Details

Condensation problems in Australia have raised serious questions about the reliance on infiltration, and the reliance on occupants opening windows, to provide sufficient make-up air. Airtightness is increasingly being taken seriously in Australia, and is happening by default in class 2 buildings as construction methodologies, products and skills improve. Continuous ventilation and makeup air is on the agenda. There is a need for cost-effective, simple, non-disruptive ventilation strategies that can deliver good results. Regulation needs to consider occupant behaviour and seriously consider a continuous ventilation requirement. There are valuable lessons, positive and negative, that can be taken from different regulatory approaches as different countries evolve and introduce effective ventilation for tighter buildings. Andy will present the results and learnings from a CFD analysis conducted in partnership with Massey University in Auckland, on different ventilation strategies for typical apartment in a multi residential building. Seminar Cost - $30

General Manager
Proctor Group Australia

A global journey from natural ventilation with operable windows, to continuous mechanical exhaust ventilation with passive demand control.

.

Andy has worked with building envelope specialists Proctor Group in the UK and in Japan, including a spell on secondment to a major prefabricated house manufacturer right at get time Japan implemented the Building Standard Law to address indoor air quality. He was a contributor to the first edition of the “Condensation Handbook” published by the ABCB in 2011 and has presented across Australia on the subject. Andy is motivated, however possible, building by building, to improve the health and comfort of our built environment and positively impact the health of current and future generations of occupants.
