This eye-opening book reports the results of a large-scale study based on extensive financial and technical analyses of more than 150 green buildings in the United States and ten other countries. Using sophisticated modeling techniques, the study analyzes the costs and financial benefits of building green on both large and small scales, and addresses the role of the built environment in reducing carbon dioxide emissions. The author reports that green buildings cost roughly 2 per cent more to build than conventional buildings - far less than previously assumed - and provide a wide range of financial, health, and social benefits. In addition, green buildings reduce energy use by an average of 33 per cent. The book also evaluates the cost-effectiveness of 'green community development' and presents the results of the first-ever survey of green buildings constructed by faith-based organizations. A compelling combination of solid facts and specific examples, it proves that green design is both cost-effective and earth-friendly.
“By every measure, green building is an idea whose time is now. Kats’ ongoing work in this area is part of the reason, and this book will be an invaluable resource to builders, cities and companies on why and how to cost-effectively green their own built worlds.”
(Rick Fedrizzi president and CEO, USGBC 20090825)
“Building green offers the potential for important health and economic benefits. As our nation faces the twin mandates to improve health and control costs, analyses such as this one— including full benefit accounting— are indispensable.”
(Howard Frumkin director, National Center for ENV Health/ ATSTR, CDC )
“Everyone who is serious about climate change should get this book. Greg Kats brings a deep knowledge of energy and construction to show that the benefits of green construction outweigh the costs and could jump-start a national revolution toward the use of renewable energy sources.”
(Don Kennedy president emeritus, Stanford University; Bing Professor of EnvScience and Policy )

The Integrative Design Guide to Green Building: Redefining the Practice of Sustainability (Sustainable Design) >> By 7group (Author), Bill Reed (Author), S. Rick Fedrizzi (Foreword)
Author: 7group (Author), Bill Reed (Author), S. Rick Fedrizzi (Foreword) | Size: 29.44 MB | Format:PDF | Publisher: Wiley; 1 edition | Year: April 13, 2009 | pages: 433 | ISBN: ISBN-10: 0470181109 ISBN-13: 978-0470181102
"The members of 7group and Bill Reed are examples writ large of the kind of leadership that is taking this idea of green building and forming it into reality, by helping change minds, building practice, and design process."
—from the Foreword by S. Rick Fedrizzi President, CEO, and Founding Chair, U.S. Green Building Council
A whole-building approach to sustainability
The integrative design process offers a new path to making better green building decisions and addressing complex issues that threaten living systems. In The Integrative Design Guide to Green Building: Redefining the Practice of Sustainability, 7group's principals and integrative design pioneer Bill Reed introduce design and construction professionals to the concepts of whole building design and whole systems. With integrative thinking that reframes what sustainability means, they provide a how-to guide for architects, designers, engineers, developers, builders, and other professionals on incorporating integrative design into every phase of a project.
This practical manual:
Explains the philosophy and underpinnings of effective integrative design, addressing systems thinking and building and community design from a whole-living system perspective
Details how to implement integrative design from the discovery phase to occupancy, supported by process outlines, itemized tasks, practice examples, case studies, and real-world stories illustrating the nature of this work
Explores the deeper understanding of integration that is required to transform architectural practice and our role on the planet
This book, both practical and thoughtful, will help you deliver your vision of a sustainable environment.
7group, based in Kutztown, Pennsylvania, includes principals John Boecker, Scot Horst, Tom Keiter, Andrew Lau, Marcus Sheffer, and Brian Toevs, who bring a unique integration of expertise in design, engineering, energy and daylight modeling, materials assessments, commissioning, education, and communications to their work. Internationally recognized thought leaders in the green building movement, they have led countless teams through the practical implementation of integrative design on building projects of all types around the world. 7group also has been directly and deeply involved with the development of the LEED® Green Building Rating System, including experience on more than 100 LEED projects. Scot Horst currently serves as chair of the U.S. Green Building Council's LEED Steering Committee.

Calculating wind resistance is one important process in the design of highway bridges. The current codes of many countries include different rules and formulas regarding the calculation of wind resistance. In this paper, the transverse‐direction wind loads on long‐span girder bridges with tall piers were calculated using six codes from different countries under various terrain, pier height, and girder length conditions. The pier‐bottom shear force and moment results of transverse wind loads calculated using these six codes were compared to those obtained using the buffeting frequency domain method. Results showed that, in class B terrain, wind load results predicated by China's 2004 general codes for the design of highway bridges and culverts, China's 2004 wind‐resistant design specifications for highway bridges, Japan's 2007 wind resistant design manual for highway bridges, and part two of Britain's 2006 steel, concrete, and composite bridge specifications for loads resembled each other closely. Some difference was found to exist among class A, C, and D terrain. The 2007 AASHTO LRFD bridge design specifications and China's 2001 load codes for the design of building structures showed significant differences from the other four codes on all kinds of terrain. The applicability of the wind load rules in the AASHTO LRFD bridge design specifications to long‐span girder bridges with tall piers merits further discussion. China's wind load calculations of load code for the design of building structures mainly depended on the experience parameters of architectural structures with large dimensions, and had limited applicability to bridge structures. For long‐span girder bridges with tall piers, such as bridges with span length to width or depth ratios exceeding 30 or pier height to transverse width ratio exceeding 10.7, the wind load calculated using these codes was generally underestimated due to the neglect of the effects of aeroelastic forces, which must be taken into account in the design of these kinds of bridges.

Buckling Analysis of a Long‐Span Roof Structure Collapsed during Construction
Author: N. Augenti1 and F. Parisi2 | Size: 3.41 MB | Format:PDF | Publisher: ASCE | Year: 2011 | pages: 46
Numerical simulation of damage and collapse mechanisms suffered by engineering structures can be an effective tool for a quantitative assessment of their causes. Large displacement inelastic analysis may be required in the case of highly flexible structures such as steel roofs which frequently experience large failures or even collapse owing to buckling. This paper deals with the collapse of a long‐span steel roof structure which fell down suddenly during construction as a result of an out‐of‐plane buckling phenomenon induced by a gust of wind. Forensic investigations were carried out on behalf of the judicial authority in order to identify the causes of the accident. Based on detailed information gathered from site surveys and project documents, a three‐dimensional numerical model of the as‐built structure was created and buckling analyses were performed to assess the safety level at the moment of the collapse. The as‐built structure was braced through some purlins and steel cables fixed at the ground level. Structural stability was also investigated under further modeling assumptions to compare the effectiveness of several bracing systems in preventing the collapse. Analysis results showed that the as‐built structure was in an unstable equilibrium condition when the wind breeze occurred. Temporary bracing elements installed on the structure instead of concentric roof braces were not sufficient to ensure the overall stability.
