Bad experiences with construction quality, the energy crisis of  1973 and 1979, complaints about ‘sick buildings’,  thermal, acoustical, visual and olfactory discomfort, all have  accelerated the development of a field, which until some 40 years  ago was hardly more than an academic exercise: building  physics.
  Building physics combines several knowledge domains such as heat  and mass transfer, building acoustics, lighting, indoor  environmental quality and energy efficiency. In some countries,  also fire safety is included. Through the application of existing  physical knowledge and the combination with information coming from  other disciplines, the field helps to understand the physical  phenomena governing assembly, although for the last the wording  ‘urban physics’ is used. Building physics has a true  impact on performance based building design.
   This volume focuses on heat, air, moisture transfer and its usage  in building engineering applications.
