Energy-efficient, ecological, future-proof Equipped for the energy transition: 25 exemplary houses, clearly described and extensively illustrated. Not just since the current debates about heating energy and thermal insulation: the demand for new, sustainable solutions in house construction is high. What is often still lacking are good examples that show how all requirements can be met while building or renovating in an affordable and architecturally attractive way. This volume presents 25 exemplary projects from German-speaking countries. The spectrum ranges from the modern passive house and the particularly ambitious plus-energy house to the exemplary refurbished, energy-optimized old building or listed building. The focus is on compact construction, the reuse of materials and historical building materials, environmentally friendly products, renewable raw materials and how CO2 can be avoided, for example through preservation instead of demolition. Another focus is on energy efficiency: how residential buildings can manage with very little energy or how they can even generate it themselves. Concepts for the passive use of solar energy, photovoltaic systems and storage systems as well as regenerative central heating systems play an important role here. An appendix with recommended planners, useful addresses for subsidies and further reading completes the volume. (Publisher's text - reproduced with kind permission)
