The new Generation of Ecological Architecture Building owners today are increasingly confronted with the question of energy efficiency. Aside from mandatory national requirements and optional certificates, a general consensus of "passive house" has emerged. Within a few years this building standard has become widely spread. Depending on the climatic zone, passive houses require very different technologies, interventions and steps to be taken by the architects. These have meanwhile evolved from the formerly very uniform look of the "passive house" and are now found in buildings with very different appearances. This volume portrays approximately 60 sinlge-family passive house homes and shows a multitude of great and at the same time sustainable architecture.
