For years Australia’s standard construction methods have lagged behind the rest of the developed world. Most Australian timber frame and brick veneer houses are inundated with unseen mould within the wall cavity which has a detrimental effect on short- and long-term health.
Recently industry and construction standards have started to make changes (slowly) to rectify this serious issue, but there are many important basics not standardised like our European or North American counterparts.
The healthy house method is a pillar of the passivhaus theory developed in Germany. Healthy house design has been a popular concession for those not willing to commit to a full passivhaus design, but still want to have the health and increased energy benefits over standard construction.
