Desired and comfortable lighting levels increase task efficiency. When natural lighting is inadequate in a space, artificial lighting is additionally used to support the level of light. With the technological developments, the characteristics of light are being researched comprehensively and several business segments have focused on its qualitative and quantitative characteristics. These studies have increased awareness and usage of artificial lighting systems and researchers have investigated the effects of lighting on physical and psychological aspects of human in various ways. The aim of this study is to research the effects of illuminance levels of LED lighting on user visual comfort. Eighty participants from the Department of Interior Architecture of Çankaya University participated in three lighting scenarios consisting of 200 lux, 500 lux and 800 lux that are created with LED lighting. Each lighting scenario is evaluated according to six visual comfort criteria in which a reading task is performed. The results of the study indicated that LED lighting with three different illuminance levels affect visual comfort in different ways. The results are limited to the participants and questions that are attended and used in this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=illuminance%20levels" title="illuminance levels">illuminance levels</a>, <a href="https://publications.waset.org/abstracts/search?q=LED%20lighting" title=" LED lighting"> LED lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=reading%20task" title=" reading task"> reading task</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20comfort%20criteria" title=" visual comfort criteria"> visual comfort criteria</a> </p> <a href="https://publications.waset.org/abstracts/72052/effects-of-led-lighting-on-visual-comfort-with-respect-to-the-reading-task" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9571</span> Optimal Energy Consumption with Semiconductor Lamps</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pejman%20Hosseiniun">Pejman Hosseiniun</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20Shayeghi"> Rose Shayeghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Farzaneh"> Alireza Farzaneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abolghasem%20Ghasempour"> Abolghasem Ghasempour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Using LED lamps as lighting resources with new technology in designing lighting systems has been studied in this article.

However, an initial high installation cost for building the infrastructure of solar photovoltaic devices hampers a wider adoption of such technologies. This research aims to examine currently available state-of-the-art solar photovoltaic and sensory technologies, identify major obstacles, and analyze each technology to create a benchmarking metrics from the benefit-cost analysis perspective. The on-grid HPS lighting systems will serve as the baseline for this study to compare it with other lighting alternatives such as solar and sensory LED lighting systems. This research will test the validity of the research hypothesis that alternative LED lighting systems produce more favorable benefit-cost ratios and the added initial investment costs are recouped by the savings in the operation and maintenance cost. The payback period of the excess investment and projected savings over the life-cycle of the selected lighting systems will be analyzed by utilizing the concept of Net Present Value (NPV). Researchers believe that if this study validates the research hypothesis, it can promote a wider adoption of alternative lighting systems that will eventually save millions of taxpayer dollars in the long-run. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lighting%20systems" title="lighting systems">lighting systems</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20and%20solar%20PV" title=" sensory and solar PV"> sensory and solar PV</a>, <a href="https://publications.waset.org/abstracts/search?q=benefit%20cost%20analysis" title=" benefit cost analysis"> benefit cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20present%20value" title=" net present value"> net present value</a> </p> <a href="https://publications.waset.org/abstracts/28177/highway-lighting-of-the-21st-century-is-smart-but-is-it-cost-efficient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28177.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9569</span> Design of a Low Cost Programmable LED Lighting System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Abeysekera">S.

The main challenge in the design of smart lighting systems is to produce sufficient luminous flux and uniformly accurate output spectrum for sufficiently broad area. This paper outlines the programmable LED lighting system design principles of design to achieve the two aims. In this paper, a seven-channel design using low-cost discrete LEDs is presented. Optimization algorithms are used to calculate the number of required LEDs, LEDs arrangements and optimum LED separation distance. The results show the illumination uniformity for each channel. The results also show that the maximum color error is below 0.0808 on the CIE1976 chromaticity scale. In conclusion, this paper considered the simulation and design of a seven-channel programmable lighting system using low-cost discrete LEDs to produce sufficient luminous flux and uniformly accurate output spectrum for sufficiently broad area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=light%20spectrum%20control" title="light spectrum control">light spectrum control</a>, <a href="https://publications.waset.org/abstracts/search?q=LEDs" title=" LEDs"> LEDs</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20lighting" title=" smart lighting"> smart lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=programmable%20LED%20lighting%20system" title=" programmable LED lighting system"> programmable LED lighting system</a> </p> <a href="https://publications.waset.org/abstracts/78099/design-of-a-low-cost-programmable-led-lighting-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78099.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9568</span> Reducing Energy Consumption in Architectural Spaces by Optimizing Natural Light Transmission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Javid">Parisa Javid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In architecture, daylight contributes to humans' mental and physical well-being and reduces the consumption of fossil fuels. Accordingly, Iran's rich architecture has valuable achievements and experiences that should be recognized and introduced to the Iranian and international architecture communities. There are many ways to reduce energy consumption in buildings, but electricity accounts for a large part of that consumption. Lighting up spaces with natural light is a significant factor in reducing energy consumption and preventing electricity dissipation. Aside from being expensive, electric lighting systems cause excessive heat and physical injury (eyes). This study is based on library records and documents. Modern lighting systems are used to reduce energy consumption in the interior of a building to allow for optimal transmission of natural light. It discusses how to use natural light in architecture and the benefits of natural light in buildings. Solar energy can be used more efficiently, and electrical power can be saved in residential, administrative, commercial, and educational buildings by using new methods such as light tubes and mirror directors. Modern lighting systems, natural light, and reduced energy consumption are keywords for these systems, which quickly return their investment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modern%20lighting%20systems" title="modern lighting systems">modern lighting systems</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20light" title=" natural light"> natural light</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20energy%20consumption" title=" reduced energy consumption"> reduced energy consumption</a> </p> <a href="https://publications.waset.org/abstracts/150538/reducing-energy-consumption-in-architectural-spaces-by-optimizing-natural-light-transmission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150538.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9567</span> Energy Efficient Lighting in Educational Buildings through the Example of a High School in Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihan%20Gurel%20Ulusan">Nihan Gurel Ulusan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is obvious that electrical energy, which is an inseparable part of modern day’s human and also the most important power source of our age, should be generated on a level that will suffice the nation’s requirements. The electrical energy used for a sustainable architectural design should be reduced as much as possible. Designing the buildings as energy efficient systems which aim at reducing the artificial illumination loads has been a current subject of our times as a result of concepts gaining importance like conscious consumption of energy sources, environment-friendly designs and sustainability. Reducing the consumption of electrical energy regarding the artificial lighting carries great significance, especially in the volumes which are used all day long like the educational buildings. Starting out with such an aim in this paper, the educational buildings are explored in terms of energy efficient lighting. Firstly, illumination techniques, illumination systems, light sources, luminaries, illumination controls and 'efficient energy' usage in lighting are mentioned. In addition, natural and artificial lighting systems used in educational buildings and also the spaces building up these kind buildings are examined in terms of energy efficient lighting. Lastly, the illumination properties of the school sample chosen for this study, Kağıthane Anadolu Lisesi, a typical high school in Istanbul, is observed. Suggestions are made in order to improve the system by evaluating the illumination properties of the classes with the survey carried out with the users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20buildings" title="educational buildings">educational buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficient" title=" energy efficient"> energy efficient</a>, <a href="https://publications.waset.org/abstracts/search?q=illumination%20techniques" title=" illumination techniques"> illumination techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting" title=" lighting"> lighting</a> </p> <a href="https://publications.waset.org/abstracts/64601/energy-efficient-lighting-in-educational-buildings-through-the-example-of-a-high-school-in-istanbul" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64601.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">281</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9566</span> Hybrid Dynamic Approach to Optimize the Impact of Shading Design and Control on Electrical Energy Demand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Parhizkar">T.

Moreover, the combination of motorized shades with lighting systems and PV panels can lead to considerable reduction in the energy demand of buildings. In this paper, a model is developed to assess and find an optimum combination from shade designs, lighting control systems (dimming and on/off) and implementing PV panels in shades point of view. It is worth mentioning that annual saving for all designs is obtained during hourly simulation of lighting, solar heat flux and electricity generation with the use of PV panel. From 12 designs in general, three designs, two lighting control systems and PV panel option is implemented for a case study. The results illustrate that the optimum combination causes a saving potential of 792kW.hr per year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=motorized%20shades" title="motorized shades">motorized shades</a>, <a href="https://publications.waset.org/abstracts/search?q=daylight" title=" daylight"> daylight</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20load" title=" cooling load"> cooling load</a>, <a href="https://publications.waset.org/abstracts/search?q=shade%20control" title=" shade control"> shade control</a>, <a href="https://publications.waset.org/abstracts/search?q=hourly%20simulation" title=" hourly simulation"> hourly simulation</a> </p> <a href="https://publications.waset.org/abstracts/81507/hybrid-dynamic-approach-to-optimize-the-impact-of-shading-design-and-control-on-electrical-energy-demand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81507.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9565</span> Measurement and Evaluation of Outdoor Lighting Environment at Night in Residential Community in China: A Case Study of Hangzhou</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiantao%20Weng">Jiantao Weng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujie%20Zhao"> Yujie Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the improvement of living quality and demand for nighttime activities in China, the current situation of outdoor lighting environment at night needs to be assessed. Lighting environment at night plays an important role to guarantee night safety. Two typical residential communities in Hangzhou were selected. A comprehensive test method of outdoor lighting environment at night was established. The road, fitness area, landscape, playground and entrance were included. Field measurements and questionnaires were conducted in these two residential communities. The characteristics of residents’ habits and the subjective evaluation on different aspects of outdoor lighting environment at night were collected via questionnaire. A safety evaluation system on the outdoor lighting environment at night in the residential community was established. The results show that there is a big difference in illumination in different areas. The lighting uniformities of roads cannot meet the requirement of lighting standard in China. Residents pay more attention to the lighting environment of the fitness area and road than others.

This paper focuses on such sustainable solutions to lighting, which will have a major positive impact on the environment in the coming future. A questionnaire survey was conducted to note the responses of people living in high-rise buildings in metropolitan cities with regards to such sustainable lighting choices in their homes. The result of such questionnaire survey has helped to design parameters which are used to ideate design interventions in this field of sustainable lighting choices. This paper includes proposals to facilitate the reduction of electric power in interior lighting through various lighting accessory design interventions. Thus, such design interventions will allow us to design more sustainable interior spaces, and renewable energy strategies can be developed in the field of lighting, which will not only help to save energy but also positively affect other aspects of human well-being such as productivity, heritage conservation and economic well-being too! <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable" title="sustainable">sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=interior%20lighting" title=" interior lighting"> interior lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting%20design" title=" lighting design"> lighting design</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title=" environmental impact"> environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=metropolitan%20cities" title=" metropolitan cities"> metropolitan cities</a> </p> <a href="https://publications.waset.org/abstracts/140576/sustainable-lighting-solutions-in-residential-interiors-to-combat-the-ever-growing-problem-of-environmental-degradation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140576.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">205</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9563</span> The Performance of Natural Light by Roof Systems in Cultural Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Esteves">Ana Paula Esteves</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20S.%20Caetano"> Diego S.

The roofs, as a part of contact between the building and the external environment, require special attention in projects that aim at energy efficiency, being an important element for the capture of natural light in greater quantity, but also for being the most important point of generation of photovoltaic solar energy, even semitransparent, allowing the partial passage of light. Transparent elements in roofs, as well as superior protection of the building, can also play other roles, such as: meeting the needs of natural light for the accomplishment of the internal tasks, attending to the visual comfort; to bring benefits to the human perception and about the interior experience in a building. When these resources are well dimensioned, they also contribute to the energy efficiency and consequent character of sustainability of the building. Therefore, when properly designed and executed, a roof light system can bring higher quality natural light to the interior of the building, which is related to the human health and well-being dimension. Furthermore, it can meet the technologic, economic and environmental yearnings, making possible the more efficient use of that primordial resource, which is the light of the Sun. The article presents the analysis of buildings that used zenith light systems in search of better lighting performance in museums and foundations: the Solomon R. Guggenheim Museum in the United States, the Iberê Camargo Foundation in Brazil, the Museum of Fine Arts in Castellón in Spain and the Pinacoteca of São Paulo. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20lighting" title="natural lighting">natural lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=roof%20lighting%20systems" title=" roof lighting systems"> roof lighting systems</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20lighting%20in%20museums" title=" natural lighting in museums"> natural lighting in museums</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort%20lighting" title=" comfort lighting"> comfort lighting</a> </p> <a href="https://publications.waset.org/abstracts/83267/the-performance-of-natural-light-by-roof-systems-in-cultural-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83267.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9562</span> Lighting Consumption Analysis in Retail Industry: Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20C.%20Tama%C5%9F">Elena C.

Some buildings have installed building management systems (BMS) to monitor also the lighting performances starting with the opening days till the present days but some have chosen only local meters to implement. Firstly, for each analyzed building, the total required energy power and the energy power consumption for lighting were calculated depending on the lamps number, the unit power and the average daily running hours. All objects and installations were chosen depending on the destination/location of the lighting (exterior parking or access, interior or covering parking, building interior and building perimeter). Secondly, to all lighting objects and installations, mechanical counters were installed, and to the ones linked to BMS there were installed the digital meters as well for a better monitoring. Some efficient solutions are proposed to improve the power consumption, for example the 1/3 lighting functioning for the covered and exterior parking lighting to those buildings if can be done. This type of lighting share can be performed on each level, especially on the night shifts. Another example is to use the dimmers to reduce the light level, depending on the executed work in the respective area, and a 30% power energy saving can be achieved. Using the right BMS to monitor, the energy consumption depending on the average operational daily hours and changing the non-performant unit lights with the ones having LED technology or economical ones might increase significantly the energy performances and reduce the energy consumption of the buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=commercial%20buildings" title="commercial buildings">commercial buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20performances" title=" energy performances"> energy performances</a>, <a href="https://publications.waset.org/abstracts/search?q=lightning%20consumption" title=" lightning consumption"> lightning consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a> </p> <a href="https://publications.waset.org/abstracts/87454/lighting-consumption-analysis-in-retail-industry-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9561</span> The Effect of Irradiation Distance on Microhardness of Hybrid Resin Composite Polymerization Using Light-Emitting Diodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deli%20Mona">Deli Mona</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafika%20Husni"> Rafika Husni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this research is to evaluate the effect of lighting distance on surface hardness of light composite resin.

However, colour perception is also affected by the correlated colour temperature (CCT) of a light source which is considered as one of the most fundamental quantitative lighting characteristics. This study focuses on evaluating colour perception in different CCT of light emitting diodes (LED) lighting. The aim is to compare the inherent colours with the perceived colours under two CCT of ‘warm’ (2700K), and ‘cool’ (4000K) LED lights and to understand how different CTT affect the perception of a colour. Analysis and specifications of colour attributes are made with Natural Colour System (NCS) which is an international colour communication system. The outcome of the study reveals the possible tendencies for perceived colours under different illuminance levels of LED lighting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colour%20perception" title="colour perception">colour perception</a>, <a href="https://publications.waset.org/abstracts/search?q=correlated%20colour%20temperature" title=" correlated colour temperature"> correlated colour temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=inherent%20and%20perceived%20colour" title=" inherent and perceived colour"> inherent and perceived colour</a>, <a href="https://publications.waset.org/abstracts/search?q=LED%20lighting" title=" LED lighting"> LED lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20colour%20system%20%28NCS%29" title=" natural colour system (NCS)"> natural colour system (NCS)</a> </p> <a href="https://publications.waset.org/abstracts/73007/evaluation-of-colour-perception-in-different-correlated-colour-temperature-of-led-lighting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73007.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9559</span> The Importance of Zenithal Lighting Systems for Natural Light Gains and for Local Energy Generation in Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Esteves">Ana Paula Esteves</a>, <a href="https://publications.waset.org/abstracts/search?q=Diego%20S.%20Caetano"> Diego S.

Understanding that sustainability needs to cover several aspects, a roofing system such as zenithal lighting system can contribute to the provision of better quality natural light for the interior of the building, which is related to the good health and welfare; it will also be able to contribute for the sustainable aspects and environmental needs, when it allows the generation of energy in semitransparent or opacity photovoltaic solutions and economize the artificial lightning. When the energy balance in the building is positive, that is, when the building generates more energy than it consumes, it may fit into the Net Zero Energy Building concept. The zenithal lighting systems could be an important ally in Brazil, when solved the burden of heat gains, participate in the set of pro-efficiency actions in search of "zero energy buildings". The paper presents comparative three cases of buildings that have used this feature in search of better environmental performance, both in light comfort and sustainability as a whole. Two of these buildings are examples in Europe: the Notley Green School in the UK and the Isofóton factory in Spain. The third building with these principles of shed´s roof is located in Brazil: the Ipel´s factory in São Paulo. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20lighting" title="natural lighting">natural lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20zero%20energy%20building" title=" net zero energy building"> net zero energy building</a>, <a href="https://publications.waset.org/abstracts/search?q=sheds" title=" sheds"> sheds</a>, <a href="https://publications.waset.org/abstracts/search?q=semi-transparent%20photovoltaics" title=" semi-transparent photovoltaics"> semi-transparent photovoltaics</a> </p> <a href="https://publications.waset.org/abstracts/83206/the-importance-of-zenithal-lighting-systems-for-natural-light-gains-and-for-local-energy-generation-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83206.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9558</span> The Effect of Blue Lighting on Feeding Behaviour, Growth, and Corticosterone of Broiler Chickens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Harimurti">Sri Harimurti</a>, <a href="https://publications.waset.org/abstracts/search?q=Diah%20Reni%20Asih"> Diah Reni Asih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was designated to investigate the effect of intermittent and continuous blue lighting on the feeding behaviour, growth and corticosterone hormone concentration of broiler.

In addition, the paper includes a wide variety of important and relevant safety and health parameters. In modern, computerized work in the cab of forest machines, artificial illumination is a demanding task when performing duties, such as the visual inspections of wood and computer calculations. We interviewed entrepreneurs and gathered the following as the most pertinent themes: (1) safety, (2) practical problems, and (3) work with LED lighting. The most important comments were in regards to the practical problems of LED lighting. We found indications of technical problems in implementing LED lighting, like snow and dirt on the surfaces of lamps that dim the emission of light. Moreover, service work in the dark forest is dangerous and increases the risks of on-site accidents. We also concluded that the amount of blue light to the eyes should be assessed, especially, when the drivers are working in a semi-dark cab. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest%20machines" title="forest machines">forest machines</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=LED" title=" LED"> LED</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety "> safety </a> </p> <a href="https://publications.waset.org/abstracts/35492/led-lighting-interviews-and-assessment-in-forest-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35492.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9556</span> Domestic Led Lighting Designs Using Internet of Things</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gouresh%20Singhal">Gouresh Singhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajib%20Kumar%20Panigrahi"> Rajib Kumar Panigrahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we try to examine historical and technological changes in lighting industry.

The primary objective of this paper is to identify the major problems encountered in mine lighting application and to provide guidance in the solution of these problems. In the surface mining reflectance of surrounding surfaces is one of the important factors, which improve the vision, in the night hours. But due to typical working nature in the mines it is very difficult to fulfill these requirements, and also the orientation of the light at work site is a challenging task. Due to this reason machine operator and other workers in a mine need to be able to orient themselves in a difficult visual environment. The haul roads always keep on changing to tune with the mining activity. Other critical area such as dumpyards, stackyards etc. also change their phase with time, and it is difficult to illuminate such areas. Mining is a hazardous occupation, with workers exposed to adverse conditions; apart from the need for hard physical labor, there is exposure to stress and environmental pollutants like dust, noise, heat, vibration, poor illumination, radiation, etc. Visibility is restricted when operating load haul dumper and Heavy Earth Moving Machinery (HEMM) vehicles resulting in a number of serious accidents. one of the leading causes of these accidents is the inability of the equipment operator to see clearly people, objects or hazards around the machine. Results indicate blind spots are caused primarily by posts, the back of the operator's cab, and by lights and light brackets. The careful designed and implemented, lighting systems provide mine workers improved visibility and contribute to improved safety, productivity and morale. Properly designed lighting systems can improve visibility and safety during working in the opencast mines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contrast" title="contrast">contrast</a>, <a href="https://publications.waset.org/abstracts/search?q=efficacy" title=" efficacy"> efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=illuminance" title=" illuminance"> illuminance</a>, <a href="https://publications.waset.org/abstracts/search?q=illumination" title=" illumination"> illumination</a>, <a href="https://publications.waset.org/abstracts/search?q=light" title=" light"> light</a>, <a href="https://publications.waset.org/abstracts/search?q=luminaire" title=" luminaire"> luminaire</a>, <a href="https://publications.waset.org/abstracts/search?q=luminance" title=" luminance"> luminance</a>, <a href="https://publications.waset.org/abstracts/search?q=reflectance" title=" reflectance"> reflectance</a>, <a href="https://publications.waset.org/abstracts/search?q=visibility" title=" visibility"> visibility</a> </p> <a href="https://publications.waset.org/abstracts/20531/factors-affecting-visual-environment-in-mine-lighting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20531.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9552</span> The Effect of Power of Isolation Transformer on the Lamps in Airfield Ground Lighting Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Edrisi">Hossein Edrisi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To study the impact of the amount and volume of power of isolation transformer on the lamps in airfield Ground Lighting Systems. A test was conducted in Persian Gulf International Airport, This airport is situated in the south of Iran and it is one of the most cutting-edge airports, the same one that owns modern devices. Iran uses materials and auxiliary equipment which are made by ADB Company from Belgium. Airfield ground lighting (AGL) systems are responsible for providing visual issue to aircrafts and helicopters in the runways. In an AGL system a great deal of lamps are connected in serial circuits to each other and each ring has its individual constant current regulators (CCR), which through that provide energy to the lamps. Control of lamps is crucial for maintenance and operation in the AGL systems. Thanks to the Programmable Logic Controller (PLC) that is a cutting-edge technology can help the system to connect the elements from substations and ATC (TOWER). For this purpose, a test in real conditions of the airport done for all element that used in the airport such as isolation transformer in different power capacity and different consuming power and brightness of the lamps. The data were analyzed with Lux meter and Multimeter. The results had shown that the increase in the power of transformer caused a significant increase in brightness. According to the Ohm’s law and voltage division, without changing the characteristics of the light bulb, it is not possible to change the voltage, just need to change the amount of transformer with which it connects to the lamps. When the voltage is increased, the current through the bulb has to increase as well, because of Ohm's law: I=V/R and I=V/R which means that if V increases, so do I increase. The output voltage on the constant current regulator emerges between the lamps and the transformers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGL" title="AGL">AGL</a>, <a href="https://publications.waset.org/abstracts/search?q=CCR" title=" CCR"> CCR</a>, <a href="https://publications.waset.org/abstracts/search?q=lamps" title=" lamps"> lamps</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=Ohm%E2%80%99s%20law" title=" Ohm’s law"> Ohm’s law</a> </p> <a href="https://publications.waset.org/abstracts/73064/the-effect-of-power-of-isolation-transformer-on-the-lamps-in-airfield-ground-lighting-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73064.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9551</span> Design of Smart Urban Lighting by Using Social Sustainability Approach </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Noroozi">Mohsen Noroozi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Khalili"> Maryam Khalili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Creating cities, objects and spaces that are economically, environmentally and socially sustainable and which meet the challenge of social interaction and generation change will be one of the biggest tasks of designers. Social sustainability is about how individuals, communities and societies live with each other and set out to achieve the objectives of development model which they have chosen for themselves. Urban lightning as one of the most important elements of urban furniture that people constantly interact with it in public spaces; can be a significant object for designers. Using intelligence by internet of things for urban lighting makes it more interactive in public environments. It can encourage individuals to carry out appropriate behaviors and provides them the social awareness through new interactions. The greatest strength of this technology is its strong impact on many aspects of everyday life and users' behaviors. The analytical phase of the research is based on a multiple method survey strategy. Smart lighting proposed in this paper is an urban lighting designed on results obtained from a collective point of view about the social sustainability. In this paper, referring to behavioral design methods, the social behaviors of the people has been studied. Data show that people demands for a deeper experience of social participation, safety perception and energy saving with the meaningful use of interactive and colourful lighting effects. By using intelligent technology, some suggestions are provided in the field of future lighting to consider the new forms of social sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavior%20pattern" title="behavior pattern">behavior pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability" title=" social sustainability"> social sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20lighting" title=" urban lighting"> urban lighting</a> </p> <a href="https://publications.waset.org/abstracts/91204/design-of-smart-urban-lighting-by-using-social-sustainability-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91204.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9550</span> The Effects of Lighting Environments on the Perception and Psychology of Consumers of Different Genders in a 3C Retail Store</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Fong%20Lin">Yu-Fong Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this study is to explore the impact of different lighting arrangements that create different visual environments in a 3C retail store on the perception, psychology, and shopping tendencies of consumers of different genders. In recent years, the ‘emotional shopping’ model has been widely accepted in the consumer market; in addition to the emotional meaning and value of a product, the in-store ‘shopping atmosphere’ has also been increasingly regarded as significant. The lighting serves as an important environmental stimulus that influences the atmosphere of a store. Altering the lighting can change the color, the shape, and the atmosphere of a space. A successful retail lighting design can not only attract consumers’ attention and generate their interest in various goods, but it can also affect consumers’ shopping approach, behavior, and desires. 3C electronic products have become mainstream in the current consumer market. Consumers of different genders may demonstrate different behaviors and preferences within a 3C store environment. This study tests the impact of a combination of lighting contrasts and color temperatures in a 3C retail store on the visual perception and psychological reactions of consumers of different genders. The research design employs an experimental method to collect data from subjects and then uses statistical analysis adhering to a 2 x 2 x 2 factorial design to identify the influences of different lighting environments. This study utilizes virtual reality technology as the primary method by which to create four virtual store lighting environments. The four lighting conditions are as follows: high contrast/cool tone, high contrast/warm tone, low contrast/cool tone, and low contrast/warm tone. Differences in the virtual lighting and the environment are used to test subjects’ visual perceptions, emotional reactions, store satisfaction, approach-avoidance intentions, and spatial atmosphere preferences. The findings of our preliminary test indicate that female subjects have a higher pleasure response than male subjects in a 3C retail store. Based on the findings of our preliminary test, the researchers modified the contents of the questionnaires and the virtual 3C retail environment with different lighting conditions in order to conduct the final experiment. The results will provide information about the effects of retail lighting on the environmental psychology and the psychological reactions of consumers of different genders in a 3C retail store lighting environment. These results will enable useful practical guidelines about creating 3C retail store lighting and atmosphere for retailers and interior designers to be established. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3C%20retail%20store" title="3C retail store">3C retail store</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20stimuli" title=" environmental stimuli"> environmental stimuli</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting" title=" lighting"> lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a> </p> <a href="https://publications.waset.org/abstracts/45160/the-effects-of-lighting-environments-on-the-perception-and-psychology-of-consumers-of-different-genders-in-a-3c-retail-store" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45160.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9549</span> Effect of Architecture and Operating Conditions of Vehicle on Bulb Lifetime in Automotive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatice%20%C3%96zbek">Hatice Özbek</a>, <a href="https://publications.waset.org/abstracts/search?q=Caner%20%C3%87il"> Caner Çil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Rodoplu"> Ahmet Rodoplu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automotive lighting is the leading function in the configuration of vehicle architecture. Especially headlights and taillights from external lighting functions are among the structures that determine the stylistic character of the vehicle. At the same time, the fact that lighting functions are related to many other functions brings along difficulties in design. Customers expect maximum quality from the vehicle. In these circumstances, it is necessary to make designs that aim to keep the performance of bulbs with limited working lives at the highest level. With this study, the factors that influence the working lives of filament lamps were examined and bulb explosions that can occur sooner than anticipated in the future were prevented while the vehicle was still in the design phase by determining the relations with electrical, dynamical and static variables. Especially the filaments of the bulbs used in the front lighting of the vehicle are deformed in a shorter time due to the high voltage requirement. In addition to this, rear lighting lamps vibrate as a result of the tailgate opening and closing and cause the filaments to be exposed to high stress. With this study, the findings that cause bulb explosions were evaluated. Among the most important findings: 1. The structure of the cables to the lighting functions of the vehicle and the effect of the voltage values are drawn; 2. The effect of the vibration to bulb throughout the life of the vehicle; 3 The effect of the loads carried to bulb while the vehicle doors are opened and closed. At the end of the study, the maximum performance was established in the bulb lifetimes with the optimum changes made in the vehicle architecture based on the findings obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle%20architecture" title="vehicle architecture">vehicle architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=automotive%20lighting%20functions" title=" automotive lighting functions"> automotive lighting functions</a>, <a href="https://publications.waset.org/abstracts/search?q=filament%20lamps" title=" filament lamps"> filament lamps</a>, <a href="https://publications.waset.org/abstracts/search?q=bulb%20lifetime" title=" bulb lifetime"> bulb lifetime</a> </p> <a href="https://publications.waset.org/abstracts/107957/effect-of-architecture-and-operating-conditions-of-vehicle-on-bulb-lifetime-in-automotive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107957.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9548</span> Research on Natural Lighting Design of Atriums Based on Energy-Saving Aim</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fan%20Yu">Fan Yu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An atrium is a place for natural climate exchanging of indoor and outdoor space of buildings, which plays an active role in the overall energy conservation, climate control and environmental purification of buildings. Its greatest contribution is serving as a natural light collector and distributor to solve the problem of natural lighting in large and deep spaces. However, in real situations, the atrium space often results in energy consumption due to improper design in considering its big size and large amount use of glass. Based on the purpose of energy conservation of buildings, this paper emphasizes the significance of natural lighting of atriums. Through literature research, case analysis and other methods, four factors, namely: the light transmittance through the top of the atrium, the geometric proportion of the atrium space, the size and position of windows and the material of the surface of walls in the atrium, were studied, and the influence of different architectural compositions on the natural light distribution of the atrium is discussed. Relying on the analysis of relevant cases, it is proposed that when designing the natural lighting of the atrium, the height and width of the atrium should be paid attention to, the atrium walls are required being rough surfaces and the atrium top-level windows need to be minimized in order to introduce more natural light into the buildings and achieve the purpose of energy conservation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation" title="energy conservation">energy conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=atrium" title=" atrium"> atrium</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20lighting" title=" natural lighting"> natural lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20design" title=" architectural design"> architectural design</a> </p> <a href="https://publications.waset.org/abstracts/97105/research-on-natural-lighting-design-of-atriums-based-on-energy-saving-aim" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97105.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">191</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9547</span> Museums: The Roles of Lighting in Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernanda%20S.%20Oliveira">Fernanda S.

There is a growing evidence that adopting passive design solutions may contribute to higher satisfaction. This is even more important in countries with higher solar radiation, which should take advantage of favourable daylighting conditions. However, in art museums, the same light that stimulates vision can also cause permanent damage to the exhibits. Not only the visitors want to see the objects, but also to understand their nature and the artist’s intentions. This paper examines the hypothesis that the more varied and exciting the lighting (and particularly the daylight) in museums rooms, over space and time, the more likely it is that visitors will stay longer, enjoy their experience and be willing to return. This question is not often considered in museums that privilege artificial lighting neglecting the various qualities of daylight other than its capacity to illuminate spaces. The findings of this paper show that daylight plays an important role in museum design, affecting how visitors perceive the exhibition space, as well as contributing to their overall enjoyment in the museum. Rooms with high luminance means were considered more pleasant (r=.311, p<.05) and cheerful (r=.349, p<.05). Lighting conditions also have a direct effect on the phenomenon of museum fatigue with the overall room quality showing an effect on how tired visitors reported to be (r=.421, p<.01). The control and distribution of daylight in museums can therefore contribute to create pleasant conditions for learning, entertainment and amusement, so that visitors are willing to return. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=daylight" title="daylight">daylight</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort" title=" comfort"> comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=museums" title=" museums"> museums</a>, <a href="https://publications.waset.org/abstracts/search?q=luminance" title=" luminance"> luminance</a>, <a href="https://publications.waset.org/abstracts/search?q=visitor" title=" visitor "> visitor </a> </p> <a href="https://publications.waset.org/abstracts/15202/museums-the-roles-of-lighting-in-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15202.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">486</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9546</span> Communication Aesthetics of Techno-Scenery and Lighting in Bolanle Austen-Peters Queen Moremi the Musical</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Badeji%20Adebayo%20John">Badeji Adebayo John</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technology has immense contribution in every aspect of human endeavor; it has not only made work easier but also provided exhilarating impression in the mind of the people. Theatre is not exempted from the multifaceted influence of technology on phenomenon. Therefore, theatre performances have experienced the excellence of technology in the contemporary era such that audiences have unforgettable experiences after seeing theatre performances. Some of these technological advancements that have amplified the aesthetics of performances in the theatre are techno-scenery (3D mapping) and lighting. In view of this, the objective of this study is to explore how techno-scenery and lighting technologies were used to communicate messages in the performance of Queen Moremi the Musical. In so doing, Participant-Observation Method and Content Analysis are adopted. Berlo’s model of communication is also employed to explain the communicative aesthetics of these theatre technologies in the performance. Techno-scenery and lighting are communication media modifier that facilitates audiences’ comprehension of the messages in the performance of Queen Moremi the Musical. They also create clear motion pictures of the setting which the performers cannot communicate in their acting, dances and singing, to ease the audiences’ decoding of messages that the performers are sending to the audience. Therefore, consistent incorporation of these technologies to theatre performances will facilitate easy flow of communication in-between the performers who are the sender, the message which is the performance and the audience who are the receiver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=aesthetics" title=" aesthetics"> aesthetics</a>, <a href="https://publications.waset.org/abstracts/search?q=techno-scenery" title=" techno-scenery"> techno-scenery</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting" title=" lighting"> lighting</a>, <a href="https://publications.waset.org/abstracts/search?q=musical" title=" musical"> musical</a> </p> <a href="https://publications.waset.org/abstracts/161566/communication-aesthetics-of-techno-scenery-and-lighting-in-bolanle-austen-peters-queen-moremi-the-musical" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161566.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9545</span> Flowering Response of a Red Pitaya Germplasm Collection to Lighting Addition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dinh-Ha%20Tran">Dinh-Ha Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Ruey%20Yen"> Chung-Ruey Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Kuang%20H.%20Chen"> Yu-Kuang H.

The night-breaking treatment was conducted during the period of 10 Oct. 2013 to 5 Mar. 2014 with 4-continuous hours (22.00–02.00 hrs) of additional lighting daily using incandescent bulbs (100W). Among cultivars and clones tested, twenty-three genotypes, most belonging to the red-magenta flesh type, were found to have positive flowering response to the lighting treatment. The duration of night-breaking treatment for successful flowering initiation varied from 33 - 48 days. The lighting-sensitive genotypes bore 1-2 flowering flushes. Floral and fruiting stages took 21-26 and 46-59 days, respectively. Among sixteen fruiting genotypes, the highest fruit set rates were found in Damao 9, D4, D13, Chaozou large, Chaozhou 5, Small Nick and F22. Five cultivars and clones (Orejona, D4, Chaozhou large, Chaozhou 5, and Small Nick) produced fruits with an average weight of more than 300 g per fruit which was higher than those of the fruits formed in the summer of 2013. Fruits produced during off-season contain total soluble solids (TSS) from 17.5 to 20.7 oBrix, which was higher than those produced in-season. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flowering%20response" title="flowering response">flowering response</a>, <a href="https://publications.waset.org/abstracts/search?q=long-day%20plant" title=" long-day plant"> long-day plant</a>, <a href="https://publications.waset.org/abstracts/search?q=night-breaking%20treatment" title=" night-breaking treatment"> night-breaking treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=off-season%20production" title=" off-season production"> off-season production</a>, <a href="https://publications.waset.org/abstracts/search?q=pitaya" title=" pitaya"> pitaya</a> </p> <a href="https://publications.waset.org/abstracts/24456/flowering-response-of-a-red-pitaya-germplasm-collection-to-lighting-addition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24456.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">302</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9544</span> Intercultural Intelligence: How to Turn Cultural Difference into a Key Added Value with Tree Lighting Design Project Examples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fanny%20Soulard">Fanny Soulard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today work environment is more multicultural than ever: spatial limits have been blown out, encouraging people and ideas mobility all around the globe. Indeed, opportunities to design with culturally diverse team workers, clients, or end-users, have become within everyone's reach. We enjoy traveling to discover other civilizations, but when it comes to business, we often take for granted that our own work methodology will be generic enough to federate each party and cover the project needs. This paper aims to explore why, by skipping cultural awareness, we often create misunderstandings, frustration, and even counterproductive design. Tree lighting projects successively developed by a French lighting studio, a Vietnamese lighting studio, and an Australian Engineering company will be assessed from their concept stage to completion. All these study cases are based in Vietnam, where the construction market is equally led by local and international consultants. Core criteria such as lighting standard reference, service scope, communication tools, internal team organization, delivery package content, key priorities, and client relationship will help to spot and list when and how cultural diversity has impacted the design output and effectiveness. On the second hand, we will demonstrate through the same selected projects how intercultural intelligence tools and mindset can not only respond positively to previous situations and avoid major clashes but also turn cultural differences into a key added value to generate significant benefits for individuals, teams, and companies. By understanding the major importance of including a cultural factor within any design, intercultural intelligence will quickly turn out as a “must have” skill to be developed and acquired by any designer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intercultural%20intelligence" title="intercultural intelligence">intercultural intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=lighting%20design" title=" lighting design"> lighting design</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20methodology" title=" work methodology"> work methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=multicultural%20diversity" title=" multicultural diversity"> multicultural diversity</a> </p> <a href="https://publications.waset.org/abstracts/162197/intercultural-intelligence-how-to-turn-cultural-difference-into-a-key-added-value-with-tree-lighting-design-project-examples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162197.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9543</span> Informing Lighting Designs Through a Comprehensive Review of Light Pollution Impacts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephen%20M.%20Simmons">Stephen M.

Much research has been conducted in order to study the effects of artificial light at night, and many adverse impacts have been discovered, such as circadian disruption, degradation of the night sky, and interference oftheprocesses and behaviors of plants and animals. Despite a plethora of informationin the literature regarding the numerous illeffects of this type of pollution, there does not appear to be a complete summary of these impacts, including their magnitudes, which would facilitate the balancing of risks and benefits in the design of an exterior lighting system. This paperprovides a comprehensive review of the known impacts of light pollution, divided into four categories - human health, night sky, plants, and animals; additionally, it includes a synopsis of what likely remains unknown at this point in time. This review will attempt to showcase the relative significance of differentimpacts within each category, as well as their sensitivity to changes in lighting specifications (brightness, color temperature, shielding, and mounting height). Methods to be employed in this research include an extensive literature review and the gathering of expert knowledge and opinions. The findings of this review will be used to inform the creation of an optimized lighting design for the Missouri University of Science and Technology campus. It is hoped that future research willexplore the known impacts of light pollution further, as well as search for what still remains to be found regarding the consequencesof artificial light at night.
