The lighting industry has changed dramatically over the past decade. The optical system design of legacy high-intensity discharge (HID) luminaires was restricted to the lamp, refractor, and reflector design, which had limits in the distribution of the light, controls, and adaptability. Roadway luminaires have moved beyond this design methodology to include the vast possibilities presented by solid-state lighting (SSL). At present, in the form of light emitting diodes (LED), SSL uses lower energy, reduces maintenance, improves color, and can be easily dimmed and controlled. The TRB National Cooperative Highway Research Program's NCHRP Research Report 940: Solid-State Roadway Lighting Design Guide: Volume 1: Guidance develops more comprehensive guidelines in American Association of State Highway Transportation Officials (AASHTO)-standard format for the application of roadway lighting related to the widespread adoption of SSL, and identifies gaps in knowledge where possible future research will enhance these guidelines.

The standard incandescent light bulb, which still works mainly as Thomas Edison invented it, converts more than 90% of the consumed electricity into heat. Given the availability of newer lighting technologies that convert a greater percentage of electricity into useful light, there is potential to decrease the amount of energy used for lighting in both commercial and residential applications. Although technologies such as compact fluorescent lamps (CFLs) have emerged in the past few decades and will help achieve the goal of increased energy efficiency, solid-state lighting (SSL) stands to play a large role in dramatically decreasing U.S. energy consumption for lighting. Since the publication of the 2013 National Research Council report Assessment of Advanced Solid-State Lighting, the penetration of SSL has increased dramatically, with a resulting savings in energy and costs that were foreshadowed by that study. What was not anticipated then is the dramatic dislocation and restructuring of the SSL marketplace, as cost reductions for light-emitting diode (LED) components reduced profitability for LED manufacturers. At the same time, there has been the emergence of new applications for SSL, which have the potential to create new markets and commercial opportunities for the SSL industry. Assessment of Solid-State Lighting, Phase Two discusses these aspects of changeâ€"highlighting the progress of commercialization and acceptance of SSL and reviewing the technical advances and challenges in achieving higher efficacy for LEDs and organic light-emitting diodes. This report will also discuss the recent trends in SSL manufacturing and opportunities for new applications and describe the role played by the Department of Energy (DOE) Lighting Program in the development of SSL.

Retail, restaurants, offices, hotel, residential, conference and exhibition centers, and parking are typically being built as part of one large complex. Increasing complexities occur as more and more various types of occupancies are combined into the same buildings. A rapidly developing trend is a desire for mixed-use spaces to support lifestyle activities. An increasing number of people are working from home, so they need flexible mixed-use spaces that can accommodate their lifestyle. People are on the lookout for more luxury amenities, such as full fitness and yoga studios, conference centers with commercial kitchens, rooftop pools and spas, and lobby bars and coffee shops. This Technical Standards and Design Guidelines (TSDGs) contains information intended as minimum standards for constructing and equipping new Mixed Use Building projects. Insofar as practical, these standards relate to desired performance or results or both. Details of Architectural and Engineering are assumed to be part of good design practice and local building regulations. This document covers mixed-use building facilities common to a multitude of individual facilities. Facilities with unique services will require special consideration. However, sections herein may be applicable for parts of any facility and may be used where appropriate. The Property Developer will supply for each project a functional program for the facility that describes the purpose of the project, the projected demand or utilization. The TSDG includes a description of each function or service; the operational space required for each function; the types of all spaces; the special design features; the systems of operation; and the interrelationships of various functions and spaces. The functional program includes a description of those services necessary for the complete operation of the facility. The functional programs could be applied in the development of project design and construction documents. These standards assume that appropriate architectural, engineering and technology practices and compliance with applicable codes will be observed as part of normal professional service and require no separate detailed instructions. Specialist designers adopting the TSDGs are encouraged to apply design innovations and the property developer to grant exceptions where the intent of the standards is met. Sustainability and Energy Conservation Energy efficiency being a part of the building code requirement in many states, the trend is moving toward achieving it. Higher-performing building envelopes and higher-performing HVAC and lighting systems are some of the essential components to meet current energy codes. The importance of Environmental Sustainability and Energy Conservation is fully considered in all phases of facility design development. Proper planning and selection of building materials, mechanical and electrical systems, as well as efficient utilization of space and climatic characteristics that will significantly reduce overall energy consumption are fully described. The quality of the building facility environment is undoubtedly supportive of the occupants and functions served. New and innovative systems that accommodate these considerations while preserving cost effectiveness has been encouraged. Architectural elements that reduce energy consumption are considered part of the TSDG. In addition to Energy Conservation, buildings will be designed to minimize water consumption and operating costs without reducing occupancy standards, occupant health safety or comfort. Water conservation measures such as water-recycling including gray water and rain water collection, water purification, and sewerage recycling are included for consideration and recommendation in the project specific building energy brief. The integration of innovative water efficiency measures, such as storm water management, rainfall capture, treated effluent reuse, roof gardens and other alternative sources of water supply are fully described. Technology In todays ever-changing environment, technological standardization and integration of systems is essential. Technology is viewed as a competitive tool that contributes to the improvement of building occupant services and operating efficiencies. As the importance of access to information increases, so do customer demands for such services. The Intelligent Buildings Market is a rapidly evolving segment that is being influenced by a number of emerging trends. Mobile communications connect people to work, entertainment and each other in ways that boost productivity and enhance lives. Both Operational Technology (OT) and Informational Technology (IT) have entirely changed, and it will change even more as we get deeper into the Internet of Things (IOT). In-Building Wireless (IBW) communications provide the critical link to enable the use of cell phones, pagers, PDAs, two-way radios, wireless LANs, emergency communications and wireless building system devices within an enclosed structure. The technology disciplines (telecom, security, building automation, and lighting) have been going through a convergence over the past several years, with telecom wired and wireless networks becoming the common utility for all the technology disciplines.

This book outlines the underlying principles on which modern road lighting is based, and provides the reader with knowledge of how these principles should be applied in practice. This book offers a completely fresh approach to the subject, reflecting how the technology of road lighting has progressed to keep up with the changes in lamp technology, especially in solid state light sources, and the increasing awareness of energy use and environmental issues. The book is divided into three parts. Part One describes lighting of open roads, with chapters discussing visual performance and comfort (including the effects of mesopic vision and age), and international standards and recommendations for road lighting. Lighting equipment is introduced; specifically lamps and luminaires in terms of their practical properties and features, but also the road surface and its characteristics. A chapter on Lighting Design makes the link between theory and practice, providing the reader with the knowledge needed for effective lighting design, including aspects relating to sustainability. The final chapter of Part One deals with lighting calculation conventions and measurements. Part Two is devoted to light pollution. The negative consequences of light pollution are described and tactics to restrict light pollution explained. Lighting criteria are defined that can be used by the lighting designer to guarantee installations stay within acceptable limits. International standards and recommendations on the restriction of light pollution are discussed. Part Three is devoted to tunnel lighting, with chapters discussing visual performance in tunnel environments, lighting criteria, standards and recommendations, and concluding with a chapter on tunnel lighting equipment and design. This book is a valuable resource for road lighting designers and engineers, students of lighting design and engineering, town planners, traffic engineers, environmental specialists, and lamp and luminaire developers and manufacturers.
