This handbook holistically summarises the principles for the energy retrofitting of historic buildings, from the first diagnosis to the adequately designed intervention: preservation of the historic structure, user comfort, and energy efficiency. The content was developed by an interdisciplinary team of researchers. The wide range of different expertise, design examples, calculations, and measuring results from eight case studies makes this manual an indispensable tool for all architects, engineers, and energy consultants.

The book holistically summarizes the principles of corrective maintenance and energy retrofitting of historic and listed buildings, from diagnosis to intervention: asset preservation, user comfort, and energy efficiency. Constructions, calculations, and test series created by an interdisciplinary team of researchers in eight case studies, make the manual an indispensable planning tool.

This timely volume brings together case studies that address the urgent need to manage energy use and improve thermal comfort in modern buildings while preserving their historic significance and character. This collection of ten case studies addresses the issues surrounding the improvement of energy consumption and thermal comfort in modern buildings built between 1928 and 1969 and offers valuable lessons for other structures facing similar issues. These buildings, international in scope and diverse in type, style, and size, range from the Shulman House, a small residence in Los Angeles, to the TD Bank Tower, a skyscraper complex in Toronto, and from the Calouste Gulbenkian Foundation, a cultural venue in Lisbon, to the Van Nelle Factory in Rotterdam, now an office building. Showing ingenuity and sensitivity, the case studies consider improvements to such systems as heating, cooling, lighting, ventilation, and controls. They provide examples that demonstrate best practices in conservation and show ways to reduce carbon footprints, minimize impacts to historic materials and features, and introduce renewable energy sources, in compliance with energy codes and green-building rating systems. The Conserving Modern Heritage series, launched in 2019, is written by architects, engineers, conservators, scholars, and allied professionals. The books in this series provide well-vetted case studies that address the challenges of conserving twentieth-century heritage.

This guidance is for anyone who wishes to improve energy efficiency in an historic building. There are many reasons to do this. Improving energy efficiency will lower carbon emissions and fuel bills and often increase comfort. It also might be necessary to ensure that a building complies with legal requirements. More broadly, improving energy efficiency forms a part of the wider objective to achieve a sustainable environment. It is a widely held view that older buildings are not energy-efficient, and must be radically upgraded in order to improve their performance. In reality, the situation is more complicated, and assumptions about poor performance are not always justified. Even so, the energy and carbon performance of most historic buildings can be improved, which will help them remain viable and useful, now and in the future. But striking the right balance between benefit and harm is not easy. The unintended consequences of getting energy efficiency measures wrong (or doing them badly) include: harm to heritage values and significance, harm to human health and building fabric, and failure to achieve the predicted savings or reductions in environmental impact. Getting the balance right (and avoiding unintended consequences) is best done with a holistic approach that uses an understanding of a building, its context, its significance, and all the factors affecting energy use as the starting point for devising an energy-efficiency strategy. This 'whole building approach' ensures that energy-efficiency measures are suitable, robust, well integrated, properly coordinated and sustainable. In addition, this approach provides an effective framework for communication and understanding between the various parties involved in the process. These include assessors, designers, installers and the people who occupy and manage the building. A logical and systematic process of energy planning underpins the 'whole building approach'. This guidance describes the key stages of the process, illuminating any problems that might occur and providing solutions. It also includes checklists of practical measures that might be considered, along with links to sources of more detailed information about how to install these measures.

How should we go about making old houses energy efficient without devaluing future sustainability or the appeal and character of old homes by the use of inappropriate solutions? This practical and essential guide to retrofitting for energy efficiency seeks to provide answers to this and other the questions homeowners of old houses are asking. Whether your house is medieval and timber-framed or a Georgian, Victorian or Edwardian terrace, it can be made more energy efficient and sustainable, and this practical and comprehensive handbook will show you how. Revised and updated throughout, and with a foreword by Kevin McLoud, Old House Eco Handbook includes chapters on the building envelope; roofs and ceilings; windows and doors; walls; floors; paints; energy, airandwater; plus a brand newchapter on retrofit materials. In association with The Society for the Protection of Ancient Buildings, this is a must have for owners of old houses looking to make their homes more energy efficient and sustainable. Chapters Include: 1. Old houses can be green 2. Old house to eco house 3. The building envelope 4. Retrofit materials 5. Roofs and ceilings 6. Windows and doors 7. Walls 8. Floors 9. Paints 10. Energy, air and water 11. Old house for the future
