Building Physics is the study of how buildings interact with their environment, focusing on energy efficiency, comfort, and sustainability. It examines factors like heat transfer, moisture control, and air quality to ensure that structures are not only functional but also healthy for occupants. By understanding these principles, architects and engineers can design spaces that maintain a comfortable climate while minimizing energy consumption. This field also involves the use of materials and technologies that enhance a building's performance. For instance, insulation helps reduce heat loss, while ventilation systems improve air quality. Ultimately, Building Physics aims to create buildings that are both environmentally friendly and cost-effective over their lifespan.
