The aim of the research is to determine the degradation in natural ventilation between BoM monitoring stations and a variety of dwelling types through monitoring of wind conditions in SEQ. The research will verify and quantify the role natural ventilation has in cooling residences in subtropical climates, inform the development of a lot rating methodology for SEQ and may also make a recommendation that the existing lot rating methodology in use in other parts of Australia, be modified to allow for the impact of ventilation. The research is also expected to highlight the importance of good design and will also inform the ongoing development of thermal programs.
