Bau-Biologie—the science of the holistic interactions between living organisms and their surroundings, the study of the impact of the built environment on human health, and the application of this knowledge to build healthy homes and workplaces.

"To support personal and planetary health, we need healthy and conserving homes; homes that help us to lead a new lifestyle; homes that are designed not to damage the environment but to bring positive regeneration to it; homes, in fact, that are not sick, but are healing places for body, mind, spirit, and planet."

David Pearson – The New Natural House Book
