This book examines all technology in the home from a systemic perspective. It presents concrete possibilities for symbiotically and functionally linking the areas of heating, electricity, ventilation, and sanitation according to building biology criteria. Based on traditional craftsmanship and human biology, the work investigates the fundamental requirements for a life-appropriate building and its environment. The author develops constructional solutions to utilize existing resources and avoid a technical overload of the living environment. The decentralized use of renewable energy sources is as much a focus as the interplay between technology and building construction. In the spirit of sustainability and value creation, this book sheds light on the general handling of resources in the living environment as well as potential opportunities.
