Book Description
The building industry is influenced by many factors and trends reflecting the current situation and developments in social, economic, technical, and scientific fields. One of the most important trends seeks to minimize the energy demand. This can be achieved by promoting the construction of buildings with better thermal insulating capabilities of their envelopes and better efficiency in heating, ventilation, and air conditioning systems. Any credible assessment of building energy performance includes the identification and simulation of heat and mass transfer phenomena in both the building envelope and the interior of the building. As the interaction between design elements, climate change, user behavior, heating effectiveness, ventilation, air conditioning systems, and lighting is not straightforward, the assessment procedure can present a complex and challenging task. The simulations should then involve all factors affecting the energy performance of the building in questions. However, the appropriate choice of physical model of heat and mass transfer for different building elements is not the only factor affecting the output of building energy simulations. The accuracy of the material parameters applied in the models as input data is another potential source of uncertainty. For instance, neglecting the dependence of hygric and thermal parameters on moisture content may affect the energy assessment in a significant way. Boundary conditions in the form of weather data sets represent yet another crucial factor determining the uncertainty of the outputs. In light of recent trends in climate change, this topic is vitally important. This Special Issue aims at providing recent developments in laboratory analyses, computational modeling, and in situ measurements related to the assessment of building energy performance based on the proper identification of heat and mass transfer processes in building structures. Potential topics include but are not limited to the following: -Development, calibration, and validation of advanced mathematical models for the description of heat and mass transfer in building materials and structures -Computational modeling of heat and mass transfer in building materials and structures aimed at energy performance assessment Boundary conditions for building energy performance simulations in light of climate change trends -Advanced experimental techniques for the determination of heat and mass transport and the storage properties of building materials -On site monitoring and verification of building energy performance -Research and development of new materials with high potential to improve the energy performance of buildings

Book Description
This book discusses the issues relevant to the evaluation of the thermal energy balance of buildings in southern Europe and equips readers to carry out optimal building energy-performance assessments taking into account the peculiarities of the climatic context. Evaluation of building energy performance in this region is complex, since the significant need for cooling means that the effect of thermal capacity, glazed surfaces and ventilation and shading strategies have to be carefully considered when determining the indoor operative temperatures. This is fully explained, and critical issues in the application of the commonly employed, simplified procedures and assumptions are identified. In addition to the theoretical analysis, there are case studies that explore the energy performances of a set of typical building typologies within the variability of the Italian climate, considered as representative of conditions in southern Europe. These descriptions will support energy consultants and other stakeholders in assessing building energy performances beyond the mere simplified standard assumptions. Furthermore, the numerous graphs and tables documenting data can be easily adopted to serve as design advice tools for both new constructions and retrofits.

Book Description
Bad experiences with construction quality, the energy crises of 1973 and 1979, complaints about "sick buildings", thermal, acoustical, visual and olfactory discomfort, the need for good air quality, the move towards more sustainability - all these have accelerated the development of a field that, for a long time, was hardly more than an academic exercise: building physics (in English speaking countries sometimes referred to as building science). The discipline embraces domains such as heat and mass transfer, building acoustics, lighting, indoor environmental quality and energy efficiency. In some countries, fire safety is also included. Through the application of physical knowledge and its combination with information coming from other disciplines, the field helps to understand the physical phenomena governing building parts, building envelope, whole buildings and built environment performance, although for the last the wording "urban physics" is used. Today, building physics has become a key player on the road to a performance based building design. The book deals with the description, analysis and modeling of heat, air and moisture transport in building assemblies and whole buildings with main emphasis on the building engineering applications, including examples. The physical transport processes determine the performance of the building envelope and may influence the serviceability of the structure and the whole building. Compared to the second edition, in this third edition the text has partially been revised and extended.
