Building physics

Mehr zum Buch

Bad experiences with construction quality, the energy crises of the 1970s, and concerns about 'sick buildings' have spurred the development of building physics, a field that was largely academic until recently. By applying existing physical knowledge and integrating insights from various disciplines, this field enhances our understanding of the physical performance of buildings and informs effective design and construction practices. The author draws on thirty years of teaching, research, and consultancy to present a comprehensive examination of heat and mass transport in building components. Key topics include steady and non-steady state heat conduction, convection, and thermal radiation, alongside essential thermal concepts such as reference temperatures, surface film coefficients, thermal transmissivity, and thermal bridging. The book also delves into water vapor dynamics, analyzing moisture flow in building materials and components, while addressing engineering concepts for assessing risks related to mold, mildew, and condensation. In the final section, heat and mass transfer are integrated into a cohesive model that reflects the real hygrothermal response of building components, as demonstrated in field experiments. The text successfully bridges theory and practical application, avoiding oversimplification and ensuring clarity throughout.
