Low Impact Building

This guide to the designs, technologies and materials that really make green buildings work will help architects, specifiers and clients make informed choices, based on reliable technical information. Low Impact Building: Housing using Renewable Materials is about changing the way we build houses to reduce their ‘carbon’ footprint and to minimise environmental damage. One of the ways this can be done is by reducing the energy and environmental impact of the materials and resources used to construct buildings by choosing alternative products and systems. In particular, we need to recognise the potential for using natural and renewable construction materials as a way to reduce both carbon emissions but also build in a more benign and healthy way. This book is an account of some attempts to introduce this into mainstream house construction and the problems and obstacles that need to be overcome to gain wider acceptance of genuinely environmental construction methods. The book explores the nature of renewable materials in depth: where do they come from, what are they made of and how do they get into the construction supply chain? The difference between artisan and self-build materials like earth and straw, and more highly processed and manufactured products such as wood fibre insulation boards is explored. The author then gives an account of the Renewable House Programme in the UK explaining how it came about and how it was funded and managed by Government agencies. He analyses 12 case studies of projects from the Programme, setting out the design and methods of construction, buildability, environmental assessment tools used in the design, performance in terms of energy, air tightness, carbon footprint and post-occupancy issues. The policy context of energy and sustainability in the UK, Europe and the rest of the world is subjected to a critical examination to show how this affects the use of natural and renewable materials in the market for insulation and other construction materials. The debate over energy usage and embodied energy is discussed, as this is central to the reason why even many environmentally progressive people ignore the case for natural and renewable materials. The book offers a discussion of building physics and science, considering energy performance, moisture, durability, health and similar issues. A critical evaluation of assessment, accreditation and labelling of materials and green buildings is central to this as well as a review of some of the key research in the field.

This book is the inspirational story of one project that shows you how you can become involved in building and running your neighbourhood. The author, co-founder of Lilac (Low Impact Living Affordable Community), along with other members of the community and the project team, explains how a group of people got together to build one of the most pioneering ecological, affordable cohousing neighbourhoods in the world. The book is a story of perseverance, vision and passion, demonstrating how ordinary people can build their own affordable, ecological community. The book starts with the clear values that motivated and guided the project’s members: sustainability, co-operativism, equality, social justice and self-management. It outlines how they were driven by challenges and concerns over the need to respond to climate change and energy scarcity, the limits of the ‘business as usual’ model of pro-growth economics, and the need to develop resources so that communities can determine and manage their own land and resources. The author’s story is interspersed with vignettes on topics such as decision making, landscaping, finance and design. The book summarises academic debates on the key issues that informed the project, and gives technical data on energy and land issues as well as practical ‘how-to’ guides on a range of issues such as designing meetings, budget planning and community agreements. Low Impact Living provides clear and easy to follow advice for community groups, practitioners, government, business and the development sector and is heavily illustrated with drawings and photographs from the architectural team.

This book provides an insightful overview of the current state of earth building. The author approaches the subject from the perspective of the building material’s life cycle, featuring in-depth explanations of the cycle's individual steps: extraction and classification of construction soil; production of earth building materials and earthen structures; planning, construction and renovation of earth buildings; and demolition and recycling of earthen structures. This unique resource provides examples of sophisticated earth building projects and illustrates the diverse applications of earth as a building material. Compared to conventional mineral building materials, earth possesses particularly positive ecological qualities such as its energy balance and recyclability. Architects, engineers, students, manufacturers and distributors of building materials, building contractors, building biologists, public authorities and preservationists will benefit from this book’s ample coverage of restoring, optimizing and building with this material of the past, present and future.

The One Planet Life demonstrates a path for everyone towards a way of life in which we don’t act as if we had more than one planet Earth. The difference between this approach and others is that it uses ecological footprint analysis to help to determine how effective our efforts are. Much of the book is a manual – with examples – on how to live the 'good life' and supply over 65% of your livelihood from your land with mostly positive impacts upon the environment. It examines the pioneering Welsh policy, One Planet Development, then considers efforts towards one planet living in urban areas. After a foreword by BioRegional/One Planet Living co-founder Pooran Desai and an introduction by former Welsh environment minister Jane Davidson, the book contains: An essay arguing that our attitude to planning, land and development needs to change to enable truly sustainable development. Guidelines on finding land, finance, and creating a personal plan for one planet living. Detailed guides on: sustainable building, supplying your own food, generating renewable energy, reducing carbon emissions from travel, land management, water supply and waste treatment. 20 exemplary examples at all scales – from micro-businesses to suburbs – followed by Jane Davidson’s Afterword. The book will interest anyone seeking to find out how a sustainable lifestyle can be achieved. It is also key reading for rural and built environment practitioners and policy makers keen to support low impact initiatives, and for students studying aspects of planning, geography, governance, sustainability and renewable energy.

Global populations have grown rapidly in recent decades, leading to ever increasing demands for shelter, resources, energy and utilities. Coupled with the worldwide need to achieve lower impact buildings and conservation of resources, the need to achieve sustainability in urban environments has never been more acute. This book critically reviews the fundamental issues and applied science, engineering and technology that will enable all cities to achieve a greater level of metropolitan sustainability, and assist nations in meeting the needs of their growing urban populations. Part one introduces key issues related to metropolitan sustainability, including the use of both urban metabolism and benefit cost analysis. Part two focuses on urban land use and the environmental impact of the built environment. The urban heat island effect, redevelopment of brownfield sites and urban agriculture are discussed in depth, before part three goes on to explore urban air pollution and emissions control. Urban water resources, reuse and management are explored in part four, followed by a study of urban energy supply and management in part five. Solar, wind and bioenergy, the role of waste-to-energy systems in the urban infrastructure, and smart energy for cities are investigated. Finally, part six considers sustainable urban development, transport and planning.
