While the first volume on building physics deals with the physical principles of heat, air and moisture behaviour of buildings, building structures and components, this second volume on applied building physics focuses on the question of what the desired performance of buildings consists of. To achieve this, knowledge of the external environmental effects and the internal live loads to which buildings are subjected is a necessary first step. Subsequently, the performance requirements and the physical correspondences are deepened with the determination of their physical parameters, at the levels of buildings, building structures and building components. Compared to the second edition, the discussion of criteria is not limited to thermal comfort, but also includes acoustic, visual and olfactory aspects. Likewise, the indoor air quality is considered in a broader way. Analyses and calculations result in sustainable buildings with a comfortable indoor climate from functional and durable
