Heat & Moisture Simulation Workshop | Assess Risk & Prevent Interstitial Condensation
Is the building you are designing or retrofitting:
- traditionally built or a protected structure?
- to feature a solid wall or unventilated roof buildup?
- tall or in an area of strong winds?
- damp or considered problematic?
- to be fitted with internal wall insulation?
- to be made very airtight and highly insulated?
- to feature timber in vulnerable positions, like joist ends?
If you are concerned about interstitial condensation, mould or rot then you need to evaluate the risks with WUFI® Pro.
This two-day ONLINE course provides a practical, hands-on introduction to WUFI® Pro hygrothermal numerical simulation. WUFI® is the world leading simulation software for understanding the risk of interstitial condensation, mould, rot and freeze-thaw in buildings.
The WUFI® training will run from 9:00-17:30 on Day 1, and 9:00-17.00 on Day 2. You can access the full event programme here.
The training includes hands-on guided use of the software, and a 6-week temporary licence of the full version of the WUFI® Pro software, as well as access to support on the online WUFI® Forum for that period.
Guidance & Assessment
Despite WUFI being available since 1995 and being validated to BS EN 15026 since that standard was first published in 2007, it was only in 2016 that BS 5250 - the Code of Practice for Control of Condensation in Buildings referred to BS EN 15026 and acknowledged transient hygrothermal simulation (as ‘full modelling’). In the last few years the Code of Practice has been significantly re-thought and re-written. The 2021 edition of BS 5250 is underpinned by an ethos that is more up-to-date, more risk averse, more focused on capacity, systemic thinking and in-service conditions.
Since 2012 an increasingly coherent library of serious, peer-reviewed guides has been published to support appropriate specification, particularly of renovation of historic buildings. One of these Technical Paper 15, authored by J. Little, C. Ferraro and B. Arregi, published by Historic Environment Scotland) will be referred to alongside BS 5250 in the 2-day workshop. BS 5250 may be purchased here. Technical Paper 15 may be viewed or downloaded free (as pdf) here.
Despite these positive changes, most building material suppliers and many building design professionals still prefer to carry out hygrothermal risk assessment using the Glaser Method. Section D.3.5 BS EN 15026(2016) states the limitations of the Glaser method. ‘This method assumes moisture transfer is affected solely by diffusion; thermal conductivity and thermal resistance of materials are assumed constant; the effects of phase changes and the specific heat capacity of materials are ignored’.
The Glaser method cannot assess the impact of:
- imperfect construction (such as air leakage in internal air barrier and rain ingress at cracks)
- short-term weather events (like driving rain and freeze thaw)
- orientation and exposure
- hygroscopic materials (like brick, plaster, timber and many insulants)
- construction moisture
- material characteristics that vary (depending on changes in moisture or temperature etc.)
What is the sense of assessment that excludes real world conditions and variability? WUFI® Pro can be used to assess all such conditions and more.
Topics discussed will include the vocabulary and fundamentals of building physics, practical examples with WUFI ® Pro, interpretation of results, the compliance context in the UK, and a review of completed case studies. Particular attention is paid in the course to how one carries out risk assessments when there is a lack of data on the hygrothermal characteristics of commonly used or existing building materials in the UK. Attendees will learn how to input building fabric assemblies, including orientation and location etc., and run simulations on different configurations, including their own projects.
Who should attend?
The workshop is open to all building professionals, e.g. architects, engineers, surveyors, insulation suppliers, system manufacturers, builders and anyone with a focus on fabric performance. No previous experience with the WUFI® Pro software is required.
There are now thousands of WUFI® Pro users around the world and rising fast.
Book now to join the growing ranks of WUFI® simulators. Our previous WUFI® Pro courses have sold out so book now to secure your place!

Course fees include the 2-day course tuition, course materials, and the full version of the WUFI® Pro software with a 6-week temporary licence, as well as access to support on the online WUFI® Forum for that period.
Participants must have a MS Windows-compatible laptop (on which they have administrator privileges) and will receive the full version of the WUFI® Pro software with a 6-week temporary licence.
About the Speakers
Christian Bludau, Dr.-Ing., Senior Researcher - Fraunhofer IBP, Germany
Christian Bludau is a researcher at the Fraunhofer Institute for Building Physics, Department for Hygrothermics, in Germany. Christian received his Diploma in Civil Engineering at the Technical University of Munich, Germany in 2001. After his studies he worked as research assistant at the Institute for Building Materials and the Institute for Structural Engineering at the University of the German Armed Forces in Munich.
He has worked as researcher at the Fraunhofer Institute for Building Physics since 2005 and from 2011 to 2015 he had held a lectureship for building physics / moisture control in buildings at the University of Applied Sciences in Augsburg. He finished his PHD with the topic "Special boundary conditions for the hygrothermal simulation of flat roofs in timber constructions" in 2021. His research interests focus on the hygrothermal conditions in wall and roof constructions with special interests in the thermal behaviour of flat roofs. Christian has been involved in many WUFI® seminars, lessons and workshops during the last few years.
