to detect a pavement obstacle after the sunset (dark) or to distinguish a familiar face at a distance of 5 and 10 m in outdoor environments. Lighting was respectively inadequately comfort to 86 percent of users in five indoor environments. Road lighting after dark was not satisfactory to 60 percent of respondents in outdoor environments. These initial findings identify that lighting could generally be inadequate in indoor and outdoor environments in Tirana. Further research is required on the light use in built environments in Tirana, Albania.</p> 2019-12-01T00:00:00+00:00 Copyright (c) 2019 Kuenda Laze Informing good lighting in parks through visitors’ perceptions and experiences 2020-01-19T19:55:53+00:00 Brandi Smith Jeffrey Hallo <p>Park visitors’ experiences and outdoor lighting are linked, but no studies have investigated visitor preferences for lighting in these locations, nor reasons for such preferences.&nbsp; Visitors’ preferences for lighting may help parks regulate and utilize lighting in a way that both protects resources and provides for quality night experiences.&nbsp; Brightness, Correlated Color Temperature (CCT), and context affects human perceptions of lighting.&nbsp; This paper examines these variables and related lighting preferences in settings common to parks: pathways, amphitheaters, and restrooms.&nbsp; Experimental lighting scenarios were setup at Acadia National Park for brightness ranges typical of each setting.&nbsp; CCTs were chosen based on those common for outdoor lighting – 3000K (yellow), 4200K (white), and 6000K (blue-white).&nbsp; Scenario light fixtures were operated by control boxes that enabled participants to switch between the three CCTs and to adjust brightness.&nbsp; A survey and semi-structure interviews collected data from visitors.&nbsp; Participants preferred 3000K at both the restroom and amphitheater, but 4200K at the pathway.&nbsp; A 6000K CCT was undesirable for all locations.&nbsp; Visitors’ preferred brightness ranged from 1.4 lux on the pathway to 10.5 lux at the restroom.&nbsp; The most frequently cited reasons for these choices were the desire to provide natural nighttime light levels, maintain natural darkness, create a soothing or subtle setting, and to avoid tripping or falling.&nbsp; Many participants indicated having both negative and positive experiences in parks caused by outdoor lighting. Parks must address outdoor lighting if they are to comprehensively manage the nighttime environment and nighttime visitor experiences common in these places.</p> 2019-12-02T00:00:00+00:00 Copyright (c) 2019 Brandi Smith, Jeffrey Hallo
