Book Description
Buildings account for 35 percent of the world s energy use and a similar percentage of CO2 emissions. In order to ensure adequate energy supplies and to curtail the growth of CO2 emissions, it is essential that building energy consumption is significantly reduced. One way this can be achieved is through the introduction of sustainable building design enabled by innovative building simulation tools, for example the whole building heat, air and moisture (HAM) transfer model. The hygrothermal transfer between building envelopes and indoor air has a significant influence on the indoor environment and energy performance of buildings. However in most applications, building envelope designers attempt to predict the hygrothermal performance of an individual building element by uncoupling the system from interactions of the other envelope components to both indoor/outdoor environments. A more advanced building performance evaluation approach requires the direct coupling of all building envelope systems with HVAC systems and indoor/outdoor environments. The book will focus on the development of a coupled HAM model for whole building simulation.

Book Description
Note: New editions of this book have been published: the 3rd edition in 2017, and the 4th edition in September 2023. 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 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, building envelope, whole building and built environment performance, 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.

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.

Book Description
The current indoor, building envelope and energy analysis tools are in the form of stand-alone packages, where there is no direct link among them but rather simplifying assumptions are made on the indoor conditions or building envelope when designing for one. For example, indoor models attempt to predict the indoor condition with a simplified approach or no coupling with the building components, which in fact could have a moisture buffering effect. Building envelope models use predefined simple indoor environmental conditions in assessing the hygrothermal performance of a particular building component. Energy models usually ignore the moisture effect on the thermal transport and storage properties of materials. Incorrect prediction of indoor humidity condition and ignoring moisture effect in the energy calculation may lead to over or under sizing of HVAC equipments and the associated effects on building enclosure moisture performance and occupants' comfort and health. In reality, the indoor environmental conditions, more specifically, temperature and relative humidity, are unknown quantities, and have to be determined from the heat and mass balance in the zone considering the heat and mass transfer across the building enclosure, the internal heat and moisture generated by occupants and their activities, and the heat and moisture supply from mechanical systems depending on the mode of operation of the building. In this research work, a whole building hygrothermal model, which considers the building as a system and deals with the dynamic heat, air and moisture (HAM) interactions among building envelope components, indoor environment and mechanical systems, is developed. The model takes into account the three interrelated and coupled components and evaluates the indoor temperature and relative humidity, building enclosure moisture performance and energy efficiency of the building in an integrated manner on a single platform. The model along with two primary models, namely building envelope and indoor models, are benchmarked against internationally published analytical, numerical and experimental test cases. After successful benchmarking, its usefulness in practical applications are demonstrated through indoor humidity modeling of an existing building, and evaluation of the subsequent retrofit options to attain indoor humidity that is favorable to occupants' comfort and health and at the same time high energy efficiency and durable building. The whole building heat and moisture analysis that are carried out in this research work underlines the importance of an integrated design approach in designing new buildings or retrofitting existing buildings in order to attain an optimized building performance.

Book Description
Describes a comprehensive laboratory study to verify the accuracy of MOIST, a personal computer program that predicts the transient one-dimensional heat and moisture transfer in building envelopes. The program allows the user to vary building materials, their relative placement within the building envelope, and the geographic location of the building. Describes the results of the comparison between MOIST and experimental measurements. Charts and tables.

Book Description
A third or more of the energy consumption of industrialized countries is expended on creating acceptable thermal and lighting conditions in buildings. As a result, building heat transfer is keenly important to the design of buildings, and the resulting analytical theory forms the basis of most design procedures. Analytical Theory of Building Heat Transfer is the first comprehensive reference of its kind, a one-volume compilation of current findings on heat transfer relating to the thermal behavior of buildings, forming a logical basis for current design procedures.
