“…IF and NIF systems demonstrate different responses to various light parameters such as quantity, spectrum, time and duration of impulses (for further details refer to Parsaee et al 10 , Refinetti 16 , DiLaura et al 18 , CIE 20 , Khademagha et al 29 , Berman and Clear 30 , Khademagha et al 31 ). Occupants' IF and NIF responses/requirements are different regarding hourly/seasonally photoperiods and different activities in the building [32][33][34] . A proper intensity and chromaticity of light at the right time must be provided to occupants 20,35 .…”

This paper develops an integrated design framework of adaptive building façades (ABFs) to respond to photobiological and thermal needs of occupants, biophilic factors, energy requirements and climatic features in Northern Canada, i.e. near and above 50°N. The paper discusses the importance of biophilic and photobiological factors and ABFs to improve occupants’ health and human–nature relations and deal with the extreme climate in Northern Canada where non-adapted buildings that could negatively affect occupants’ well-being. The paper shows that existing ABFs must be further developed for northern applications in terms of (i) the physical structure and configuration of components, (ii) the design of solar shading/louver panels to address photobiological and biophilic requirements, (iii) the development of lighting adaptation scenarios to respond to biophilic and photobiological needs, local photoperiods and energy issues and (iv) the overall biophilic quality for accessibility to natural patterns. The ABFs’ framework was developed in three phases including: (1) process environmental data, (2) produce adaptation scenarios and (3) operate adaptation scenarios. The research discussed major issues of all phases that must be further studied, especially the development of hourly/daily/seasonally lighting adaptation scenarios. The paper develops a holistic parametric methodology to integrate and optimize major design variables of ABF’s components.

“…sichtigen, wird diese Tatsache dadurch erschwert, dass Leuchten derzeit vorwiegend in Gruppen geschaltet werden [38] und größere Raumbereiche und damit mehrere Arbeitsplätze in einem Büro ausleuchten. Die Umsetzung individueller Lichtbedingungen unterliegt konzep tionellen Beschränkungen als auch Beschränkungen hinsichtlich der technischen Auslegung von Beleuchtungsanlagen [39].…”

Die Bedeutung von Nutzerzentrierung in automatisierten Beleuchtungssystemen

Derzeitig erwerbbare Beleuchtungssteuerungen versuchen Anforderungen allgemeiner Nutzerkomfortkriterien wie die normative Mindestbeleuchtungsstärke mittels Allgemeinbeleuchtungen und vordefinierten Kontrollkurven gerecht zu werden. Da diese Lösungen sowohl individuelle Nutzeranforderungen als auch Effekte, die sich aus spezifischen Arbeitsanforderungen ableiten lassen, weitestgehend vernachlässigen, können Akzeptanzraten von Nutzern signifikant in Mitleidenschaft gezogen werden. Darauf zurückzuführende Nutzereingriffe in automatisierte Steuerungen können intendierte Systemperformanzen sowohl in energetischer Hinsicht als auch in der biologischen Wirksamkeit beschränken. Um dem entgegenzuwirken, müssen Nutzerindividualitäten in die Steuerungslogik zurückgeführt werden. Prämisse einer erfolgreichen Umsetzung ist die Differenzierung von Raumausleuchtung und bedarfsorientierter Arbeitsplatzbeleuchtung. Positive Folge dieser Differenzierung ist eine Reduzierung des Energiebedarfs. Im Folgenden berichten die Autoren von ersten Ergebnissen einer Langzeitstudie in einem Großraumbüro mit zonaler Einzelarbeitsplatzbeleuchtung unter realen Arbeitsbedingungen. Die Ergebnisse der Studie führen auf, dass durch geeignete Zonierung der Energiebedarf für Kunstlicht reduziert werden kann. Darüber hinaus konnte über Langzeit‐Monitoring herausgefunden werden, dass Nutzereingriffen, die sich negativ auf den Energiebedarf auswirken, über erweiterte Inbetriebnahmephasen entgegengewirkt werden kann.

“…In addition, Guo et al [26] proposed a telemanagement road lighting control system to increase energy efficiency and this system automatically reacts to traffic density, weather conditions and so on. Dikel et al [27] suggested an energy-efficient lighting control technique according to an occupancy algorithm in an interior space and they conducted a usability test of their suggested system before demonstrating the acceptability people in a test bed. Moreover, Park et al [28] proposed a micro-distributed ESS-based smart LED streetlight system with low-cost installation and high management efficiency based on a simulation test and analysis of scenarios.…”

Design of a Connected Security Lighting System for Pedestrian Safety in Smart Cities

et al. 2019

Historical and ongoing pedestrian anxiety about night crimes in alleyways is an important issue in our society. Therefore, recommended illuminance levels in pedestrian alleys have been established and security lighting meeting such illuminance levels has been installed to ensure proper brightness. However, pedestrians may still feel that such areas are too dark and want to ensure their safety through sufficient brightness, especially late at night. In this study, a smart security lighting system, which was namely the Connected Security Lighting System (CSLS), has been designed to reduce the pedestrians’ fear of crime in smart cities. The CSLS increases the brightness of security lighting by turning on additional lights to relax pedestrians’ psychological fear of crime because of the increased sense of surveillance. Such a change may also deter potential offenders. The CSLS employs various sensors and information communication technologies that are widely used in interior and outdoor smart lighting applications. It also uses a beacon device and smartphone application to effectively detect pedestrians while infrared sensors in the CSLS are activated to detect any pedestrians approaching from the opposite direction after the beacon device is initiated. The method for controlling the CSLS is described and a prototype system is presented to demonstrate the feasibility of this security lighting system in smart cities.
