Abstract

This thesis explores the design and construction of greywater irrigated detached green façades, assesses their seasonal water requirements, investigates the leaf-scale transpiration and its impact on cooling, and assesses the impact of greywater on water quality. Green façades with deciduous climbers had half the water requirement of façades with non-deciduous climbers in winter. A significantly higher leaf-scale transpiration rate of Hardenbergia violacea did not provide greater cooling and the growth media acted as a source of nutrients. The findings of this work demonstrated that green façades were viable in Perth's Mediterranean climate and could be implemented for urban development.
