Welding is a skill any do-it-yourself enthusiast needs in his arsenal. It is only when you can join metal that you can properly repair and create. This book is the perfect introduction for beginners, and an excellent refresher for veteran welders, a work so comprehensive and so complete that most readers won't need any further instruction. "How To Weld" starts with a brief history of welding, an overview of different types of welding, and a thorough discussion of safety practices. Longtime welding instructor Todd Bridgum describes various tools and types of metals, as well as techniques and types of joints. Bridgum discusses gas, stick, wire-feed (MIG and TIG), even brazing, completing each section with a series of exercises that fully illustrate the skills he has covered. This book concludes with six projects, including construction of a welding table, gantry, and jack stands.

Retrofitting expresses, in a traditional approach, the process of improving something after it has been manufactured, constructed, or assembled. These systems integrate new technologies, new functions, and new services that increase the energy performance in existing private, public, and commercial buildings. Retrofitting for Optimal Energy Performance is a comprehensive reference source that examines environmentally conscious technologies and their applications in advancing retrofitting practices. Providing relevant theoretical frameworks and the latest empirical research findings in the area, it highlights an array of topics such as climate change, energy management, and optimization modeling, and is essential for academicians, students, researchers, engineers, architects, entrepreneurs, managers, policymakers, and building owners.

Throughout the world, there is an increasing demand on diminishing natural resources in the industrial, transport, commercial, and residential sectors. Of these, the residential sector uses the most energy on such needs as lighting, water heating, air conditioning, space heating, and refrigeration. This sector alone consumes one-third of the total primary energy resources available. By using green building and smart automation techniques, this demand for energy resources can be lowered. Green Building Management and Smart Automation is an essential scholarly publication that provides an in-depth analysis of design technologies for green building and highlights the smart automation technologies that help in energy conservation, along with various performance metrics that are necessary to facilitate a building to be known as a ""Green Smart Building."" Featuring a range of topics such as environmental quality, energy management, and big data analytics, this book is ideal for researchers, engineers, policymakers, government officials, architects, and students.
