The objectives of Journal of Building Physics are to foster and promote scientifically thorough advancement of all the areas of non-structural performance of a building and particularly in heat, air, moisture transfer. Our goal is to enhance deeper insight and understanding, and enable the development of scientifically-based design tools, which are crucial for the implementation of a performance-based engineering approach in building design. Recently the scope of the journal has been broadened, in response to readers' interests--and as a result of the shift in focus of the leading-edge building research organizations. Formerly titled Journal of Thermal Envelope and Building Science, the vision of the JBP is to facilitate the integration and implementation of a scientific approach in building physics with the various domains of building performance.
