Regreening the Built Environment : Nature, Green Space, and Sustainability
Now in its second volume, Regreening the Built Environment provides an overview of physical and social environmental challenges that the planet is facing and presents solutions that restore ecological processes, reclaim open space, foster social equity, and facilitate a green economy. Healing the planet requires a combination of strategies networked across multiple scales of development, including buildings, sites, communities, and regions.Case studies from a range of locations in the United States, Denmark, Vietnam, Germany, South Korea, Switzerland, France, and the United Kingdom, among others, demonstrate how existing gray infrastructure can be retrofitted with green infrastructure and low-impact development techniques.From this, the author shows how a building can be designed that creates greenspace or generates energy; likewise, a roadway can be a parkway, an alley can be a wildlife corridor, and a parking surface can be a garden.This new edition also includes case studies that have successfully reconnected communities that were fragmented by unjust planning practices and irresponsible patterns of development, resilient design solutions in response to natural disasters, passive design strategies that can make interior spaces more efficient and healthier, and expanded discussions on capturing carbon, renewable energy, agriculture, waste, public transit, and adaptive reuse, including innovative ideas on how to reimagine the shopping mall in the era of e-commerce. The strategies presented in this book will stimulate discussions within the design profession and will be of great interest to students and practitioners of environmental studies, architecture, landscape architecture, and urban design.

What is the efficiency of a space heater with 100% efficiency?
A space heater with 100% efficiency would convert all the electrical energy it consumes into heat, making it extremely efficient. This means that all the energy input is converted into useful output, with no waste. However, it's important to note that achieving 100% efficiency in real-world devices is extremely difficult due to factors such as heat loss and other inefficiencies in the system.
-
What is energy efficiency?
Energy efficiency refers to using less energy to perform the same task or function, ultimately reducing energy waste and lowering energy costs. This can be achieved through various methods such as using energy-efficient appliances, improving insulation in buildings, and implementing energy-saving practices in industrial processes. Energy efficiency is an important aspect of sustainable development and can help reduce greenhouse gas emissions and mitigate the impact of climate change. By improving energy efficiency, we can conserve natural resources and create a more sustainable and environmentally friendly energy system.
-
What is the efficiency?
Efficiency is a measure of how well resources are utilized to achieve a specific goal or outcome. It is often expressed as the ratio of output to input, showing how much output is produced per unit of input. High efficiency means that resources are being used effectively and wastage is minimized, leading to optimal results. In contrast, low efficiency indicates that resources are not being utilized efficiently, resulting in lower productivity and potentially higher costs.
-
Does waste reduction go beyond waste recycling?
Yes, waste reduction goes beyond waste recycling. While recycling is an important part of waste management, waste reduction focuses on minimizing the amount of waste produced in the first place. This can be achieved through practices such as reducing packaging, reusing items, and implementing more sustainable production processes. By focusing on waste reduction, we can decrease the overall environmental impact of waste and move towards a more circular and sustainable economy.

Green Development : Environment and Sustainability in a Developing World
The concept of sustainability lies at the core of the challenge of environment and development, and the way governments, business and environmental groups respond to it.Green Development provides a clear and coherent analysis of sustainable development in both theory and practice.Green Development explores the origins and evolution of mainstream thinking about sustainable development and offers a critique of the ideas behind them.It draws a link between theory and practice by discussing the nature of the environmental degradation and the impacts of development.It argues that, ultimately, ‘green’ development has to be about political economy, about the distribution of power, and not about environmental quality.Its focus is strongly on the developing world. The fourth edition retains the broad structure of previous editions, but has been updated to reflect advances in ideas and changes in international policy.Greater attention has been given to the political ecology of development, market-based and neoliberal environmentalism, and degrowth.This fully revised edition discusses: the origins of thinking about sustainability and sustainable development, and its evolution to the present day; the ideas that dominate mainstream sustainable development (including natural capital, the green economy, market environmentalism and ecological modernisation); critiques of mainstream ideas and of neoliberal framings of sustainability, and alternative ideas about sustainability that challenge ‘business as usual’ thinking, such as arguments about limits to growth and calls for degrowth; the dilemmas of sustainability in the context of forests, desertification, food and farming, biodiversity conservation and dam construction; the challenge of policy choices about sustainability, particularly between reformist and radical responses to the contemporary global dilemmas. Green Development offers clear insights into the challenges of environmental sustainability, and social and economic development.It is unique in offering a synthesis of theoretical ideas on sustainability and in its coverage of the extensive literature on environment and development around the world.The book has proved its value to generations of students as an authoritative, thought-provoking and readable guide to the field of sustainable development.

Can the efficiency be zero?
No, efficiency cannot be zero. Efficiency is a measure of how well a system or process uses inputs to produce outputs, and it is always a positive value between 0 and 1. A value of zero would indicate that no useful work is being done, which is not possible in a functioning system. If a system is not producing any useful output, its efficiency would be close to zero but not exactly zero.
-
What are power and efficiency?
Power is the rate at which work is done or energy is transferred, and it is measured in watts. It represents the ability to exert force or to perform work. Efficiency, on the other hand, is a measure of how well a system or process uses energy or resources to accomplish a task. It is the ratio of useful output to total input, and it indicates how effectively energy is being converted into useful work. In summary, power is the capacity to do work, while efficiency is the measure of how well that work is being done.
-
