As we journey into a new century of civilisation we find ourselves looking back on the previous 100 years and how the world we live in has changed. One of the most significant things we notice is the substantial increase in our consumption of resources and the constant degradation we are placing on the plant. As the notion of repairing what we have done resides in our minds, it creates an opportunity to look at alternative building typologies and technologies within our own locale. These typologies may not be new and potentially have been used throughout other societies, however, it is time to use this current interest to delve into and research the viability of these systems and their functional ability in our ever changing environment.
Green roofs provide many advantages which include; thermal insulation, reduction in the heat island effect, reduction in pollution, replace lost habitat for flora and fauna, storm water retention, and many more. These advantages are supported by significant research that has been conducted throughout the northern hemisphere. Most of these advantages are universal and their effectiveness is based on location, however, there is a lack of any significant research in a sub tropical climate.
This thesis will examine the two traditional types of green roof systems and develop a technical solution for a sub topical green roof system. It will also effectively illustrate what factors need to be considered in an installation and what effect it will have on the building structure.
