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 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 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: in the Summer of 2020 it was sent out to public consultation. We have been told that the revised document is underpinned by an ethos that is more up-to-date, more risk averse, more focused on capacity, systemic thinking and in-service conditions.
Moisture in Buildings: an Integrated Approach to Risk Assessment and Guidance authored by Neil May (RIP) and Dr. Chris Sanders (published by BSI) and Technical Paper 15 authored by J. Little, C. Ferraro and B. Arregi (published by Historic Environment Scotland) are two key documents in the emerging library of serious, peer-reviewed guides to applied building physics and risk assessment of historic buildings that have been created for building professionals. Both documents are available free as downloadable pdfs and form a context for this training course.
Despite these positives 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 asses 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.

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. 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.
Joseph Little, BArch, MSc Arch. AEES, TU Dublin
Joseph Little is Assistant Head of School at Dublin School of Architecture in Technical University Dublin (which replaced DIT on 1st January 2019). He is programme chair of MSc in Building Performance (Energy Efficiency in Design) which has a blended online mode of delivery. He graduated from the UCD School of Architecture in 1996 and from the Graduate School of the Environment at the Centre for Alternative Technology, Wales, in 2008. Joseph set-up his own practice in 2003 when he realised that his passion for low energy, environmental building design could only be realised outside of mainstream architectural practices and launched Building Life Consultancy in February 2009.
Since 2010 Joseph has taught hygrothermal risk assessment using WUFI® Pro with Fraunhofer IBP across the UK and Ireland. He is co-author of Historic Scotland Technical Paper 15 - 'Assessing risks in insulation retrofits using hygrothermal software tools - heat and moisture transport in internally insulated walls’ and 'Hygrothermal Risk Evaluation for the Retrofit of a Typical Solid-walled Dwelling' (SDAR* Journal, Vol.4, Iss.1). The hygrothermal risk assessment module of the MSc in Building Performance is available to UK building professionals (subject to qualifications) as an online CPD delivered over 5 weeks, cementing the knowledge gained in this workshop.
What did delegates say about previous WUFI® Pro Workshops?
"Very good ... most useful was an overview of WUFI Pro, its function, versatility and application in many areas giving me a better appreciation of the software ... Enjoyed the case studies."
"Excellent ... useful tutorial and hands on training with software ... unbiased views & discussions on industry conventions and software."
“Very good mix of theory & worked examples – didn’t assume we already knew everything."
"Excellent ... Great volume of material to study, and the speaker’s expertise and experience."
