Ecology has significantly influenced architecture in the past decade, often due to the energy-efficient design of buildings. Advancements like heat pumps, zero-energy technology, and heat recovery ventilation have transformed homes into high-tech machines. However, “energy efficiency” is often treated as a separate component, unlike in the past where ecology was integral to architectural design. This book explores European vernacular architecture that integrates ecology holistically, but also discusses the broader socio-economic context of ecology in architecture through interviews with experts like Jane Withers, Janez Potočnik, Michael Braungart, and Timothy Morton.
