AMFİ-DERSLİK ÖĞRENME ALANLARINDA İNSAN ODAKLI MİMARİ AYDINLATMA TASARIMI

By using artificial lighting in AMFI classrooms where there are architectural constraints and daylight cannot be adequately benefited from, it can contribute to the visual comfort and indirectly to the health of the students. In this study, point-based analysis of the Equivalent Melanopic Lux values of artificial lighting and learning environments in schools was made according to the criteria of WELL standards specified in the Human Centric Lighting concept. By using direct lighting, without changing the architectural design, optimum lighting suitable for human biology is provided with low-cost artificial lighting arrangements. According to the Human-Centered Lighting concept, an architectural lighting design was made in accordance with the WELL standards criteria. As a result of the improvement of visual comfort and optimum circadian effects in the learning environments of the students studying in AMFI classrooms, it is predicted that the success and participation of the students who use these learning areas will increase.

The Contribution of the Soviet “Kinetic” Art of the 1960s‑1970s to the Development of the Theory and Practice of Architectural Lighting Technology

The paper analyses the original works in the field of architectural light and engineering belonging to the most prominent representatives of the domestic kinetic art of the 1960s (F. Infante, V.F. Koleichuk, L.N. Nusberg, as well as A. Lanin and B.M. Galeev). The conceptual basis of these works is revealed including a special attitude to light as a unique physical phenomenon and, at the same time, the most important component of a new architectural and artistic language. The practical value of the projects of special dynamic lighting of art objects, interiors of exhibition spaces, individual architectural objects and the urban environment as a whole, proposed by these authors and partly implemented by them, is revealed. It is shown in what way and for what purpose this type of synthetic art was formed at the intersection of architecture, design and engineering, which made a significant contribution to the development of both the theory and practice of architectural light engineering. In conclusion, the idea is expressed about the importance of using the considered historical experience at the present time, when every year new technical possibilities appear for creating an expressive light-colour environment, but deep content, philosophical and theoretical foundations for its design, which inspired the masters who stood at the origins of this the most important architectural and artistic direction, are lost.

luox: novel validated open-access and open-source web platform for calculating and sharing physiologically relevant quantities for light and lighting

Light exposure has a profound impact on human physiology and behaviour. For example, light exposure at the wrong time can disrupt our circadian rhythms and acutely suppress the production of melatonin. In turn, appropriately timed light exposure can support circadian photoentrainment. Beginning with the discovery that melatonin production is acutely suppressed by bright light more than 40 years ago, understanding which aspects of light drive the 'non-visual' responses to light remains a highly active research area, with an important translational dimension and implications for "human-centric" or physiologically inspired architectural lighting design. In 2018, the International Commission on Illumination (CIE) standardised the spectral sensitivities for predicting the non-visual effects of a given spectrum of light with respect to the activation of the five photoreceptor classes in the human retina: the L, M and S cones, the rods, and the melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs). Here, we described a novel, lean, user-friendly, open-access and open-source platform for calculating quantities related to light. The platform, called luox, enables researchers and research users in chronobiology, sleep research and adjacent field to turn spectral measurements into reportable quantities. The luox code base, released under the GPL-3.0 License, is modular and therefore extendable to other spectrum-derived quantities. luox has been endorsed by the CIE following black-box validation.

POLUSI CAHAYA VIDEOTRON PADA PERSIMPANGAN JALAN TAMAN MENTENG BINTARO

Architectural lighting design aims to improve the image and aesthetics of an area or building at night known as the concept of city beautification, the lighting must also be able to meet the criteria of safety, orientation and security when implemented in areas or buildings with complex activities such as in an area adjacent to the traffic flow. Technological advances resulted in the change of commercial media communication facilities, such as static billboards turned into LED videotrons. The placement of videotrons needs to be considered on roads with motorized traffic flow, as it allows for the risk of accidents, as well as light pollution especially at night. This study used The Post Occupancy Evaluation (POE) method, the extent of the influence of videotron light on the comfort of driving a motor vehicle at the intersection of videotron Menteng Bintaro Park. The result of this research that the placement of videotron is the policy of local government, vendors and environmental managers by paying attention to the AMDAL before and after the facilities are installed, with road safety complementary facilities such as road boundaries and shock lines. Information about commercial advertisements on videotron Taman Menteng Bintaro as much as 80% for pedestrians and motorists get the information, compared to motorists as much as 60% do not get information. The light effect of videotron greatly affects the surrounding environment and there is a glare effect of light that changes suddenly with results for pedestrians (80%), motorists (60%) and the least of the motorists (50%), because of the more comfortable condition in driving. Desain pencahayaan arsitektural bertujuan untuk meningkatkan citra dan estetika sebuah kawasan atau bangunan pada malam hari yang dikenal dengan konsep city beautification, pencahayaan tersebut juga harus mampu memenuhi kriteria keselamatan, orientasi dan keamanan ketika diimplementasikan pada kawasan atau bangunan dengan aktivitas yang kompleks seperti pada sebuah kawasan yang berdekatan dengan arus lalu lintas. Kemajuan teknologi mengakibatkan perubahan sarana komunikasi media komersial, seperti papan reklame yang statis berubah menjadi videotron LED. Penempatan videotron perlu diperhatikan pada jalan dengan arus lalu lintas kendaran bermotor, karena memungkinkan untuk terjadinya resiko kecelakaan, serta polusi cahaya terutama pada malam hari. Penelitian ini menggunakan metoda Post Occupancy Evaluation (POE), sejauh mana pengaruh cahaya videotron terhadap kenyamanan mengemudi kendaraan bermotor di persimpangan videotron Taman Menteng Bintaro. Hasil penelitian ini adalah bahwa penempatan videotron merupakan kebijakan Pemda, vendor dan pengelola lingkungan dengan memperhatikan AMDAL sebelum dan sesudah fasilitas terpasang, dengan fasilitas pelengkap keamanan jalan seperti batas jalan dan garis kejut. Informasi mengenai iklan komersial pada videotron Taman Menteng Bintaro sebanyak 80% untuk pejalan kaki dan pengendara mobil mendapatkan informasinya, berbanding terbalik dengan pengendara motor sebanyak 60% tidak mendapatkan informasi. Efek cahaya dari videotron sangat mempengaruhi lingkungan sekitar dan terjadi efek silau dari cahaya yang berubah secara tiba-tiba dengan hasil untuk pejalan kaki (80%), pengendara motor (60%) dan paling sedikit dari pengendara mobil (50%), karena kondisi yang lebih nyaman dalam berkendara.

THE METHOD FOR EVALUATION THE CHARACTERISTICS OF ARCHITECTURAL LIGHTING OF BUILDINGS

The variety of modern technologies and the versatility of lighting solutions in architectural structures necessitate a method for evaluating such solutions. In this article, a method for assessing the characteristics of architectural lighting of buildings is graphically demonstrated, based on the example of architectural lighting of a public building in the city of Voronezh. The proposed method involves the identification of qualitative indicators of the expressiveness of architectural lighting of facades and their quantitative assessment using an integrated approach from the standpoint of the selected characteristics and criteria. Thanks to this method, the strengths and weaknesses of the studied architectural lighting of the building are clearly identified for its subsequent modernization or the creation of promising conclusions for the design of new construction objects.

A Hybrid Effectiveness-Implementation Study of a Multi-Component Lighting Intervention for Hospital Shift Workers

Simple lighting solutions may mitigate the harmful effects of shiftwork. This hybrid effectiveness–implementation study evaluated a multi-component lighting intervention in hospital nurses that included 6500 K architectural lighting in the nurses’ station plus optional behavioral components (a lightbox, blueblocker glasses, eyemasks) with instruction about appropriately timed usage. Selective improvements from baseline were observed in on-shift performance, sleep quality, and caffeine consumption in day workers (all p < 0.05); off-shift sleepiness scores improved for night workers (p < 0.05). Further, self-reported measures of quality of life improved for both groups (p < 0.05). Preliminary implementation data from interviews and questionnaires suggest perceived benefits and high acceptability of the intervention.
