Pei-wen Chung assessed the effect of greywater irrigation and limited substrate volumes on green façade plant performance.

Benefits that green façades provide for urban areas include microclimate improvement, urban heat island mitigation, biodiversity enhancement and contributing to the health and wellbeing of locals.

Saving energy and water conservation, particularly in densely populated cities, has become increasingly important as resources become scarcer and more expensive.

Façade plants can reduce the building surface temperature and contribute to energy savings through cooling mechanisms including shading (leaf coverage), evapotranspiration and thermal insulation.

Previous studies have primarily focused on the relationship between cooling and building energy savings instead of the morphological and physiological traits of climbing plant species, which are the essential factors in determining the cooling mechanisms of green façades.

My research emphasises the water usage strategy of green façade plants and limited resources on façade plant performance through growing these façade plants with greywater irrigation or in limited substrate volumes.

Assessing plant traits and the performance of climbing plants under these treatments gives us a better understanding of plant selection for cost effective green facades.
