Coupled Heat, Air, Moisture and Pollutant Simulations in Built Environment Systems (CHAMPS-BES): Modeling VOC Emissions and Sorption of Building Materials

Full Workshop Description


Workshop summary: The course is intended for Ph.D. and M.S. students with prior knowledge of undergraduate levels of heat and mass transfer. It provides an in-depth discussion of the fundamental mechanisms and processes involved in the emissions of volatile organic compounds (VOCs) from building materials and indoor furnishings. Influencing factors to be considered will include the material properties (such as material composition, porosity, and specific surface area), chemical properties of the VOC species (such as the molecular weight and vapor pressure) and environmental conditions (such as air temperature, relative humidity, air velocity and concentrations). A coupled heat, air, moisture and pollutant simulation (CHAMPS) model will be introduced, detailing the governing equations, initial and boundary conditions, numerical scheme and interpretation of simulation results. Several case studies, from simple to more complex ones will be used for in-class exercises to enhance the understanding of the fundamentals as well as developing practical modeling and simulation skills. Participants should bring their own laptops for in-classroom exercises in groups, while a computer room with 35 desktops will be available for use outside the classes.

Date: September 21-23, 2018

Total contact hours: 15 hours, 2.5 days

Number of participants: 15-30

Course fees: $150 (including a USB containing the course presentations, reference materials and software to be used)

Airflow modeling in and around buildings using OpenFOAM and Energy Plus

Full Workshop Description


Workshop Summary: Participants will learn modeling approaches to simulate airflow around and through buildings to inform Building Energy Models (BEMs). The two simulation tools used in this workshop are OpenFoam and EnergyPlus through Eddy and Archsim, which enable the participants to run BEMs coupled with accurate ventilation boundary conditions provided by Computational Fluid Dynamics (CFD). It is recommended that participants have good understanding of energy modeling, CAD modeling with Rhino and Grasshopper.

Additional requirements: Laptops with Windows 10(!) and Rhino 5 / Grasshopper and at least 10 GB remaining space on the HDD.

Date: September 23, 2018, ½ day

Course fees: TBD

CIB W040 Research Roadmap: Determining Stakeholder Needs

Full Workshop Description


Workshop summary: This workshop is for everyone who is involved in or would like to be involved in the international CIB W040 Working Group. We are drafting a Research Roadmap to determine stakeholder needs for increasing moisture safety in buildings and reducing the risk of moisture damage. During this workshop, the project and the guiding principles behind the concept will be presented. The project framework will be refined, and the research projects and new academic studies from graduate students will be discussed (i.e. Master’s theses and doctoral dissertations at the partner institutions, and question papers). The results from the initial questionnaires in the member countries for different architectural and engineering groups will be presented, and strategies for collecting data from the other stakeholder groups will be discussed. The scope of this project is to promote moisture safety in all buildings (i.e. new construction, renovations, protected buildings, and all building uses). Each member who has conducted a needs analysis study will present his or her results. Participants will agree on a timeline with milestones for submissions, questionnaire launch, analysis and dissemination. New members are very welcome to join the CIB W040 Research Roadmap. Information is available on the website,

Date: September 23, 2018, 10:00am to 4:00pm

Total contact hours: 6 hours, including lunch and refreshments

Number of participants: 15-20

Course fees: TBD

Contact: Prof. Thomas Bednar, Naomi Morishita, Research Center for Building Physics and Sound Protection, Institute for Construction and Technology, Faculty of Civil Engineering, Vienna University of Technology

Immersive Simulation Representation through Virtual Reality

More information will be forthcoming

Workshop Summary: This workshop investigates the capacity of virtual reality (VR) to facilitate the communication and understanding of the quantifiable information generated through design simulation and analysis. It will introduce participants to VR as a representation tool, demonstrate how virtual environments are generated, and invite participants to collectively build a virtual environment which includes 3-dimensional data representations of their own design.

Date: September 23, 2018, ½ day
