In the United States, buildings account for 40% of primary energy use, 72% of electricity consumption, and 39% of CO2 emissions. Indoor lighting accounts for a large portion of our energy use, and we sorely need to develop better, more efficient systems to illuminate our institutions and places of commerce as well as our homes.
But as we push for greater efficiencies and reduced life-cycle impacts, and as new green construction codes and standards are adopted, it is imperative that we avoid sacrificing good lighting design that enhances our productivity, our comfort, and our health. With this in mind, this book provides an overview of the basic concepts of quality, indoor lighting, and explains concepts like visual comfort, visual interest, and integrated design as they relate to the practice of lighting design.
Energy efficient lighting technologies, including LED lighting and digital control systems, and design strategies that increase visual comfort and productivity are discussed in plain language, and examined in a straightforward way to give the reader, whether an architect, interior designer, engineer, building trades professional, or student a broad understanding of the art and science of energy efficient quality lighting.
