  Title Role Of Artificial Lighting In Emphasizing The Entrance Approaches Type Journal Article
  Year 2020 Publication Architecture and Planning Journal Abbreviated Journal APJ  
  Volume 26 Issue 2 Pages  
  Keywords Lighting; Architecture  
  Abstract Building's entrance is metaphorically a threshold between two realms, the first is an outdoor exposed to climatic change, hazards, and environmental factors, while the second is controlled, monitored, and determined to certain functions. It plays an important role in enriching users' experience. Moreover, it is the first impression a visitor takes to evaluate a whole building. Architecturally, the entrance is a very special part in the elevation, distinguished and emphasized by different design approaches. One of these approaches is using lighting. There is a direct connection between recognition of a space and light assimilation in it. From sunset to dawn, the artificial lighting plays a role in drawing attention to texture, colours, and forms of external elevations, which supports architecture to achieve its purpose. This paper sheds the light on the problem of architects' failure to manage an entrance perception due to insufficient light integration, over illumination, or weak transition from space to another. Many architects consider the entrance as a challenging task, because they believe that it has a direct impact on visitors' perception. This paper, therefore, aims to propose design methods to emphasize the entrance of buildings at night through using the proper artificial lighting. To achieve this aim, the paper used a scientific methodology, based on tracing literature review about design of entrances, investigating ideas of entrances' emphasis, and then analysing four case studies trying to identify the different design approaches of their entrances and how the location, direction, and intensity of illumination became a part of their nocturnal architectural elevation. As a conclusion, techniques of lighting entrances contribute in perceiving architecture’s true purpose and raise the aesthetic dimension of the building at night.

  Title Sustainable Low Carbon Urban Lighting Analysis: A Case Study of Bandung City Type Journal Article
  Year 2020 Publication Journal of Engineering Sciences Abbreviated Journal  
  Volume 7 Issue 1 Pages H9-H18  
  Keywords Energy; Lighting  
  Abstract Nowadays, lighting technology is in the transition period from conventional lighting to LED, which more environmentally friendly due to free of harmful substances such as mercury, lead, or other hazardous chemicals and gases. This low light pollution because directional light is carefully distributed precisely to the intended location. Performance of the lights also brighter than other lights. This research measuring the reduction of CO2 gas emissions before and after PJU (street lights) in Bandung is changed from the conventional to the LED, also mapping the CO2 gas emissions in six Development Areas (SWK). The basis for this research approach is a case study with before and after comparison, meaning that this approach only applies to one object that is the same as comparing the condition of the object before and after the treatment. In this study, the evaluation research method used is a causal method, which is a method that is more directed at impact evaluation research. Scientifically and objectively, PJU LED provides low CO2 emissions gas by up to 26 % in Bandung city.

  Title Advanced Adaptive Street Lighting Systems for Smart Cities Type Journal Article
  Year 2020 Publication Smart Cities Abbreviated Journal Smart Cities  
  Volume 3 Issue 4 Pages 1495-1512  
  Keywords Lighting; Energy  
  Abstract This paper reports the results of a recently concluded R&D project, SCALS (Smart Cities Adaptive Lighting System), which aimed at the development of all hardware/software components of an adaptive urban smart lighting architecture allowing municipalities to manage and control public street lighting lamps. The system is capable to autonomously adjust street lamps’ brightness on the basis of the presence of vehicles (busses/trucks, cars, motorcycles and bikes) and/or pedestrians in specific areas or segments of the streets/roads of interest to reduce the energy consumption. The main contribution of this work is to design a low cost smart lighting system and, at same time, to define an IoT infrastructure where each lighting pole is an element of a network that can increase their amplitude. More generally, the proposed smart infrastructure can be viewed as the basis of a wider technological architecture aimed at offering value-added services for sustainable cities. The smart architecture combines various sub-systems (local controllers, motion sensors, video-cameras, weather sensors) and electronic devices, each of them in charge of performing specific operations: remote street segments lamp management, single street lamp brightness control, video processing for vehicles motion detection and classification, wireless and wired data exchanges, power consumptions analysis and traffic evaluation. Two pilot sites have been built up in the project where the smart architecture has been tested and validated in real scenarios. Experimental results show that energy savings of up to 80% are possible compared to a traditional street lamp system.

  Title A linear systems approach to protect the night sky: implications for current and future regulations Type Journal Article
  Year 2020 Publication Royal Society Open Science Abbreviated Journal R. Soc. open sci.  
  Volume 7 Issue 12 Pages 201501  
  Keywords Skyglow; Regulation; Lighting  
  Abstract The persistent increase of artificial light emissions is causing a progressive brightening of the night sky in most regions of the world. This process is a threat for the long-term sustainability of the scientific and educational activity of ground-based astronomical observatories operating in the optical range. Huge investments in building, scientific and technical workforce, equipment and maintenance can be at risk if the increasing light pollution levels hinder the capability of carrying out the top-level scientific observations for which these key scientific infrastructures were built. Light pollution has other negative consequences, as e.g. biodiversity endangering and the loss of the starry sky for recreational, touristic and preservation of cultural heritage. The traditional light pollution mitigation approach is based on imposing conditions on the photometry of individual sources, but the aggregated effects of all sources in the territory surrounding the observatories are seldom addressed in the regulations. We propose that this approach shall be complemented with a top-down, ambient artificial skyglow immission limits strategy, whereby clear limits are established to the admissible deterioration of the night sky above the observatories. We describe the general form of the indicators that can be employed to this end, and develop linear models relating their values to the artificial emissions across the territory. This approach can be easily applied to other protection needs, like e.g. to protect nocturnal ecosystems, and it is expected to be useful for making informed decisions on public lighting, in the context of wider spatial planning projects.

  Title Outdoor light at night and breast cancer incidence in the Danish Nurse Cohort Type Journal Article
  Year 2020 Publication Environmental Research Abbreviated Journal Environ Res  
  Volume 194 Issue Pages 110631  
  Keywords Human health; Remote sensing; Breast neoplasms; Environmental exposure; Female; Incidence; Lighting; Middle-aged; Prospective studies; Risk factors  
  Abstract BACKGROUND: Knowledge of the role of melatonin, xenograft experiments, and epidemiological studies suggests that exposure to light at night (LAN) may disturb circadian rhythms, possibly increasing the risk of developing breast cancer. OBJECTIVES: We examined the association between residential outdoor LAN and the incidence of breast cancer: overall and subtypes classified by estrogen (ER) and progesterone (PR) receptor status. METHODS: We used data on 16,941 nurses from the Danish Nurse Cohort who were followed-up from the cohort baseline in 1993 or 1999 through 2012 in the Danish Cancer Registry for breast cancer incidence and the Danish Breast Cancer Cooperative Group for breast cancer ER and PR status. LAN exposure data were obtained from the U.S. Defense Meteorological Satellite Program (DMSP) available for 1996, 1999, 2000, 2003, 2004, 2006, and 2010 in nW/cm(2)/sr unit, and assigned to the study participants' residence addresses during the follow-up. Time-varying Cox regression models were used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between LAN and breast cancer, adjusting for individual characteristics, road traffic noise, and air pollution. RESULTS: Of 16,941 nurses, 745 developed breast cancer in total during 320,289 person-years of follow-up. We found no association between exposure to LAN and overall breast cancer. In the fully adjusted models, HRs for the highest (65.8-446.4 nW/cm(2)/sr) and medium (22.0-65.7 nW/cm(2)/sr) LAN tertiles were 0.97 (95% CI: 0.77, 1.23) and 1.09 (95% CI: 0.90, 1.31), respectively, compared to the lowest tertile of LAN exposure (0-21.9 nW/cm(2)/sr). We found a suggestive association between LAN and ER-breast cancer. CONCLUSION: This large cohort study of Danish female nurses suggests weak evidence of the association between LAN and breast cancer incidence.
