John Ziegler left his native Germany and a potential post as a professor of economics at Heidelberg University to escape the rise of Nazism. In America, he finds himself working as a game warden in Ontonagon County in Michigan's Upper Peninsula. The cold winters and the deep woods of the Upper Peninsula suit John well. He is happy living and working in the forest. Things grow more complex for John when millionaire Jacob Greenleaf offers him a job as Chief of Security for the Green Leaf Wildlife Refuge. John works hard to turn Green Leaf into a model tourist attraction to help the local economy recover from the Great Depression, but soon learns that weapons have been disappearing from several cabins at Green Leaf. John's investigation of the stolen weapons leads him to Angus McVey, the man he replaced as Chief of Security at Green Leaf. McVey's family has a history of desperate poverty and was long oppressed by the Scottish gentry at their original home on the Isle of Skye. After a lifetime of anger and bitterness, McVey vows to take revenge on Jacob Greenleaf, the American equivalent of the gentry that held his family down for so long, and John Ziegler, the man who took his livelihood. McVey takes to the woods with a bow and arrows and stalks John throughout the forests of Green Leaf, bent on eliminating John. In George Nilsen's gripping novel, The Green Leaf Retrofit, John will have to call on all of his experiences and knowledge to rid Green Leaf of McVey so the resort can provide the economic boost the county desperately needs.

A deep understanding of the implications of green roof retrofit is required amongst students and practitioners to make the decisions and take the actions needed to mitigate climate changes. Green Roof Retrofit: building urban resilience illustrates the processes undertaken to develop this new knowledge and thereby embed a deeper level of understanding in readers.Illustrative case studies and exemplars are drawn from countries outside of the core researched areas to demonstrate the application of the knowledge more broadly. Examples are used from the Americas (North and South and Canada), Oceania, Asia and other European countries.The book describes the multiple criteria which inform decision making and how this provides a way forward for making better decisions about green roof retrofit in different countries and climates.

These twelve new essays present innovative and practical ideas for addressing the harmful effects of sprawl. Sprawl is not only an ongoing focus of specialized magazines like Dwell; indeed, Time magazine has cited ?recycling the suburbs? as the second of ?Ten Ideas Changing the World Right Now.' While most conversations on sprawl tend to focus on its restriction, this book presents an overview of current thinking on ways to fix, repair, and retrofit existing sprawl. Chapters by planners, geographers, and architects present research grounded in diverse locales including Phoenix, Arizona; Seattle, Washington; Dublin, Ohio; and the Atlanta, Georgia, and Washington, D.C., metro areas. The authors address head-on the most controversial aspects of sprawl–issues of power and control, justice and equity, and American attitudes about regulating private development. But they also put these issues in practical contexts, bringing in examples of redesign that are already occurring around the country, including the retrofitting of corridors and the repurposing of the cul-de-sac. Whether fixing sprawl requires a ?cultural shift? in thinking or a ?coordinated effort? by local government, these essays testify that a combination of forethought and creativity will be needed.

This book reports on a comprehensive experimental characterization of the material, mechanical and dynamic properties of masonry infill walls. It analyses the critical parameters affecting their out-of-plane seismic behavior, including the effects of the panel support conditions, gravity load, and previous damage. Further, it offers an extensive review of infill masonry strengthening strategies and reports on the experimental assessment of various textile-reinforced mortar (TRM) strengthening solutions. It also presents the development, implementation and calibration of a numerical model to simulate the infill panels’ seismic behavior, with the corresponding findings of various tests to assess the seismic vulnerability of an infilled RC structure. All in all, this outstanding PhD thesis offers a comprehensive review of masonry infill walls, and a timely overview of numerical and experimental methods for testing and preventing the out-of-plane seismic collapse of RC buildings.

Germany is seen as a leader in thermal retrofit policy and practice, but how effective is its approach? A Critical Appraisal of Germany's Thermal Retrofit Policy examines this policy in context and assesses its effectiveness. It finds that technical constraints and the costs of retrofitting reduce the rate of progress, while planning underestimates the influence of user behavior in the form of rebound and prebound effects. A key finding is that savings can be maximized within a policy that understands the actual behavior and motivation of households, the area where most energy savings are already taking place. The book suggests a new policy paradigm that would encourage a better balance of partial and comprehensive retrofits, utilizing household behavior changes based on a better understanding of fuel saving motivation and fuel price elasticity. In this approach, the thermal building regulations would be made more flexible so that policymakers would: - Promote partial, transitional and cost-optimal retrofits, which are more certain to pay back through fuel savings if they are appropriate to building typology and homeowner budgets. - Promote comprehensive retrofits for reasons other than economic gain, focusing instead on the comfort and environmental benefits of energy-efficient homes. - Invest more heavily in educating households to heat economically, learning from the prebound effect so as to maximize the utility of the homes they currently occupy, and base payback time calculations on actual consumption. The results and findings of this book would be of interest to policymakers, researchers and graduate students alike.

Success and enjoyment with and from the bio-filter hydroponics in the aquarium, with the impressive three-dimensional aquariums, is really not rocket science. Let yourself be inspired by the idea that an aquarium with a Bio-Filter hydroponics system can also be a three-dimensional water garden. With great pleasure and growing enthusiasm. Aha; that's how a bio-filter hydroponics aquarium works. The impressive three-dimensional aquarium is a very clear work, + which on the one hand explains the details, + which also shows the interrelationships; + this also includes pictures of your own aquarium projects, + which trigger the "aha effect" in many places. The course of the book is clearly structured and optimally documented with many examples. Basic impulses, nitrate reduction against the algae plague, project planning of the three-dimensional aquarium with the active bio-filter hydroponics, setup with the active bio-filter hydroponics, retrofitting an existing aquarium to three-dimensional aquaristics with a passive bio-filter hydroponics, which plants and where from? Pick up for new starters. The book is written and illustrated in a way that is understandable for the many aquarists who are new or relatively new to aquariums with a bio-filter and hydroponics in an aquarium project. Giving ideas for professionals. The course of the book with words and pictures is never trivial for aquarists who have already dealt more intensively with filter technology for aquariums. The shapes of the three-dimensional aquariums with the hydroponic bio-filter can be created individually and the project should always be adapted to your living space, not the other way around. The course of the book shows several of my projects, each with a different shape.

The refurbishment of existing buildings is a crucial yet often neglected subject within sustainable architecture; attention is usually focused on new buildings. Many old buildings waste large amounts of energy and provide poor internal conditions for occupants through poor lighting, poor ventilation, solar penetration and glare, and poor control of heating and cooling. Demolition is an option but the refurbishment alternative is increasingly seen as more sustainable in terms of architectural value, materials use, neighbourhood disruption and waste disposal. In addition, the potential impact of low energy refurbishment is much greater than that for new build since there are many more buildings already in existence than will be built in the next 10 - 20 years, the period over which many CO2 emission targets apply. The Handbook of Sustainable Refurbishment: Non-Domestic Buildings offers architects, engineers and a wide range of building professionals practical advice, illustrated by real examples. It moves from principles of sustainable refurbishment to specific design and engineering guidance for a variety of circumstances. It emphasises the need for an integrated approach by showing how refurbishment measures interact with one another and with the occupants, and how performance is ultimately influenced by this interaction.
