Uni & Visiting Experts to Look at Leaky Building Crisis
The country’s leaky building issue is being tackled head on, with the inaugural Leaky Buildings Symposium organised by
the University of Auckland.
The Symposium, which will be held on July 18 and 19, has attracted two of the world’s most respected experts: Canadians
Dr John Straube and Dr Joseph Lsitburek.
Both have been key players in the Canadian leaky building saga and will present their current thinking as well as the
latest world research.
Dr Straube is a director of the University of Waterloo (Canada) Building Engineering Group that undertakes R for the building industry whilst Dr Lsitburek is a forensic engineer who investigates building failures.
Auckland University’s Prof. Geoff Duffy, Professor of Chemical Engineering and Associate Dean Engineering Research, is
one of the proponents of the Symposium. Prof Duffy and his team at the University have been involved in research into
moisture effects, accumulation and transport mechanisms for some time.
“We are not looking for ‘who’s to blame’. We need to cut a swathe through all the talk and dishonesty and get through
this minefield to create a platform of truth so we can build solutions ,” says Prof. Duffy.
Prof Duffy says the subject is controversial, complex and varied.
“We aim to table the issues, face up to the reality that there is no single blame and cause ,or single solution and then
work together to find the best possible outcome for this iceberg of a problem.
“There has been valuable research done both here in NZ and overseas and this will be presented in the light of building
future buildings right first time.”
The Symposium will cover the scientific causes of leaky buildings, practical ways of fixing them, legal issues
surrounding the situation and converge on the vision of industry leaders in ensuring quality homes for all New
Zealanders.

Waterloo in Canada, where he teaches courses in material science, structural design, and building science to both
disciplines.
He is a prolific writer and presenter authoring over 20 conference papers, many articles and has delivered over a
hundred presentations around North America on building science.
He is the director of Building Engineering Group (BEG) at the University of Waterloo, a multi-disciplinary research
group that undertakes research, development, and demonstration (RD) for the building industry. BEG is a non-profit and non-proprietary organization within the Civil Engineering
Department at U.W. and operating together with the School of Architecture. He also runs his own consulting firm Balanced
Solutions. Dr Straube is an Associate Member of ASHRAE.
Joseph Lstiburek, B.A.Sc., M.Eng., Ph.D. (University of Toronto) is a principal of Building Science Corporation and an
acclaimed public speaker and lecturer in building science.
He is a forensic engineer who investigates building failures and is internationally recognized as an authority on
moisture related building problems and indoor air quality.
He is a member of ASTM and the past chairman of ASTM E241 - Increasing the Durability of Building Assemblies from
Moisture Induced Damage. He is a contributor and reviewer of Chapters 21 and 22 of ASHRAE Fundamentals and a voting
member of ASHRAE Standard 62 – Ventilation for Acceptable Indoor Air Quality.
He is also a voting member of ASHRAE Technical Committee 4.3 Ventilation Requirements and Infiltration and ASHRAE
Technical Committee 4.4 Building Materials and Building Envelope Performance.
