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.

This brief targets primarily small-to medium-size historic buildings, both residential and commercial. However, the general decision-making principles outlined here apply to buildings of any size and complexity. This guidance is provided in accordance with the Secretary of the Interior's Standards for Rehabilitation to ensure that the architectural integrity of the historic property is preserved.

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 to reimagine existing buildings to create a more sustainable future The construction and operation of buildings is responsible for 41 percent of all primary energy use and 48 percent of all carbon emissions, and the impact of the demolition and removal of an older building can greatly diminish the advantages of adding green technologies to new construction. In Building Reuse, Kathryn Rogers Merlino makes an impassioned case that truly sustainable design requires reusing and reimagining existing buildings. Additionally, Merlino calls for a more expansive view of preservation that goes beyond keeping only the most distinctive structures based on their historical and cultural significance to embrace the creative reuse of even unremarkable buildings for their environmental value. Building Reuse includes a compelling range of case studies—from a private home to an eighteen-story office building—all located in the Pacific Northwest, a region with a long history of sustainable design and urban growth policies that have made reuse projects feasible. Reusing existing buildings can be challenging to accomplish, but changing the way we think about environmentally conscious architecture has the potential to significantly reduce energy consumption, carbon emissions, and waste.
