Health and environmental compatibility are at the forefront of society's focus. The book demonstrates how the built environment can be aesthetically modern while also being healthy and eco-friendly. It bridges the gap between architecture as a design task and building biology concepts. Building biology is the study of the holistic interrelationships between humans and their built environment. It connects building culture with ecology and disciplines such as chemistry, biology, geology, and psychology. Using the model of the Institute for Building Biology and Sustainability, building biological criteria and approaches are explained in detail. Numerous other current projects illustrate how these principles are implemented in responsible, healthy, and therefore sustainable architecture.
