Building biology is the study of how buildings and their environments affect human health and well-being. It focuses on creating spaces that promote physical and mental wellness by considering factors like air quality, natural light, and materials used in construction. This field combines principles from architecture, environmental science, and health studies. Practitioners often assess buildings for harmful substances, such as volatile organic compounds (VOCs) and mold, and recommend solutions to improve indoor environments. The goal is to design spaces that are not only functional but also supportive of a healthy lifestyle.
