"This comprehensive guide explains how to plan and implement lighting retrofits to increase energy efficiency and improve the quality of visual performance. Lighting Retrofit Manual begins by outlining the benefits of retrofitting, then discusses when retrofits make sense, the entire retrofit process--from the data collection phase to maintenance--and explains the latest retrofit technologies and lighting system types. This reference is sure to be used by any professional or student that will deal with a lighting retrofit project--whether as a designer, installer, manager, manufacturer, or consultant"--

The present paper reviews the role of illumination in shaping the indoor environment of the elderly person. The approach is that lighting has a twofold impact on the individual. One is as a source of information about the environment, i.e., visual, and the other is photobiological through the skin or photoreceptor.The visually lighted environment is reviewed, discussing first the physiological changes that occur during the aging process, then the effect of aging on visual performance, and finally the importance of qualitative factors in assessing the adequacy of an illuminated environment for the elderly. Special attention is given to application problems in lighting for the elderly, i.e., excessive brightness differences, discomfort glare, veiling reflections, and the importance of color and the spectral power distribution of the light source. The advantages of a full-spectrum light source which simulates natural sunlight for indoor illumination is discussed in light of recent research.The biologically lighted environment is reviewed in terms of the potential role that indoor illumination can play in regulating important biochemical processes in the elderly population, i.e., neuroendocrine control, vitamin D3synthesis, immunologic mechanisms, and cardiovascular regulation.

Without light, interior architecture cannot be fully designed and experienced. It is one of the key tools for an interior designer, but can be a dauntingly technical subject for students.Part One, Theory, looks at the physics and technology behind lighting. Part Two, Process and Practice, looks more specifically at the use of lighting in interior design and outlines the key design issues and principles. The book goes on to show the ways of representing lighting schemes using CAD and 3D models and how to implement and test these designs. Finally, the book explains how to deal with contractors

Encompassing a thorough survey of the lighting techniques applied to internal illumination characterized by high efficiency, optimized color and architectural integration, a consolidated summary of the latest scientific, technical and architectural research is presented in order to give the reader an overview of the different themes with their interactions and mutual effects. This book describes light principles, methodologies and realisations for indoor illumination at low consumption. Power efficiency, color characteristics and architectural aspects are analyzed in terms of their practical application, with the interactions between scientific, technological and architectural features considered in order to supply a complete overview, which can be read both at technical level and at user level. Introducing photometric and radiometric quantities and laws, the book first discusses tests and measurements assessing lighting and color characteristics before examining in detail artificial light sources with particular attention paid to measures to reduce consumption and optimize efficiency. Key sources are illustrated with producers and suppliers with technical details and use specifications included. Serving to maximize reader insights into the use of sunlight - considering light transfer, application to indoor illumination and in particular to museum lighting - in the color rendering properties of light sources and the architectural aspects for natural indoor lighting, the final part of this boo collects other related but important elements including architectural issues, environmental integration and the possibility of changing the light color by introducing suitable coatings. The physiological effects of internal illumination quality on user comfort is discussed and several possibilities for energy saving using domotics are outlined.

Lighting Vanuatu began in 2010 as a two-year project funded through The Australian Aid - Governance for Growth Programme. The primary objective of the project was to increase access of portable solar lanterns for rural Vanuatu communities in an effort to reduce their dependency on kerosene as the primary source of household lighting. To achieve this goal the project offered a supply-side subsidy for two Vanuatu NGOs (ACTIV and VANREPA) to support the distribution of 24, 000 solar lamps mainly to rural areas. The subsidy was aimed at improving bulk purchasing power by the NGO's in an effort to reduce the price of the imported solar lights at the household level. The analysis of the Independent Completion Review (ICR), Business Case Study (Annex 1), and the Survey Data Overview (Annex 3) indicate that the Lighting Vanuatu project has been successful in enabling the uptake and awareness of portable solar lighting products. These reports highlight that the transition from kerosene lamps to solar throughout the islands of Vanuatu was both clear and ubiquitous. When framed at this descriptive level, the project certainly presents a good news story for renewable energy. The rapid transformation from a non-renewable to a renewable source of lighting within a 2 to 3 year period runs counter to many of the discussions in developed countries who struggle to disrupt the locked-in energy systems that sustain and maintain a reliance on fossil fuels. Considered alongside the slow and politically infused renewable energy debates in the developed country context, Vanuatu's rapid adoption of portable solar lighting is precisely the kind of transitional story that many communities could only dream of achieving. However, the successful or unsuccessful acquisition and diffusion of a particular piece of technology – portable solar lamps – is only part of the story. The initial aim of the Independent Completion Review (ICR) was to identify the degree of adoption and contribution made by Lighting Vanuatu, any geographic, social or cultural trends evident in adoption patterns, any economic or social benefits, specific changes in the lighting technology used by households, changes in household practices associated with any shift in technology, and changes in householders' perceived needs and aspirations with regard to lighting. While this descriptive analysis is essential for evaluating the success of the programme within its own terms (i.e. the ICR), the broader cultural, economic and political implications of this technological diffusion have yet to be addressed. The purpose of Annex 2, therefore, is to develop the Lighting Vanuatu story further by offering a more nuanced interpretation of the transition from kerosene to portable solar lights in rural Vanuatu communities; our emphasis and focus is different to that of the ICR, but complements and enhances the understanding of Lighting Vanuatu as an aid project. We begin by outlining the methodology used to gather and interpret the information that informs this report. We then draw on the Energy Cultures Framework (Stephenson et al., 2010) as an organising structure for describing Vanuatu's prevailing energy culture. Next, we address four key debates to emerge from the fieldwork with the hope of encouraging a reflection on the shifting social norms and practices (economic and political) that are also 'diffused' with the introduction of a new piece of material culture like the portable solar lamps. The annex concludes with a comment on the implications of this analysis for future energy-related development projects in Vanuatu.
