"Our future depends on low-energy buildings with great indoor air quality. The Power of Existing Buildings is the evidence-based resource showing exactly how to do it."
— Anjanette Green, Director, Standards Development, RESET
"Owners lack confidence that their investments in existing buildings will lead to improved performance in operations, so quite often they do nothing. The Power of Existing Buildings lays out the building science and technology-based tools available today that are essential to fully integrating design, construction, and operations, ultimately increasing an owner's return on investment. The more integration on a project, the higher the return."
— Bob Berkebile, Principal Emeritus, bnim
"Today, most of our old building stock requires updating to reflect the current needs and demands of today's clients, as well as our new climate reality. This book offers a sound approach to tackling this task, based on the building science practices endorsed by the North American Passive House Network (NAPHN). It includes a viable financial pathway to support what must be seen as an evolution; the updating of old systems to allow the charm and character inherent in old buildings to remain viable for future generations."
— Bronwyn Barry, RA, CPHD, NAPHN Board President
"Buildings make up 80 percent of the City of Pittsburgh's carbon footprint. If we are going to make meaningful progress in reducing carbon emissions, we need to address the backlog of opportunity within our existing building stock. The Power of Existing Buildings provides a roadmap for building operators, policymakers, real estate developers, and anyone who is looking to create higher performing buildings. These techniques and strategies are key components of our game plan to push buildings to net zero."
— Grant Ervin, Chief Resilience Officer, City of Pittsburgh
"As an owner of older, public buildings, we look for cost-effective ways to extend and improve the performance of our existing structures. The Power of Existing Buildings provides a data-driven approach for building owners planning to renovate old buildings into sustainable structures with lower energy consumption and improved indoor air quality."
— Greg Stewart, Administrator, Ohio County Commission, West Virginia
"A brilliant intersection of design, technology, building science, and operations, this definitive work is the roadmap to zero in existing buildings. This is a must read."
— Laura Nettleton, Founder and Architectural Coordinator, Thoughtful Balance
"Internationally, industry leaders are successfully and affordably delivering deep energy retrofits of existing buildings. Many countries either have, or soon will have, building codes requiring such retrofits; yet how they are achieved remains unknown to many. The Power of Existing Buildings is a compelling synthesis of the fundamental principles enabling the successful delivery of such projects, and is essential reading for owners, project teams, and policy makers."
— Rob Bernhardt, Chief Executive Officer, PassiveHouse Canada
"High-performance buildings are key to achieving the UN's 2030 Agenda for Sustainable Development. Most of today's buildings will still be in use in 2050, and their energy performance must be managed. As shown in this timely book, the capability to meet the challenge exists today."
— Scott Foster, Director, Sustainable Energy, United Nations Economic Commission for Europe
"Practice meets theory. The Power of Existing Buildings describes practical, tested ways for building owners to improve the energy performance of existing buildings profitably. Illustrated with compelling, real-world examples, this book shows the opportunity inherent in existing buildings, and how we can build a better environment through thoughtful renovation."
— Victor Olgyay, Principal, Rocky Mountain Institute
