Because the fate of the planet is at stake, it is no longer just a question of following a particular architectural or design philosophy. Buildings consume about half the energy produced in the United States and around the world. Today, more than 50 percent of the world’s population lives in cities, a figure that is likely to rise to 60 percent over the next two decades. It is clear that timing is critical: with 900 billion ft2 (80 billion m2) of urban environment projected to be built and rebuilt in the next twenty years (an area equal to three times the total building stock of the United States), we are presented with an extraordinary window of opportunity to meet present and looming threats. Our best chance of doing so is to ensure that the architecture, planning, and development community, the primary agents shaping the built environment through design and construction, have access to the knowledge and tools necessary for the transition to a decarbonized, sustainable, and adaptive world. Professor Lechner’s book describes how to achieve this transition in the built environment. The book illustrates the many sustainable strategies available to designers and provides the information needed during the early phases of the design process, when a building’s energy consumption patterns are defined. By using the strategies presented in this book, much of the energy consumed to heat, light, and cool buildings can be dramatically reduced. Professor Lechner’s book is also an important resource for those architects who are concerned about the aesthetic aspects of sustainability. He convincingly explains and demonstrates how lessons learned from vernacular architecture can be combined with the best of modern ideas to create low-impact yet beautifully designed humane architecture. Since carbon neutral buildings can be fully powered by renewable resources, a future of lowimpact buildings is not only necessary but also elegantly achievable. EDWARD MAZRIA, AIA xi FOREWORD TO THE FIRST EDITION Professor Lechner’s book differs from most of its predecessors in several important respects: (1) he deals with the heating, cooling, and lighting of buildings, not as discrete and isolated problems, but in the holistic sense of being integral parts of the larger task of environmental manipulation; (2) he deals with the subjects not merely from the engineer’s limited commitment to mechanical and economic efficiency but from the much broader viewpoint of human comfort and physical and psychic well being; (3) he deals with these problems in relation to the central paradox of architecture—how to provide a stable, predetermined internal environment in an external Â�environment that is in constant flux across time and space; and finally, (4) he approaches all aspects of this complex subject from a truly cultural—as opposed to a narrowly technological—perspective. This attitude toward contemporary technology is by no means hostile. On the contrary, Professor Lechner handles it competently and comprehensively. But he never loses sight of the fact that the task of providing a truly satisfactory enclosure for human activity is that one must view the building as a whole. He points out, quite correctly, that until the last century or so, the manipulation of environmental factors was, of necessity, an architectural problem. It was the building itself—and only incidentally any meager mechanical equipment that the period happened to afford—that provided habitable space. To illustrate this point, he makes continuous and illuminating analysis to both high-style and vernacular traditions, to show how sagaciously the problems of climate control were tackled by earlier, prescientific, premechanized societies. This is no easy-to-read copybook for those designers seeking shortcuts to glitzy postmodern architecture. On the contrary, it is a closely reasoned, carefully constructed guide for architects (young and old) who are seeking an escape route from the energy-wasteful, socially destructive cul-de-sac into which the practices of the past several decades have led us. Nor is it a Luddite critique of modern technology; to the contrary, it is a wise and civilized explication of how we must employ technical and scientific knowledge if we in the architectural field are to do our bit toward avoiding environmental disaster. JAMES MARSTON FITCH Hon. AIA, Hon. FRIBA In memory of James Marston Fitch, architect, historian, professor, preservationist, and architectural theorist, 1909–2000. xiii PREFACE In this new edition the goal of previous editions remains: to provide the appropriate knowledge at the level of complexity needed at the schematic design stage. In the years since the first edition was published, we have moved from a shortage of information to a flood because of the Internet. This book will aid the designer because it presents the information in a concise, logical, and accessible arrangement and at a useful level. Since heating, cooling, and lighting are accomplished by adding energy to or removing it from a building, and since the consumption of energy is causing global warming, it is vital for architects to design low energy, sustainable buildings. Although sustainability deals with many issues, the energy issues are the most critical. Thus, an additional goal of this book is to provide architects with the skills and knowledge needed to create low energy and low carbon-emission buildings. In addition to improving and updating every chapter, three new chapters have been added. Chapter 17 on tropical architecture was added because a large portion of the world’s population lives in the tropical zone and because many architects trained in designing buildings in temperate climates end up designing buildings in the tropics. Case studies, formerly in Chapter 17, are now in Chapter 18. Because of the extensive information available on the Web, only a brief description is given of a personal selection of buildings. Chapter 19, the third new chapter, presents a checklist to help in the design of low energy, sustainable buildings. The checklist guides the designer through the decisionmaking process so that important options are considered at the appropriate time. This book focuses on the schematic design stage, where the key decisions are made. The graph below points out how the earliest decisions have the greatest impact on a project. A building’s cost and environmental impact are established mainly at the schematic design stage. The most basic decisions of size, orientation, and form often have the greatest impact on the resources required during both construction and operation. Thus, designs for sustainable buildings are achieved primarily by the earliest decisions in the design process rather than by add-ons and engineering decisions made after the architectural design of the building has been Â�essentially completed. The information in this book is presented to support the three-tier approach to sustainable design of the heating, cooling, and lighting of buildings. The first tier is load avoidance. Here the need for heating, cooling, and lighting is minimized by the design of the building itself. The second tier consists of using natural energies through methods such as passive solar, passive cooling, natural ventilation, and daylighting. This tier is also accomplished mainly by the design of the building itself. The third and last tier uses mechanical and electrical equipment to satisfy the needs not provided for by the first two tiers. With the knowledge and information presented in this book, the first two tiers can provide most of the thermal and lighting requirements of a building. As a consequence, the mechanical and electrical equipment of the third tier will be substantially smaller and will use much less energy than is typical now, thereby resulting in more sustainable buildings. Since tiers one and two are the domain of the architect, the role of the engineer at the third tier is to provide only the heating, cooling, and lighting that the architect could not. xv ACKNOWLEDGMENTS For the fourth edition, I would like to thank especially John Marusich for his excellent work on the new and revised drawings. Since this book is built on the previous three editions, I also want to thank again all of the people who helped me write those earlier editions. The typing and proofreading for the fourth edition were done by my son, Walden Lechner. And again, I want to thank my wife, Prof. Judith Lechner, whose help, support, and love are invaluable to me.

By detailing the many factors that contributeto the comfort in a building, this book helps architects minimizemechanical systems and energy usage over the life of the buildingby siting, building design, and landscaping to maximize naturalheating, cooling, and lighting. This new fourth edition includesnew information on integrated design strategies and designing forthe Tropics. Resources include helpful case studies, checklists,diagrams, and a companion website featuring additional cases, animage bank, and instructor materials. Designing buildings that require less energy to heat, cool, andlight means allowing the natural energy of the sun and wind toreduce the burden on the mechanical and electrical systems. Basicdesign decisions regarding size, orientation, and form have a greatimpact on the sustainability, cost, and comfort of a building.Heating, Cooling, and Lighting provides detailed guidancefor each phase of a design project. Readers will: Understand the concept of sustainability as applied to energysources Review the basic principles of thermal comfort, and thecritical role of climate Learn the fundamentals of solar responsive design, includingactive and passive solar systems as well as photovoltaics Discover how siting, architectural design, and landscaping canreduce the requirements for mechanical and electrical systems In sustainable design, mechanical, and electrical systems shouldbe used to only accomplish what the architect could not by thedesign of the building itself. With this in mind, designers requirea comprehensive understanding of both the properties of energy andthe human factors involved in thermal comfort. Heating, Cooling,and Lighting is the complete, industry-leading resource fordesigners interested in sustainable environmental control.     Download (153 Mb) Peter Frederick Smith – Architecture in a Climate of Change BIM in Small-Scale Sustainable Design Plumbing, Electricity, Acoustics: Sustainable Design Methods for Architecture Sustainable Solar Housing: Volume 2 – Exemplary Buildings and Technologies Sustainable Solar Housing: Volume 1 – Strategies and Solutions Load more posts
