When analyzing hygrothermal performance of building materials, components or whole buildings, computational modeling of heat, air and moisture (HAM) transport becomes of major concern. Computational HAM modeling covers the numerical solution of the coupled differential equations supplied with initial and boundary conditions. The quality of the predicted responses depends on the quality of input data, - material properties and boundary conditions - and on the robustness, precision and efficiency of the applied numerical techniques.
This first series of courses aims at providing the participants with the knowledge of the fundamentals of heat, liquid water and water vapor transfer as well as with the latest advances and developments in this field. To this extent, the course has been composed as a unique combination of theory and exercise, covering a wide range of topics including material properties, experimental techniques, state-of-the-art models, special materials, basic and advanced numerical procedures, an introduction to Computational Fluid Dynamics, detailed indoor and outdoor boundary descriptions, climate, etc.
The second series of the courses will be given in 2006 and will deal with coupled air and heat-moisture transport including whole building simulation. Current and new research directions in moisture durability assessment will be presented.
Because of its nature and content, the course is valuable for researchers, graduate and Ph.D students and engineers.

B. Blocken
- Boundary 1: wind, building aerodynamics, CFD, wind pressures, boundary layers.
- Boundary 2: wind-driven rain, runoff, surface condensation, evaporation, hygric boundary layers, vapour transfer coefficients.
- Boundary 3: convection, thermal boundary layers, solar radiation, long-wave radiation, heat transfer coefficients.
- Boundary 4: indoor and outdoor climate, comfort, global change and HAM modeling.
The format of this course includes morning sessions, where the fundamentals are thought by experienced researchers and afternoon sessions, where theory is applied through practical exercises and experimental testing. The course is divided in two blocks: transport and boundary conditions.
Wednesdays are attributed to exchange of personal research, discussions and practical workshops.

Biographies
Paul Fazio has been professor of Engineering at Concordia University since 1974 where he founded the Centre for Building Studies in 1977 and established the new discipline in Canada of Building Engineering at the Bachelor, Masters and Ph.D. levels. He chaired the Department of Civil Engineering for 6 years and the Centre for Building Studies for 21 years. He has published extensively and supervised to completion some 40 Masters and PhD graduates in the area of building engineering. He is a recipient of the Galbraith Prize and of the Gzowski Medal; he is Fellow of CSCE, ASCE and EIC. He is a registered professional engineer in Quebec and in Ontario. His current research activities focus on the building envelope including projects on curtain walls, moisture movement in wood-based envelopes, and industrialized building. He consults in the area of the building envelope, total building performance, and patent infringement.
Hugo Hens has completed his engineering studies in 1968 at the Katholieke Universiteit Leuven (Belgium) (Building technology). After 4 years in industry, he was full time researcher at the University of Leuven, Department of Physics. He got in 1975 his Doctor's degree in Building physics. From 1976 to 1981, he was assistant-professor at the University of Leuven, in charge of the lectures in Building Physics and building construction and started the Laboratory of Building Physics in 1978. Since 1981, he is professor at the University of Leuven, responsible for the lectures in Building Physics (part 1, heat and mass transport), Applied Building Physics (performance approach) and Building Services (Heating, Ventilation, Air Conditioning, Sanitary installations) and head of the Laboratory of Building Physics. His research and consulting activities lie in Energy and Performance analysis of building elements and buildings.
Bert Blocken is a post-doctoral research engineer of the FWO-Flanders (Fund for Scientific Research, Flanders) working at the Laboratory of Building Physics, Department of Civil Engineering, Katholieke Universiteit Leuven. He graduated from this university in 1998 on the thesis "Damage detection based on dynamic system identification". In 2004, he defended his Ph.D. thesis "Wind-driven rain on buildings - measurements, numerical modelling and applications" at the same university and is currently involved in the postdoctoral research project "Multi-scale modeling of wind-driven rain as a boundary condition for research in building physics and earth sciences".
Jan Carmeliet is full professor at the Laboratory of Building Physics, Department of Civil Engineering, Katholieke Universiteit Leuven (Belgium) and part-time at the Building Physics Group, Faculty of Building and Architecture, Eindhoven University of Technology (The Netherlands). He earned his Ph.D. at the Katholieke Universiteit Leuven in 1992 on the thesis "Durability of fiber-reinforced renderings for outside insulation: a probabilistic approach based on the non-local continuum damage mechanics." He has published more than 50 papers in international journals and more than 100 papers in international proceedings. He currently leads a number of Ph.D., post-doctoral and other research projects in the area of heat and moisture transfer, in the area of durability mechanics and in the area of CFD in building engineering.
Hans Janssen earned his Ph.D. in 2002 at the Katholieke Universiteit Leuven, with highest distinction, on "The influence of soil moisture transfer on building heat loss via the ground". He is currently working as a postdoctoral researcher at the Laboratory of Building Physics at the Katholieke Universiteit Leuven. His current topics of interest focus on the transfers of heat, air and moisture in building materials and their associated mechanical effects, with an emphasis on the numerical modeling of these phenomena.
